Rendering In SketchUp presentation

thank you everybody for joining us again a third time is the charm name is Daniel Totten we’re just going to jump into it I have a lot of information to go over and I’ll explain as I’m going along here’s just you can see there’s a Sketchup image on the front of the screen and then clicking on the next slide and I’ll wait for the attendee viewed up to actually catch up and there’s the rendered version and that again that was rendered in Sketchup using a program called Twilight render and we’ll cover all that I’m going to skip this part about Who I am since we just went over that that’s Google Sketchup for site design and yes this presentation is based on this book what is rendering well rendering is the act of taking any kind of Sketchup model or any model for that matter and this is an interior design model by an interior designer named Carol X and she won this for a competition for Easter Seals and I tweaked them out a little and then I rendered it so I took this interior model rendered it in something called Twilight render and produced a photorealistic quality to that model again another example um this process that I’m talking about is Universal it doesn’t matter what type of model that you’re actually working on the results are going to be the same so here’s this architectural model in Sketchup and then it’s rendered again in our in an integrated rendering program inside Sketchup to produce the photorealistic result and again just to get to the more traditional landscape architecture type of project here’s a here’s a park project and then it’s rendered to pre to create a photo realistic effect and the purpose here is to say well given the tail what’s going on with all the different rendering programs and Sketchup after so many years which will hopefully talk about at the end you can render landscape and vegetation at this point without too much brain damage though sometimes there is depending on your computer or if you’re depending on what you’re doing um rendering in itself is a complex and large topic that’s why the book itself is a reference guide and I’m not going to mention the book beyond that um but I want to review the basics and I want to focus on a couple of things one my personal take on how I model and how I renders needs to be done in Sketchup and the way that I’m using Sketchup to create these renderings I can use multiple rendering programs there’s a couple of things that I’m going to try to touch upon at the end but it’s not the focus of this presentation but and you can ask and let’s see if we can get to it but it’s computer specs post-production on what to do with images after they’re rendered a lot of rendering artists take them into Photoshop or similar programs and adjust them and then simulate it or artificial lighting which is an example of what you’re seeing on this screen is the bottom rendering was actually done with simulated bulbs or in the rendering program but again those are pretty complex topics in their own right so I’m going to start with this chart and if you’re not a chart person don’t worry about it I’m going to show some visual examples but let’s talk about process I’m all about process process is really the key to everything that we’re doing is landscape architect’s anyway and rendering is no different so you model in Sketchup you create your base model we’re going to talk about that you’re going to obtain and apply texture images to it you’re going to add and control the model detail and then you’re going to set the lighting up in Sketchup what I mean by set lighting is we’re just going to use the Sketchup Shadow menu to determine how lighting works then I talked about an iterative rendering process you’re never going to get the correct rendering on the first shot that’s not the way it works you have to actually process your image multiple times tweaking adjusting adding details removing or swapping out textures so you’re going to go through a draft rendering process leading to the final rendering during the iterative rendering process what you’re actually doing is applying specific values to the texture – textures and lighting and output and we’ll talk about that in detail as well and then there’s the post-processing part which we’ll talk about again I know I keep saying we’ll talk about at the end but we’re going to go through some of that right now so if you don’t like diagrams here’s an image about this here’s some images about this process here’s the base model in Sketchup what do I mean by base model I have three buildings I have my ground plane it’s delineating my open space on the back on my heart scape I have a pool on the left over there and that’s my base model in Sketchup I then take this base model everything has a sketch of color to it and I apply textures to what are textures textures we’re going to talk about our photo our images that represent real-world materials they get scaled in Sketchup to represent real-world materials and then we will and those are probably the most important aspects when it comes to rendering is actually applying successful materials and textures to your model then I apply another layer of detail to my model and in this case it looks like I’ve added a lot but I really have taken seven components people benches bollards table and chairs

pedestrian light and a trees to really fill up the scene to create context for my rendering and again I’ll elaborate on all these aspects as I keep going on then prior to rendering again I’m still in Sketchup here I turn on the Sketchup shadows and the way the rendering programs work is whatever you set the Sketchup shadows to be is how they’re going to render what’s nice about a lot of rendering program sounds you don’t have to turn the shadows on or keep them on but what i’m doing here is assessing the scene as i’m looking at it on prior to rendering I’ve turned off the Sketchup edges I’ve turned on a little bit of fog and that actually starts giving me this notion of what this photo real image is going to start looking like then we talked about after I set all that in Sketchup I mean I start applying the rendering values here I’m actually showing three separate rendering programs on the left is podium in the middle is shader light and on the right is Twilight render those are the three that I’m just referencing there’s many more we’ll talk about that and their menus are really just very simple plug-in interfaces within Sketchup that let you actually start applying these texture values to the materials and your the values you’re going to apply is how textures render the final output the quality of the image um and what kind of lighting and again here’s another example of the rendering plugins and just the secondary menu and usually when you’re rendering and doing an exterior rendering you’re only really going through a couple of menus which is nice because it lets you quickly lead to the rendering so talking about the draft rendering process I know when I first started running I was like a God you know I created my first render and you could see my first render here on the top left the windows are too dark my green space looks like a pool my buildings look flat umm the view doesn’t look necessarily correct but that’s part of the rendering process and learning how to render and that’s something have to be patient with the way that you want to do the draft rendering processes you set up everything so it’s fast the renders get processed very quickly so you can assess the renders make your changes and then re render the entire thing so here I’ve gone through five different iterations of rendering adjusting lighting adjusting the texture values you can see I got my windows much better in the top right and the bottom images here and the same with my green space on the back and also the amount of detail it’s visible and then it gives me it takes me to my final rendered image here we’ll wait for a second as it catches up for everybody again I can see an audience view of how fast images are showing so sorry if I have to wait for that um but again there’s the final rendered image um and then I can take my final rendered image and I bring it into Photoshop and make some adjustments to it they’re very subtle in this case the most obvious difference is actually adding a sky background but I’ve added some haze um I’ve tweaked or adjusted the water in the pool at the bottom left so it’s a little bit more realistic and that really sums up the entire rendering process in a nutshell but let’s delve into the details of this I’m sorry before I do that let’s talk about rendering programs so there’s two types of rendering programs there’s Studio rendering programs like 3ds max karakia and I’d actually like to give out a shot a shout-out to Rashad who might be here tonight and lumen which is actually something I’m going to go play with over the next couple of weeks because it’s a very promising studio rendering programs um most studio rendering programs have steep learning curves they can be expensive some are free like Erica Thea what you have to do is you import your Sketchup model into the studio rendering program um and in general this is an example by a Keiko Okabe she’s a rendering artist that are now you could see what she’s doing with 3ds max it’s a gorgeous rendering and in a lot of cases the studio rendering programs might give you better result ehn integrated rendering programs or IRPs here’s Twilight su podium and shader light um they have very simple learning curves they work inside Sketchup they’re relatively affordable they range from anywhere from a hundred to two hundred dollars and if you learn how to use one you learn how to use all of them the process is really dependent on how well you model in Sketchup what we’re also seeing with these new integrated rendering programs like shader light and there’s going to be new generations of su podium and Twilight render is we’re now looking at the second and third generations of these programs they’ve gotten a lot of feedbacks from users they’ve worked more integrated with the Sketchup itself and their quality is becoming very superior almost parallel to studio rendering programs again the big difference between these programs is one works in Sketchup one works outside of them some people will claim it’s easier to use the studio rendering programs I leave that up to you I know that using the integrated rendering programs is a great stepping stone if you want to go start working with studio rendering programs

like Lumi enlike carroca Thea like um 3ds max so again here’s the integrated rendering program this is shader light Twilight podium these are what constitutes their menus in Sketchup and don’t be deceived even by the number of buttons on the Twilight render menu you’re only actually going to use two or three of them at a time here’s a complete list if you go to sketch ups website they don’t have a complete list of studio rendering programs but they have a pretty comprehensive list of other rendering programs you can use within Sketchup so how is this process Universal how do I mean you can use any rendering program and the key to it is how you use Sketchup and prepare your model well here’s a Sketchup model of your interior we will get to exterior stuff as well don’t worry um but I take this Sketchup model and then I render it in all three rendering programs so I took it and I rendered it in Twilight render and you can see there’s one quality and I change the backgrounds up I did a post Photoshop for all the backgrounds through the windows and each rendering program but this is Twilight or then I can take it into su podium and you can start seeing the differences in the render quality of it or you can do it in shader light same model three rendering programs that’s why the process is universal and I know I’m going to get asked which one do I prefer um I it depends each one has capabilities that I like even ones that I’m not showing you and like render in for example or Maxwell render each one does something different that I like if I can combine them all into one program might be happy but in this case I just end up using whichever one might seem appropriate for me at the time okay so let’s talk about texturing your Sketchup model texturing is the most important part of the process here you’re seeing this little alley and I’m going to go to the next slide here you’re actually using the Sketchup Paint Bucket I’m going to demonstrate that to apply materials to scale materials um there’s a lot you can do in Sketchup and how you make textures appear but in this case what you’re seeing here is again this is the Sketchup model the shadows are on I’m setting the Lighting’s and I’ve turned the fog on but I’m assessing the textures worst and foremost why because I know if I if I can get it to look right in Sketchup prior to rendering it’s going to look signed while I render it in this case the textures to the ground plane are correctly scaled I have textures for the brick that come across is looking semi real or realistic in here same with the benches and all the details in place that way I can assess what I know is going to what it’s going to look like prior to right before I render it and then I just click the render button after I apply the values again and you can see that it adds the reflection and a little bit of depth to the textures but again the key part is actually working with textures correctly in Sketchup well how do you do that well what are textures textures in Sketchup or materials are really just images they’re images of materials they’re plan view images there’s something called seamless and tiled images I’m not going to get into too much detail about that because I could spend a whole hour talking just about textures but all they are these are the texture images in Photoshop and they get applied to this the model surfaces in Sketchup and what Sketchup ends up doing is it tiles the image onto each surface to create the reality of this of the textures on the surfaces themselves um you know and they’re all this is this what you’re seeing and you’ll see it in a second if it hasn’t caught up wait for it you’re seeing the Sketchup material menu by the way I just one note there is a big difference between the PC versus the Mac version of the material menu I’m focusing on the PC one on the Mac version I’m gonna have a free chapter on that online about how to use them the Mac material menu because it’s a bit more complicated but the Sketchup does come with its own native materials they are useful for rendering but they’re limited they’re limited in number so you can’t really represent a wide variety or different types of sketch of textures and they’re limited in results the reason why is they’re lower resolution they sometimes don’t come out as well um one of the things that you have to do and I’m going to emphasize this point with components as well but textures as much as anything else you need to build a texture library what is a texture library it’s a folder that has subfolders that represent a wide variety of different materials from asphalt to concrete to granite to flooring to wood to roofing to whatever I’m you can see here’s an example of some of the materials that I have in that represent a texture library and then for example texture library brick and you can see I have a whole selection of different types of brick um textures that I use how do I end up creating my texture library I’ll show you that as well I’m going to give you some very specific resources for that next but I do it on a per project basis any time I’m going to start working on a project or anything I’m going to do I’ll go download some textures I’ll organize them in the folder and I can use them

again later on um but slowly and surely you build up a texture library um there’s a couple of really good places to get textures um one of them that I love is a website called CG textures calm and um what it is is you can see there’s a bunch of categories on the left side these are ideal and are directed for CG computer-generated graphics membership is free you can download up to ten megabytes of small textures a day um for a yearly subscription of seventy dollars you can download a hundred megabytes a day well what’s nice about um Sketchup in that capacity there’s small medium and large texture sizes on CT textures you only need to download the small ones well there’s also another I’d like to give out a shout out to my friend John Pass ego who runs the Sketchup for landscapes blog and I’m going to actually give you that link in here as well so give me one second as I switch out of PowerPoint I apologize for that but I just want to show you here’s CG textures calm but then there’s also John Positas blog here in a specific blog post I’m gonna put it in the chat window and what he’s done here is he’s actually listing a ton of for pay and if not hundreds of free texture websites so you can actually go get your textures from this website and he’s got a he just spent a lot of time getting all these textures organized into it and you can see it just goes on and on so if you don’t want to get the for pay ones um again there’s just tons of places to go get materials for for Sketchup so you can easily build your texture library which again I highly recommend that you do so that’s where you can obtain textures let’s talk about what you do with them so the Sketchup material menu is key to actually using it because you have to both use the Select and you have to know how to edit textures as well and it’s something you have to get very familiar with this particular menu to use it correctly aside from that there’s a very specific way you want to actually model in Sketchup you want to apply colors to everything in text in Sketchup so let’s say you start modeling your project you’re not really sure what the materials are going to be apply a solid sketchup color to it why you’ll be able to take any solid sketch of color and swap it out if you go the route and i know a lot of people do this when you model and you don’t apply any materials you just use the default Sketchup material which is really not a material the problem with that is you cannot actually adjust those later and and swap out the colors as easily you have to go apply your materials to every nook and cranny within this model that doesn’t that doesn’t work well and I’m going to demonstrate why in Sketchup in a second but let’s keep going with this so here’s an example image of this window in the staircase for this project in Denver called taxi and everything that everything has a solid color that will represent a future material so once the colors are applied as I’m modeling them I can quickly go and swap them out again this is in Sketchup the edges are on the shadows are visible you’ll see that one second is the view catches up but I’ve with one click I’ve actually swapped out the solid colors with a texture image that’s a quick way for me to edit it and actually go through the process of editing all these materials in Sketchup and applying them and then I simply render it this is rendered in Twilight and you can see the textures themselves get bumped up to a photorealistic level and give us the results that we want so that’s one of the most important aspects of actually rendering and I’m going to switch out I’m going to talk about this in Sketchup in some more detail here um so here’s my Sketchup model and let me just talk about this process real quickly before here’s my site design with my building and you can see there’s no colors apply to these surfaces I then before I extrude any of the surfaces I apply a solid color to all the surfaces here that way when they’re extruding surfaces the extruded surfaces automatically take on the color and quality of the flat 2d surface so it’s a time-saver all the materials have color and then all I have to do is I’m going to use the Sketchup shadow a material editor here I’m going to take the eye drop I’m going to select my texture here and then I’m going to go to edit and I’m going to say use texture image it’s linked directly to my texture library there’s a way of doing that in Sketchup and I’m going to go to my brick and stones and I can pick any one of these bricks and stone I’m going to select one hit open and it applies it automatically to the model so that is the the most important part of this process and how you’re doing it you

could see all the solid colors in this part of this model have now been swapped out a solid color and again if your sis I’m going too fast with this I apologize a lot of information you will get a link in the next couple of days to this video so you can rewatch it the way to link Sketchup to your texture libraries go under window preferences files texture images you link to there you click on that you browse to where your textures are hit ok hit OK and now whenever you select an image in Sketchup or select um I’m sorry a color and texture and Sketchup and click on the Browse button or use texture image you can then quickly swap it out so for example I’ll take some gravel here and you can see it swaps it out so that’s an important part of this process I don’t want that to go forgotten because it’s relatively important okay let’s keep going since there’s a lot more to go over all right so the next part about the next most important aspect of Sketchup is detailing I see a lot of half-done models people don’t know where to get components but it makes a big difference so you can see this park is rendered but I want to add some detail to it not too bad to do not too hard to do there’s some very specific resources out there um that all of a sudden allow you to bring life to this model people buildings that you don’t have the model cars and additional components that let you really create very detailed models now at the heart can of doing this and I say this all the time to people it’s important is creating a component library and particularly you want to really create a very specific component library it includes buildings it includes bridges and you build this over time but instead of just creating your model and bringing in the detailed for that model organization is key to actually this process and actually getting there some very specific detail dings of building this component details but there’s so much out there that’s available now that’s inexpensive or free for example um before I jump into where to get those components let’s talk about the tools that you need to detail your model there’s three and tools in particular that people don’t use well or don’t use enough for use but may not use it correctly or they want to encourage you to use better is actually one of them is the component browser in Sketchup the component browser is like your internet um browser you can link it the component browser to your Sketchup library like textures if you do it correctly you can create favourites that allow you to automatically go into the organized folders of components and quickly insert detail into your model that’s very important in tandem with that is using layers I need a lot of people right now that are using Sketchup proficiently but everybody tells me that they’re lazy when it comes to layers all I can tell you is that the key and by far the most important aspect especially for site design is using layers in Sketchup because it controls both functionality visibility and maintains computer and Sketchup performance I would not be able to build large models if I didn’t use layers and I’m going to actually show you a very specific example the other thing in top of using layers is learning to use Sketchup scenes using Sketchup scenes you can control layer visibility what do I mean by that well let’s say you need to turn off layers or specific layers and you have to go through the layer menu select them turn them on and off and that can become a tedious process what you can actually start doing is using Sketchup scenes and what Sketchup scenes do is actually allow you to sit on save a camera view but it also lets you save layer visibility and shadow settings so in this case I create an off scene I turn off all my detail the off scene is created whenever I click on the off scene it turns off all the detail I don’t want similarly I create an on scene the on scene turn to everything else on so I don’t have to interact with my layer menu beyond creating these scenes and then I can also create very specific scenes in this case I keep all my detail I just don’t want any of the trees to be visible this is an amazing shortcut for working in Sketchup um not enough people do it it’s very efficient you do have to organize and make sure that you use layers and I also use a very specific set of layer conventions to do that um in order to keep my models very organized is that important people always say I cannot build large models and Sketch up this model that you’re looking at is instead shop has a hundred and eighty million faces in it its enormous and using layers I’m able to control it why is that important because then I can go render it and I can create very scenic very detailed scenes once they’re rendered based off using layers and scenes and also the component browser

and making sure that I get the right components that I want to use and using the right components is important but just to emphasize this I’m a stickler for layers layers are highly important and you can see why in this particular example so let me just go through layer scenes in detail fairly quickly and I’m also going to show you links I’m going to go to another model here so here’s that Park model I’m going to open up my layers here it’s a fairly extensive layer list but it’s not too bad and you can see I have a variety of scenes set up to control the layers at the top here so if I click the no tree scene it will turn on all the we’ll give it a second it will turn on all the detail in the model it’ll maintain some level of performance for me or I can go on and turn on everything and it will let me it’ll turn on all the visible trees all the visible detail in this model hopefully without crashing my computer because there is a quite a good amount of detail in here but using scenes in this capacity and again I’m going to click on the off scene um here and it will turn off all the information in the model and that’s so I don’t have to interact with my layers beyond that but that’s really important and key to this modeling process we’ll let this catch up you’ll see the scene has everything off or maybe not Sketchup might not be processing that fast enough I’m going to keep going you’ll see it on the rewind up there you go okay so let’s keep going with a little bit more about components so there’s three places I recommend to get components one of them is 3d warehouse and people like oh god 3d warehouse it’s an unorganized mess the sketch of people know that that’s one of those things are going to work on in the future but one of the things that can do in 3d warehouses get buildings you can use these for your projects you can use these for their renderings I’m adding my own collection to these but there’s tons of buildings on here for context they’re excellent I highly recommend creating a building collection off of 3d warehouse among other things um the next one is form fonts 120 dollar subscription lets you download ten thousand five hundred models a year I do have an affiliation with form fonts for consulting but I do not have an affiliation with them honestly with their models themselves I don’t get any money off of royalties off of their models just to let you know but I’m showing you a sir a sampling of the type of stuff that I love to use in particularly I want to emphasize two of three things one they have a ton of buildings as important if you do a search term on Form fonts for something called the photo figure you will get these 2d people that are excellent for rendering what do I mean by that I use both 3d people and to the people but the 2d photo figures are awesome so here’s a rendering I added people that are seated those are 3d people and then I can add the photo people to the rendering and again these are all using form fonts it’s the best collection where you don’t have to make your own people but it’s the best collection of photo people I’ve seen for rendering I use them extensively and they are constantly updating it the other thing that I love in terms of generic vegetation is the search term on Form fonts called geometries um these are excellent for rendering I’ve actually created my own trees off of these I’m going to upload them for freeform fonts people to use um but what you can do them with them is really great they render really well they’re optimized for rendering so they’re not they’re not going to slow down your system as long as you use layers but you can see the results here in terms of just being able to render with the geometry so again the geometries from form fonts okay there’s another place this is a bit pricier um this is sketch 3d um from dinah scape what dinah scape did len Hornick um they’re their other product manager they created over a thousand types of plants there organized by their Latin names um and they are excellent for rendering I’m using them for prairie models right now um it is a bit pricier um like you know again I don’t have a direct association with them but people always ask where can we get tons of different plants you go to go to dine escape sketch 3d you get your office to invest in them they also have other models on there but it’s the best collection of plants I’ve ever seen for Sketchup and they’re optimized there’s 2d and 3d plants there’s trees there’s grasses there’s perennials there’s boulders there’s vines there’s tools they’re structures on but it’s really intended for the landscape architecture and landscape design community you can see an example of a rendering here in a second this is the taxi development I just spruced it up for a presentation um and you can see some of those shrubs there okay let’s keep going again I’m on the whirlwind of information so Sketchup shadows equal exterior lighting learning how to use the Sketchup shadow menu efficiently makes a big difference

why how you portray lighting and your models will make or break the presentation a lot of people if you have buildings in there they’ll cast too much light into it but you can adjust the Sketchup shadows very easily to get varying results in your models and this is important because you use lighting to create emphasis and focus in your renderings so for example I went with the final setting here for the USDA building on the mall to create the rendering for that and I the way I use the texture so some other ways you want to use shadows in Sketchup not going to go into that but the simplest thing to know to do exterior lighting in rendering you actually just use the Sketchup shadow menu and play around with it to get two results and we’re going to talk about that again here so here’s um in abu-dhabi I think um a project for a promenade um you could see this it’s rendered you see the sketch of the shadows were set so the buildings were casting the shadow versus adjusting the Sketchup shadows to get an entirely different result to highlight the contrast in the building to allow you to see the promenade in this particular case so learning how to use the Sketchup Shadow menus fairly important but it’s also the easiest way to set up lighting for any kind of rendering you can also use the Sketchup shadows to cast into a building into a scene to illuminate a scene in this case I’m casting the shadow into the rendering and you can see that it’s actually lighting up the interior in that particular case so that’s the process that’s the first part of the process that’s really the modeling part and that’s really the most work you’re going to do if you’re already Sketchup modeling some of that should be familiar and you just want to tweak it then you have the iterative rendering process it’s two steps and this is the process you’re going to go through to actually create your renderings um the first step is applying values these are literally numeric values or named values to textures you set the output resolution and quality and you confirm lighting you’re not doing anything else with lighting you’re just going to confirm it and that’s a really easy step um then step two is running the drafts you make adjustments to the model based off the drafts um the reason why you’re doing this is you’re going to run your drafts at lower settings you’re not waiting ten minutes or 20 minutes for a rendering you’re waiting one minute for rendering making the adjustments that you want and then you steadily increase the quality in the resolution as you start producing the drafts but let’s go through this process so let’s talk about textures first so one of the values you apply to Sketchup in using these rendering programs is called bump bump for the best term is called 3d contrast you can see that I’m adjusting the bump value on this concrete on this cube and it’s actually creating depths in and along the creases of the scoring and giving the stone some texture a little bit of bump goes a long way you could see the value of +7 or +8 this isn’t shader light I’m actually the the apply texture again this was a texture applied in Sketchup you’re giving it a numeric value and then it renders in a particular way and that in essence is what is bump here’s an example this is a texture in Sketchup of brick I apply some bump value to it and then I render it and you can see that it starts giving it some depth and some coarseness to actually make it look more realistic so that’s what bump does and bump is a universal value in all the rendering programs you’ll ever see for the most part um and how you apply them and you can see here are some examples of rendered hard surfaces in Sketchup rendered in shader light and they were all given some bump and you can see the result in what they’re doing in terms of having buff the next thing is actually a range of diffusion and reflection so everything in the real world cast or absorb light and you want to give that value and that’s the other set of values you give them these rendering programs is you’re going to give them a range of diffusion to reflection so for example this is in Sketchup I applied values to them and I’ll give you an example of do a little bit of hands-on of showing how do I apply values and then I render it and you can see what happens when I render it the the granite has a little bit of subtle reflection on the surfaces are polished to mirrored and that’s the range of reflections that you’re giving to values in Sketchup I’m going to go back to this particular concrete and hard surface images and just talk about that for a second even these surfaces were given a range of reflection and diffusion everything reflects if you walk around the world world you’ll be amazed at the type of reflections are in the real world and I’m going to talk about that here in this example of the the Utah teapot which is an icon for rendering but I have paint I have my glossy wood surface and I have the ceramic of the teapot itself well I’ve given everything a separate value so the paint has a little bit of reflection a little bit of bump but not a lot but

enough to make it shine then the teapot itself is given more reflection where you can actually see bits and pieces of the background in it I’m starting to become reflective and then finally there’s the gloss on the table itself that’s not a full reflection it’s a little bit more diffuse it’s less reflective than the teapot but more reflective than the paint so those are the ranges you’re giving it to give you another example of the range of reflection you can give in Sketchup so watch the mirror in the background you can see a very slight haze of reflection in it of the car and the teapot in it and then I apply a different value to it and this is just some of the ranges the rain are incredible in terms of reflection and you could start seeing a little bit more of the reflection all the way up I’m starting to add a more reflective value to that surface with selecting more of the surroundings just a little bit more this start starts taking on a little bit of a mirrored reflection all the way to a final mirrored reflection a hundred percent reflection so that’s what you’re really doing to these textures with these rendering programs you’re applying values of diffusion and reflection and then coarseness which is what bump is so one final example this is an su podium of all the different reflection values applied here to the car paint these floating balls this is just a test model for myself to test the different levels of reflection all the way through the entire model and then you can you can give different adjustments I’m not going to go into details I want to do this in a different webinar on how you do water so still water reflection versus water that’s a bit more turbulent but still reflective and transparent all the way to non reflective and turbulent water same thing with glass those have different reflections but again I’m going to one I’m going to go through some very specific texture values as well in a second so just to really talk about how this works in terms of how you apply rendering values you can see here’s my Sketchup model the textures are applied this is the shader light menu I’m going to open up the shader light material menu this is where I apply bump you can see bump is at the bottom here and then I have a bunch of preset um material settings that let me determine the court the roof look how reflective or diffuse I used a sketch of eyedropper I’m going to select the ground plane or actually select the brick here or something else that doesn’t just give me a smooth now everything is going to be smooth but here what you can basically do is you can select from matte satin shiny gloss actually I’m using the wrong model here we go here’s the right model there we go so I’m going to select the windows here it’ll come back it’s going to say transparent thin glass and that’s how you will fly all these settings I want to jump back into my powerpoint presentations I want to talk about specific settings here and this is where you’ll want to review this video so here’s a general chart about how materials work in Sketchup these are not specific to rendering programs this chart is intended as a primer so for example brush metal has an uneven to smooth condition has a hazy to clear reflection and bump can be smooth to coarse how does that translate for example into something like shade or light these are shader light specific settings for this particular rendering on CMU I’m using a very specific reflection type of satin the finish is high one without going into a lot of detail I’m actually giving a range of reflection onto all these materials and again you can use these for your own renderings watch this video again pause it I’m giving you specific settings for metal for stucco for CMU for awnings for glass um just to keep going here is the next image for bike metal for Street polls for concrete paving for signs the whole gamut of the typical range of materials you’re going to find in a model and for anybody that’s doing interior renderings I love doing interior renderings in some ways they’re easier to do than actual exterior renderings in terms of making them look more realistic here’s examples of more settings for you to use um again I’m going to pause here for a second so if you watch this video again you can actually come back and these are specific to shader light not to the other rendering programs again I don’t want to get too much into the book and what that means but I will provide more of that information in the book so the you apply your texture values so how your textures render then the next thing you do is you’re going to apply a resolution to the render resolution is just heightened width so for example this is the Denver justice center pixel width of twenty seven fifty by twenty-four hundred what does that actually mean um your letter size correspond to a dpi that correspond to an output resolution which is what you want to actually do for your rendering programs so if you want a hundred and

fifty DPI image at eleven by seventeen it’s sixteen fifty by twenty five fifty as a pixel resolution output but you do want to use the lower settings because the lower the resolution the quicker the render will keep going and talking about that we’re going to talk about the other thing which is quality when you the other value that you apply in step one is the quality of the rendering this is a low quality rendering setting it’s actually at the lowest and that lets me assess the materials in the textures by having a quickly done render I’m not rendering at a high quality I can go to my next level of quality after I’ve made some adjustments all the way to my final quality quality my final level my hundred-percent quality output once I’m ready to do the final output so then the last value you’re going to apply again is lighting and again we talked about the Sketchup Shadow menu each one of these rendering programs Twilight shadow light podium and all the rest of them have something called physical sky as a setting if you set physical sky in these rendering programs you’re telling them to use the sketch of shadow menu for lighting so I set physical sky here’s the image again I’ve got my sketch of shadow set in a specific direction you can see they’re going to the right and then the rendering program will pick that up and duplicate that exact setting so that’s the first step of the rendering process is setting these values and then setting quality resolution the texture values I’m going to skip this for right now just because I’d like to keep going instead of doing that demonstration I want to talk about step 2 um so iterative draft process so step 2 is you’re going to run a series of draft renders during this process you’re adjusting texture values or you’re swapping out textures that don’t work with an entirely new texture you’re also going to adjust the camera angles you’re going to adjust the lighting to tweak it all these adjustments are done in Sketchup and as you go from draft render 1 through 8 you steadily increase the quality you steadily increase the resolution and you steadily increase the level of detail you start out with low quality low resolution and no detail using layers you turn off trees benches shrubs whatever and that produces a quick rendering so for example my solo resolution equals faster render low detail equals faster render and local all of the equals faster render so here’s my first draft render it’s the initial drafts low quality low resolution the component detail is off and I can start assessing what I want to do what chain what needs to change in this rendering then I keep running additional renderings I keep the resolution in the quality settings low um but I start adding more detail to it still not alive and what I mean by adding details I’m turning some of my layers on so my layers with my benches are on um and it’s not a noticeable increase in render time and I can start making adjustments to this so in this particular case I don’t like the reflection of my windows I might not like the texture so um I’ll keep going from there and I I keep running additional rendering renders really quickly making my adjustments in this case I don’t like my pedestrian lights ended up adjusting them by the time I got to my fourth render um and in this case I’ve started to increase the quality the image is less grainy lower resolution still but more detail is visible then I get to my secondary drafts in this case I’ve increased the quality I’ve increased the resolution and there’s more detail available so I’ve desculpe sure visible I have my table and chairs visible all are high polygons so they do make a difference in terms of impacting render times and this might seem like it’s complex like but it’s not really the key to it is making sure your Sketchup model is organized with layers and I mean everything’s layered correctly and then I finally keep going I add more detail to the time I’m doing my sixth render my seventh render and then I finally get to my last render before I do my final in this case I’ve adjusted my camera angle I’ve adjusted my lighting all my window reflections are correct my backgrounds nice and that will let me go to my final my semi final in my final rendering and before I jump into the rest of that I am going to go into these settings real quickly and show you what I mean by applying output so two menus on shader light that are important and it’s similar for su podium and Twilight render and Maxwell and rendering material menu and output this is the render button this is for animations and this does simulated lighting we’re not going to worry about those real quickly here’s my output so I can set my resolution at the top so I have preset resolutions again lower resolution faster render then I have a quality bar that ranges literally from one to ten or low to high and the lower the quality the faster the render and you can see this is set for 1920 by 1080 high quality rendering and you could see the

physical sky setting these are the most important aspects of it in terms of what you’re trying to do for setting up your draft render quality also the other thing that a lot of rendering programs do if you notice is you can insert background images for skies or context into these menus um and and render them out so let’s go back into my presentation here and then kind of just wrap it up and go see if I can get to the Trimble stuff so once I’m done this is one aspect of it I take my final image I bring it into Photoshop in this case what I’m doing is I’m adding some haze to the image I tweaked colors I tweaked entourage might reek tweak saturation I’ll show you that but there you can see I added some haze here’s another example this is a rendered image um I end up inserting an image into it well let you catch up there for a second and then it allows me to insert my sky in Photoshop that’s the other way of doing it if you don’t insert the background image into the rendering program I also don’t like my ground plane so I’ll actually add some lawn or of additional vegetation and both in the foreground in the background of the hill to create my final rendered image um this is a project in China so that’s what you want to do with photoshop and photoshop for a lot of rendering artists a is the key to actually getting more real results you’re just cue adjust contrast add entourage add backgrounds atmosphere and there’s a litany of other things that you can do there’s other things you can do with these rendering programs just to answer the question you can create simulated lighting so in this case I add light bulbs and I create a lighted scene you can definitely do this with almost all these programs here’s an exterior render with lighting on it in itself for a lance for a residential project and again I personally have this is Kara letting my own model of an interior and I really greatly enjoy that and again there’s a lot of different types of lighting options you can do you can use these for exterior scenes as well to create spotlight results um this is a little art gallery concept I like to create test models that are low poly so I can really play with settings and I’m just going to go through this real quick and
