Getting Started RENDERING IN TWINMOTION (EP 11) - Creating A CITY with Open Street Map

whoo what's up guys Justin here with the rendering essentials comm back with another twin motion tutorial for you so in today's video we're gonna use we're gonna learn how to use the OpenStreetMap integration in order to come in here and create a city inside of your renderings so let's go ahead and just jump into it okay so one of the powerful things about twin motion is it has OpenStreetMap integration built-in that allows you to quickly create full cities inside of your renderings and so let's go ahead and take a look at how you can do that so to start off what I'm gonna do is I'm gonna come in here and I'm gonna delete out this ground that's generally in here when you first open up a twin motion um when you first open up a twin motion file because we don't really need that in there anymore and what we're gonna do is we're gonna go down into the urban settings inside of twin motion so go down here click up the button for urban and we're gonna go ahead and we're gonna bring that in and so the way that we're gonna bring that in is by clicking on the button for context and we've talked about the context a little bit before this is where your backgrounds can be found and where you can adjust those and then there's also the option over here for context and so what the context is gonna allow you to do is that's gonna allow you to actually search for a location and bring it into your renderings and so you can either zoom out and find wherever you're trying to go manually you can definitely do that if you want or you can click on the little magnifying glass right here and type in the location that you're looking for so in this particular location I'm gonna look for Denver Colorado so I'm gonna type in Denver Colorado and I'm gonna pick from the list and I'm gonna go ahead and click on this that's gonna allow me to bring Denver into this model and I will know you can't bring the whole city in at one time I mean I guess you could try it but I don't think it works very well what I'm gonna do is I'm just I'm gonna find just the area that I'm looking for so for me I'm gonna bring in this area right here this kind of Triangle area and so to do that we're gonna click on the button for the grab tool and one thing that's kind of weird about the grab tool and I don't know if I'm doing something wrong or what but you can't really change the shape of the area that you're grabbing at least on my PC this may be just something that has to do with my installation or something that just has and fixed in a version or something like that so the way that you would situate this instead is you would zoom in or out in order to fit this location and do note that the bigger this is the longer this is going to take the download and generate your buildings especially on a slower internet connection so I'm just gonna pick this area right here and I'm gonna go ahead and I'm gonna click the button for grab so when you click on the button for grab what that's gonna do is that's gonna download that map data from OpenStreetMap and it's gonna generate a city based on that data so that's gonna bring in buildings it's gonna generate roads I believe it's gonna generate some trees and things like that as well so we're gonna let this work for a minute and then we'll come back and take a look at what it did and so you can see how this is going to tell you that it's generating buildings and roads and so when I first fly around in this model you're gonna notice that my camera feels kind of slow and so the reason your camera feels kind of slow is because this is a very large model your camera's not actually slow it's just that you're covering super large distances so you can see how it takes a little while for me to fly around so the first thing you may want to change if you're flying around in this city model is you may want to change your camera speed what you can do by coming up here and clicking on this eye and then clicking on the speed button and selecting the car instead of the bicycle and so if you do that you can see how you can fly around the city a lot faster than you could before and so you'll notice if you fly around that what this is done is this is come in here and it's generated a whole bunch of different buildings based on that map data and it's also in addition to that added in some other things like roads and it's got some trees in here as well and the interesting thing about this at least for me is that these roads and trees and everything like that these all get brought in as individual items you can actually edit and adjust them separately so you can see how I can select this little segment and move it up and down and do things like that and so let's go pick a view that's gonna show us a little bit more you'll notice in areas like this one you also pick up things that are designated as like green areas as well so in this case this is picking up like the Capitol building and the square around the Capitol building but and you'll notice you're getting a little bit of z-fighting in here which means that you've got two planes occupying the same space that's a little bit odd to me but we'll talk about one quick way to fix that at least in your rendered images it gets a little bit more complicated in your videos alright and so you can come back in here and add in more context using this this location function again if you wanted to however that gets a little bit weird because it just brings it in as a new item in your outliner over here so if you do that it just drops it at the same point it doesn't position it or check to see if anything's overlapped or anything like that so my recommendation would be to try to pick up everything that you need in your first go-around when you do something like this so if you decide you want to change the color of one building probably what you could do is you could use the eyedropper and then you could come in here and you can add a new material so let's say we wanted like a blue material or something like that and you don't want to just click in here and add that and so if you wanted to replace the material on all the buildings you would just make sure that the replace material function was selected and that would replace that material that's being applied to all of those buildings or you could turn on apply to object mode and you could just apply it to one building by clicking and dragging it in here like this and you can see how it's acting a little bit weird but you can definitely use that to do this it may just take a little bit of extra moving around in order to really get the look that you're going for so that's kind of the buildings now let's take a look at the roads that this brings in so this brings in the roads and an interesting thing about the roads is it actually brings those roads in as individual objects so you can see how I can click on one of these roads and move it up and down which is probably a good thing because it just kind of like stacks them all on top of each other so being able to edit that is probably a good idea but those roads are in here is individual items and so one thing you can do is you could replace the asphalt material on all the roads just by going in here and using replace material so if you decide that you wanted to use like a man-made ground material maybe like a concrete road or something like that you could drag that in so that all of these roads get replaced with that material if you want or you could also come in here and you could use apply to object mode and just apply that to individual little roads just like this and so one thing you might notice about this that gets a little bit odd is when you do that you start running into what's known as z-fighting which means that a which means that you have two different materials in one location and the graphics engine is trying to figure out which one to display so this kind of flashes and so what that means is you start running into this weird effect inside of your renderings and so you're gonna run into this at two different levels you're gonna run into it at the level where your roads are overlapping so you're also gonna run into this from an overall level so if you see how if i zoom out you're getting this z-fighting really bad off in the distance because this is trying to figure out if it wants to display this giant ground plane or if it wants to display this grass and these roads and so that doesn't look very good and the best way I've found in order to fix that is to just select your ground plane and just use the up and down and move it down by something like negative 0.2 or something like that you can see if I move this down to negative point two all of a sudden I'm not getting that z-fighting anymore because they're not they're not operating in the same 3d space so you can use this in order to in order to fix that z-fighting and all you've really done is you've just moved your ground plane down so it's actually slightly below the road geometry itself and you have to be a little bit careful you may want to consider like putting a curb along that or figuring something out to kind of cover that or just use your camera angle in order to hide it but that's the easiest way I've found to fix the z-fighting inside of this model if anybody else has a better way let me know but the other way you're gonna have to deal with that is you're gonna have to deal with that on an individual roads overlapping level but for like individual roads like this one so if you're going to have like this little strip right here I would probably actually just delete so if I click on this I'd probably just delete that but you can see how you're still getting that right in here so probably what I would do is I would take this little stretch of road here and just move it up by something like 0.1 so just enough that they're not occupying the same space anymore now you're not getting the z-fighting that you were getting before and so applications like this one are a good place and I'm gonna make a full video about this function but applications like this one are a good place where you can use the copy objects function so let's say you were coming in here with your library and you're trying to add city furniture material and let's say you wanted to add some benches in here so let's say you wanted to add a few of these Teague fig benches you could add one in here like this and we'll go ahead and flip it so we'll just type in 180 degrees well now if you remember if you have an object selected you can hold the shift key and click and drag along an axis to create a copy and so then it'll ask how many copies you want to create and so you could create two or three copies and adjust the spacing in here as well so if I hit OK what that did is that created multiple different copies of this bench in here and so this is really good for urban applications because everything kind of has a fixed spacing so if you're trying to like randomly place things or something like that that can get a little bit weirder there are tools for that but for something like this being able to copy things in a straight line is really helpful and then the last thing I want to talk about and we may get a little further in depth in the city building a little ways down the road but I want to talk just for a second about some of the decals that you can add in here so I'm gonna do a search for decal and click on that right here and we probably want to go back up into our library before we do that but you can see how there's decals contained inside of twin motion that you can use in order to add things like striping and other things like that so you can see how this decal you can adjust the sizing on it just like this and then you can use the copy function and create a bunch of copies and so you could actually use these decals to create things like Road striping and other things like that so you could also come in here and add like puddles or other things these details basically sit on top of objects so you could bring in like a right turn arrow and drop that right here so you can use those decals to make your roads look a lot more realistic whoops which is a great function for being able to add these different things in here without actually having to adjust the geometry of the road itself so coupling the decals and the object placement options and the road materials in here can allow you to really quickly create roads and cities and things like that so that's Harmon in this video leave a comment below let me know what you thought you have any tips for city modeling inside of twin motion that's a lot of having that conversation at you guys if you like this video please remember to click that like button down below if you're new around here remember to click that subscribe button for new rendering content every week as always thank you so much taking the time to watch this I really appreciate it not we'll catch you in the next video thanks guys
