Using the stitch tool

- [Instructor] Now that we've got our UV map pretty much laid out, let's add that test texture and see how it looks. So once again, I'm going to grab this corner here and drag down and create a new window. And then I'll change that window to a shader editor here. I'll hit the N key to close that panel and now we should create a new material for this. If we come over her to the Materials panel right there, you can see there's no material. And also you can see there's no material up here. So let's go ahead and do that. I'll click New. And for this, let's call this Building 1. Right, that's the name of the building over here. You can now create a new image texture node with Shift + A, Texture, Image Texture and I'll drop that right here. Now, to create that UV test texture, let's just click New, and I will call it UV Test Texture. And let's change the generated type to UV Grid and click OK. All right, so there we have it. I'll drag the color over here to the base color. And there it is. All right, it's looking pretty good actually. We've got the checker pattern pretty much the same size here all the way around and that's good. That's what we want. Now, one consideration I do have is this corner. If I bring back a couple of the buildings, you can see that the ally is going this way and generally speaking, I think I'm going to be viewing this ally from this direction. So what's happening on this corner right up front by the camera is actually pretty important. So let me hide these again. And currently, what we have here, let me come down here and I'll hit the L key right here, if I hit the G key and move this around, you can see that as I move it around, that texture isn't consistent around that corner. Now, I can place this pretty well, I can line it up so it matches the edges of the front UV island. But still, I think I'd like to have a seamless texture going around that corner just to make sure everything is lined up properly. To do that right, what I ought to do is reconnect these two UV islands back up. So I initially created a seam there but what I'd like to do now is join these back together. To do that, we can use the stitch tool. If I go to Edge mode, and I click Alt and I click this edge right here, the other one is also selected because we're in this Keep in Sync mode. So if I select this, then this edge over here is selected and if this edge over here is selected, then this edge here on the left is also selected because it's all the same edge. What I want to do is just unclick this. I'm going to turn that off and then I'm going to hit the A key over here in the 3D view and when I select all of it, then I'll be able to see all of the UV islands here. Now if I come in in edge mode right here, and press Alt and click this edge, now this is the only edge selected. We aren't keeping in sync here between the 3D and the UV map. So I can select this edge and Alt + Shift + click this edge separately. Now what I want to do is tell Blender to stitch those two edges together and to do that, I can come over here to UV and right here is Stich. So if I click this, now I've got this green thing happening, the edges are green and way down here at the bottom, you can see we've got Mode, Edge and Tab. If I press Tab, it changes to Vertex mode and it tries to find all the vertices that are shared among that edge. You can see there's a few over here. And it's trying to connect those edges up. That top trim is connected there so you can see kind of a ghost image of what will happen if we use Vertex mode and that's not really what we want. So I'm going to hit the Tab key again to get out of that. And you can see a snap is on which is good. Mid points is off and if I hit the M key, I can turn that on and you can see that this is what's going to happen. It's going to connect these two in the middle of those two edges. I'll hit M and turn that off. You can see that here. I can also switch which island is going to move to connect up. So currently, the edge of this island is going to move toward the front and connect up there. I could hit the I key and switch it so this side is going to move over. But I think I want this right here. So with all this set up now, and I really haven't changed much at all, the defaults are usually pretty good here. All I've got to do is just click. And now those two UV islands are connected. So if I come back here to Island mode, click that and then click in this island, it'll select that entire thing now because it's all one island. And if I hit G, you can see the texture moves all at once. So we're around that edge. So there's a seamless connection or a seamless texture over that edge and that's what I wanted. I wanted to make sure that any texture I put on there which'll probably be a brick texture will be seamless across that corner. All right, so now that I have that the way I want it there, I think I'm ready to export this out so that we can take into Krita. To do that, of course, I need to hit the A key over here to select everything. And then I'm going to click UV and go to Export UV Layout. And let's take it over into our Textures folder. Down here at the bottom, I'm going to change 1024, I'm going to change this to 2048 so it's two K. So it's twice as big. There we go and then let's call this Building 01 UVs. And there it goes. All right, let's go open it up in Krita. Here in Krita, I'll go to File and Open and I'll browse to my Textures folder and here we go, here's my Building 01 UVs right there. I'll click Open. And there we are. I'll change the name here to UVs for that layer and now let's go see if we can find a few textures for this. Here at the Blender Cloud at cloud.blender.org, I've gone to the Libraries and I'll click on Textures and in here, there is some brick. So let's take a look at these. See what we want from this. Oh yeah, see, there's a lot of good brick in here. Right here, that's pretty nice. I'll go ahead and grab that. And I'll put it in my Textures. Let's go back see what else we can find. There's quite a bit here. I kind of like this here. I'll grab that, that's a 4096 texture. That's four K, that's pretty good and they've got a lot of other things like specular and bump and things like that but I think all I really want is just the color for now. I'll grab that. And let's get more to try too. How about something like this? And I'll download that. And once again, all these textures will be part of the project files so that you can just grab them out of the Textures folder or you can come here to the Blender Cloud and grab some different ones. All right, so let's go back to Krita and in the next video, let's bring some of those textures in and begin placing them here on the UV map.
