In this lesson we'll learn how the decals were added to our robot, which helps tie it visually to our truck model. All right. At this point, we're going to go ahead and begin projecting on the decals, or the graphics, that were on the truck that are going to make this robot recognizable as basically a modified version of the truck-- or a transformed version of the truck. Now as opposed to using the layered-painting unproject and project workflow that we used in the truck texturing course, in this course we've already got all those graphics that we created. I'm actually going to just go ahead and use this decals.psd file. You'll find it over in your images folder. And we're going to use this particular Photoshop file to actually paint through and apply these different graphics to the robot itself. Let's talk here for just a moment about the location of these graphics. Now when it comes to the location here, one might think that well, I need these to be in exactly the right location-- the precise location-- so that when this robot is transforming into the truck, the pieces on his body that have these decals end up in the exact position where those decals are at on the truck. Well, quite simply, that's just not the case. I've looked over [? Delano's ?] shoulder as he's working on the animation for this transformation, and really, there's a lot of smoke and mirrors involved there. That transformation happens quickly, that there's no way you could ever possibly follow one of these graphics from the robot version all the way to the truck version, and tell that it was in a different location or not ending up in the correct location. My concern here is that these decals, not only are they applied, but they are applied in an aesthetically-pleasing fashion. We want these to look good on a robot-- look like they belong there. I'm looking again at this graphic. Thinking about-- let's just look at this HD banner right here. These two graphics were on the fenders of the truck, on the front side. I want to actually put these right here on these shoulder pieces. Let me just go ahead and zoom in here. And I'll go ahead and jump to Face mode using my Lasso tool here to select some of these triangles here-- right there on the front of that shorter piece. Now if we look at that here, there's a little bit of a dent right here on the bottom-left corner of that. But the important part of this, up here, it's flat. This is where I want to apply this graphic. I'll just zoom in here. Let's go ahead and grab our Paint Through tool, drag our image over here, and I want to shrink that down quite a bit. It's actually a pretty large image. There we go. And let's just go ahead and rotate this into position here. Now I'm looking for some visual markers here on this surface, to kind of queue myself as far as where I want this graphic to extend to. I'm looking here at this corner right here and this corner right here as possible markers. But this one's a little higher. I think I like this one, because it'll allow my graphic to be larger. Let's go ahead and use it. We'll just go ahead and jump this up. Again, we can shift minus sign to reduce the opacity on that if we need to. Hold down the S key to remind myself of where that selection is, and that's just about perfect. Now, the next thing I'm concerned with before I begin painting this, is where this logo's going to end up. I don't want it to end up right there, well, because it's going to get cut off. Let me just go ahead and move this over. Now I'm looking at this corner right here. I want that just inside that corner. Right about there like that. Now, I know that there's a little bit missing there on the side, but we'll handle that here in just a moment. Let me go ahead and actually grab my Hard 100 brush again, jump over and turn off that Flow Control with the pressures, and we'll begin painting that in here. Now again, I'm using the Project On Selected Only mode, so I'm not going to have to worry about painting on any other geometry except for what I had selected here-- used that mode quite a bit when working on this guy. Looks like I got a little bit of this graphic below. Let me erase that. And we'll switch back over to the Paint Through tool. Now let's go ahead and handle this little bit over here. I want there to be black there. We'll just go ahead and move this over. Make sure that type is off of the geometry there. Align that up again. Maybe shrink my brush down a little bit. And I'll just paint that little bit right back in, just like so. I'm going to undo that and bump that up just a little. There we go. That looks better. All right. Again this graphic doesn't have to be exactly what's represented on the vehicle, as long as the important elements are there-- being the logo and the black graphic itself. It's going to be recognized as the exact same visual marker. With that said, let's jump over our Channels pallet, make sure we have our Decals channel selected, not our Images channel. And then we'll bake that down. Then we'll just zoom out and look. I think that's looking really, really nice. What I'd like to do is come over and create the exact same thing on this shoulder over here. Now that graphic, the logo, was on the left side. And if we look over here at the image, we don't have the exact opposite. We've got a little graphic here, but there's not the big, long, black stripe. Well, I think we can still work around that problem. Let's just jump over here, select our geometry, and get that one last little triangle there. Maybe rotate that around some, grab our Paint Through tool again. And let's just make sure we have this the right size first, aligning that up. Let's increase it just a bit, maybe rotate it a little. There we go. Let's close. Now let's get the logo in the right spot. I'll just drag this over here like so and paint in the logo itself. All right. Great. Now we just need to move the graphic on over and paint in the black stripe to the left of the logo. Just align that up-- start right about there. I think that that's lined up pretty evenly. Maybe just increase my brush size some so we can do this a little quicker. And great. We can go and bake that down. And just kind of take a look here. I think that's looking great. I think that looks very similar to what we have on the other side. Now I want to show you one problem I ran into when using these graphics. I want to come down here and select this thigh piece, because I want to use it for another graphic that's on that same file. I use my smart selection here-- going to select some of these different pieces. All right, great. Now we'll just go ahead, right click, and hide the unselected geometry. OK, great. And I'm going to quickly do the same thing here. Grab my Lasso tool, select these triangles here, grab my Paint Through tool. And let's say we wanted to use this little graphic right down here. Now if we look at this graphic, this is the one that was on the side of the bed. And there's only one of those. We're going to run into a problem we try and put this on the other side. Let's increase the size of this on up. Rotate it into position here. All right. I think that looks pretty good, and we've got a geometry selected. Let's just go ahead and paint that in. We want it to be the exact same on both sides here. Let me go ahead and just paint that in, bake it down here. Now herein lies the problem. You've got to do the exact same thing on the other side, but we only have this one graphic. We could always come in and remake the graphic, and flip the type to be the exact opposite. But our red stripe is going to be on the back. We want it up here on the front. Let me show you a little trick. I'll just jump over here, and let's go ahead and just select some of this geometry and hide it. Make sure my paint buffer's cleared out. And we'll deselect those triangles, and we'll deselect these two. Great. Now we can go ahead and hide the unselected. Let me go in and undo that. We'll hide the selected, rather. And let's jump over here to our Projection panel. Now if you've watched any of our Mari content before, you know that I'm a big fan of this Back Face mask. If we turn that on and enable our preview, you can see here that the bank faces of these triangles get masked out. We can't actually paint on them. Well, this is a case where I want to be able to paint on these. I want this exact shape, but I don't have it for the opposite side. Let me go ahead and grab this little piece of geometry that wasn't hidden. Hide that really quick. And I'm going to turn off my Back Face Mask. Now, with that done, we're going to paint on the back face-- these two triangles right here. Grab my Paint Through tool again. Increase the size of this a little bit. This is something you might not think about doing, but we can always paint our textures on the back sides of our polygons here. Come in and do that. And if we bake that down and orbit around, you can see there's our edge masking taking over. But our back face masking is right there. But over here on the front side, we've got that exact same graphic, only the type has been reversed here. That's not a big deal. We can definitely fix that. Let me go ahead and turn off this preview here, grab the Paint Through tool again. I'm just going to steal the black off one of these other graphics here. Select my two triangles. We're just going to get rid of that type. We'll bake that now. And now we can come in here and basically repaint in our type. Just get that positioned exactly where we want it and the size that we want it. That looks pretty good to me. We'll just come in and paint in our truck's model number. And we'll bake it down. Showing all here. Great. I've added a few of the decals here to our truck. And again, these decals are really going to strengthen that bond between our robot and our truck, making our robot more believable. Now feel free to add these decals wherever you want to on this robot model. Or if you're actually using a completely different vehicle, feel free to add completely different graphics to your robot, really trying to tie it again to the vehicle that he's transforming from. In the next lesson, we're going to go ahead and move on. And we're going to begin looking at how we can really dirty our robot up with some dirt passes.
In this tutorial we will learn about the process of texturing our transforming robot's robot form. To get started, you should know that this MARI tutorial will focus on providing you with a high level glimpse at the thought processes that went into painting textures for our robot. While we won't focus on painting every stroke of our textures, we will be walking through each step, demonstrating techniques as well as providing insight into the process. This also means that if you use another application for texturing, you’ll still get valuable information from this course in terms of how different texture elements will be identified and layered. This course will begin by focusing on selecting geometry and how MARI’s selection groups can make this much easier. From here we will focus on laying down a base of photographic texture for our robot before moving into adding additional details like dirt, rust and scratches. To wrap this course up, we will learn how to repurpose channels of data for our specular map and then export those maps out of MARI. After completing this course, you'll not only know how the texture maps for our robot were painted but you'll also gain insight into the thought process behind painting them.
