Join Adam Crespi for an in-depth discussion in this video Painting specular and transparent textures, part of Creating Game Environments in Maya and Photoshop.
My diffuse image is shaping up nicely, and now I'm ready to think about the…specularity and transparency for my gas station.…I need a couple of different things here to bring it across to game.…I've got a diffuse map and a normal map going.…I need to add in a Specular channel in some place and also define my transparency.…I'll take a look in Unity and see what I need to make, then go back to Photoshop…and see what I need to do.…I've got Unity opened in a completely blank project.…I haven't imported in any of the packages for controllers.…I'm going to make a new material just to look at what it needs here.…
I'll choose Create > Material.…The default material is just to diffuse;…all it has is an RGB base.…I've got a couple of different things I'm going to need.…The first is a Bumped Specular, and this'll help me on the walls, doors, et cetera.…So what I'll do is in the Alpha Channel, put the specularity.…What we can see here is that in the base RGB is the color and the glossiness is…in the Alpha, then I've got a separate slot here for a normal map.…
