Hey guys, got a question, i used to know how to do this but i completely forgot, i have a tree and one uv set for the trunk and one for the leaves, i want to apply the two different diffuse textures i have in one material and have them respect their uv coords and not "overlap" each other, i cant remember how, i know it's…
I don't completely understand what your trying to do.. Sounds like just having multiple material IDs like DeadlyFreeze said.. Just remember about multiple material ID's use an additional draw call for that mesh.
2 mateiral ID's and 2 materials in udk would be the normal. way, but it is also possible to do it with 1 materail, and multiple UV sets, too. But that is a big hack, anbd also requires vert colour as a mask.
