After popping messages to many of the folks around here for various things, I decided to delegate a single thread for my various probs and proposals. Therefore avoiding the many threads I would end up creating, for a lot of the ideas and art questions as I dive into TDM more.
So the first one up that sorta hit me as I was editing tonight in Dark Radiant was terrain. Now I'm fairly impressed with what the patch system can do but I have concerns with blending textures. Currently as far as I can tell, decals are limited only to actual brushes (not patches). And secondly, patches from my knowledge don't have any kind of paint mode. So I guess my other option would be modeled terrain, which actually seems easier for me. Only thing is if id 4 actually supports the method I want to use, which is vertex painting.
I'm assuming that you can edit vertex colors and that they're probably preserved in the engine. But what I'm wondering is if the engine supports multiple textures being painted onto the same mesh? For painted terrain and so forth. Part of me feels like you should be able to assign three different texture layers in the shader via RGB colors, (which would be awesome!) because then I could have grass, dirt and gravel properly blending on the same mesh. I know that's something I would be able to do with Unreal, and in Source you could just paint onto displacements. So now I'm just trying to figure out the best method for accomplishing that in TDM. Many thanks in advance!
