say ive got a heightmap and there is definite walls (or cliffs) in it, is there a way to spread the texture evenly across all surfaces as aposed to just say y planar wrapping it? (which stretches the altitude changes)
hmm, only solution i thought was to craft the uv map instead of the model first, then go backwards... sounds like an interesting way to do modelling... call it "origami"
There were a interesting solution using cubemaps in 2004, but I havent seen many develoeprs using it.
Currently most talked about non UVW method seems to be PTEX.http://ptex.us/
