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)

altitude wrapping?

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” :D

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.
