Hi,
I don’t know if it’s possible.
I’m doing a lot tutorials to realize “the perfect unwrap”.
If I use Vray or Octane I don’t care how textures are applied. Mostly I use cubic or planar mapping assigning to several ids.
When we export the geometry into UE4 we have to unwrap everything and check overlapping faces in uv space.
I heard about ptex but this technology is not implemented yet in UE4.
I would like to know if it can help us.
Are there DX/Ogl or hardware limitations?
regards
