i had a working room geometry in unity, brought over from maya. with textures aligned on the walls. then i seperated some faces to detach the ceiling, so i could have a different material on it. but bringing it back to unity the texturing was suddenly gone and it appears to be simply vertex-lit now. both the walls and the ceiling do not show any texturing, even when a new shader is applied. i also checked the uv-linking in maya but couldn’t see anything wrong about it. the uv’s are still working in maya.
From the screen shot it looks like the wall and ceiling are still one mesh. Once in a great while I’ll get a problem where an import from Maya will just stop importing properly and it takes a Unity restart to fix the problem.
Another problem I keep accidently running into is I’ll import Surface Shaders from Maya and no textures will show up, even if I try to assign a new Shader to the mesh inside Unity.
Iv’e seen this for Blender as well. It seems as if the 3D apps are being a teensy bit too smart for their own good. When no texture is assigned to a mesh in side the app, it will not export any UVs thinking that they are not needed. The solution should be to simply assign a texture before saving/exporting the mesh.
the strange thing is that it HAD a working textured shader assigned and everything looked right. but somehow the export was still broken.
i just built the same shaders again in maya and assigned them and NOW they work.
