It avoid having to move away meshes (often. Also the artifacts are kind of located where edges would be added if model was triangulated so my guess it that substance tesselated the model during import, so it’s a bit different of the one you uploaded to Sketchfab (which has quads). Color Generator. Normal Orientation. If all this didn't work, combining the polys and exporting in FBX format will work for sure. The meshes I tested with were UV unwrapped, but use more than one material slot in Maya If I can get this issue out of the way then I can help with some. It sounds like there may be some sort of issue with the mesh geometry. The texture properties are defined as: Black values represent the thin parts of the model.
