Projected textures or 3D texture placement on NURBS
Projected textures or 3D texture placement on NURBS surfaces may not reflect the correct placement in the views after you transform the shapes.
Mapped 3D texture on polygonal object
If a polygonal object has a mapped 3D texture then hardware texturing requires that the surface have a regular grid of unique UVs between 0 and 1 for sampling the texture over the surface.
Default texture resolution issues
Default texture resolution issues (which can be modified by switching quality in the material’s Attribute Editor) include the following limitations:
