You cannot add 3D textures on a curved surface that contains multiple faces or facets (e.g., swept, freeform, and skin surfaces); if you add a 3D texture to one of these surfaces without multiple faces or facets and then modify the surface so that it has multiple faces or facets, the texture zone is disabled.
