[vtkusers] Using multile texture files in vtkOBJImporter

[Ken Martin]

Your example should have an OBJ with multiple textures if there is no more
than one texture per material.

If the issue is that you have an OBJ file where one piece (material?), uses
multiple textures and has multiple sets of texture coordinates per vertex,
that is not fully supported.  I believe currently the multiple sets of
texture coordinates are read in but only the first texture map and
coordinate are used but I may be out of date.
