The problem is that the uv array needs to be marked as "Texture" attribute for the PointData. You can write a PythonProgrammableFilter which generate an output with the Texture coords setup correctly. Let me know if you need help with that. Also remember this filter will have to combine the two "u" and "v" arrays produced by vtkTableToPoints into a single array with 2 components.
