Hi Ed, I updated the SeparateOBJ program to also emit material IDs - these are "usemtl" statements in the OBJ file.

Maybe this will be enough to enable assigning different materials in HyperShot, could you please give it a try?

You can download the new SeparateOBJ program from here: http://moi3d.com/download/SeparateOBJ.zip
