Hi sherriwerner,

The error message with the 3DS feature (in the 3D Workshop) is related with certain 3DS objects and the way they were developed (before Punch)
3DS objects are defined by polygons structures called meshes and not all these polygons can be imported in Punch
So the secret is a change in the polygons morphology.
I did a tutorial describing how I do this morphology change
