Hey, Hoofd --

I'd suspected as much.  Unfortunately, on this particular geometry, the option to smooth edges is greyed out.   In fact, all options under "model" are greyed out except "Transform."

I've fixed the geometry by opening it in the vertex modeler, converting it to the primitive modeler, then reconverting it to the Vertex.  The "creased" edges stayed creased, but by triangulating the geometry, it's no longer enough of a crease to render as a line in toon!pro.  Unfortunately, the model no longer is a conforming model, so I had to take it into Poser and redo the setup.

Painful, to be sure, but worth it, since this guy is one of the main characters in my current project.

Thanks for verifying my suspicion about the color of the edges!
