I think so. When I import the orginal OBJ - I do so in a way that doesn't show the groups. If I subdivide and then export out - then the CR2 picks it up and the subdivide shows. But the part I add is not really part of a group - i get that.

So, if I import it into Blender in such a way that all groupings are shown - I add the mesh to the CHEST group - SELECT ALL and re-export it. When I do that - NOTHING shows when adding the CR2 to the scene.

Something is missing......for sure.
