Thanks jiminy I've tried that and there's a couple of problems there:
As I jump between scenes, the matched photo appears before the model rotates to the right position and obscures the model to the viewer so it's hard to Understand what is going on (is there a way for the matched photo to appear later?) When I try to export to, say, pdf 3d, I can't find away to export it without losing the matched photo.Will appreciate any ideas
