Yes. That's the one. On the "Settings" tab, select under "Orientation" select "Photo Up" instead of "World Up". I wish we could exclude the images that don't match into the main clump, but that's not an option right now.
bert, wich editor? where do I have to click? "Edit synth and highlights"?
I also want to know if is possible to remove images from synths, sometimes I see a image that didn't fit in any 3d group so I want to remove it and make my synths more synthys! :D
