Rad.. Thanks for the uber fast support Alexey. Much appreciated. Would be nice if there was an orbit viewport option to always keep bounding box center as the center? Does that make sense? In max you get three orbit modes, for sub-object orbit, or parent orbit or center viewport orbit.. it seems like photoscan is center viewport always, which makes sense, but it makes orbiting around complex selections nearly impossible with heavy files.
Just an idea. In either case, thanks for the quick fix/tip!
