I want to be able to maintain the ability to auto orient my camerawhen rotating around 3D layers, but if I go over the to of the layers the camerabecomes righted instead of staying upsidedown. Is there a way to have the camerastay looking at the point of interest without it always flipping right side up? I could see it would be possible to build an expression that can change the Z orientation if the values of the Y and Z are more/less than certain values, but it's possible that there is an easier way I can't think of.
You need to m,ake a 3D camera rig using nulls. The problem goes away.
Just google "3d camera rig creative cow" to find the how-to info.
