Perhaps there is a bug in specific recent versions of OSG, or maybe there was a library version mismatch between their fg and the installed libraries. In any event, I recommend doing a through "make clean", and if that doesn't work, upgrading OSG to SVN. > > Is there any different camera settings that are needed (I am using > camera groups as described in the README.multiscreen with defaults > except for the view. > No.

We were using slave cameras before, so there should be no difference there. It just occurred to me that the order I've assigned to the cameras may be forcing a serialization among all the channels; I'll check it out. >>> I am using the 'CullThreadPerCamera' model, with the gc.realize >>> commented out with the OSG_SERIALIZE_DRAW variable turned off. >>> >>> >> I don't think that's one of the choices :) Do you mean >> "CullThreadPerCameraDrawThreadPerContext"?
