Thanks Kewl, it's really the inside Vuo stuff that I'm thinking about, how one would capture a 3d scene to wrap a cube without weird distortions and misalignments.
Would you build a kind of 6 camera setup? and how would that stitch together? What if the room wasn't perfectly cubed? Could we maybe stitch two 180degree fisheye cameras together and somehow use that to build the texture map?
Looks like I almost got there, omitting the get tree content node feels like its made it a little faster. I wonder if I could get better results if the coordinates were listed in a different way so we don't have to have so many processed list nodes. Will report back. Thanks again for the quick response!
