couple more questions: 1) if imported geo does not already have UV's, will UVproject create a new set or does it require them to...replace them ?
2) if you've imported an obj sequence with UV's already on (for an animated, deformable piece of geo)... and your using a static camera (say a single frame of your shot camera)... is there a way to do something akin to Maya's "texture reference object" whereby the UV's are changed based on this static camera, for all the subsequent frames of the obj sequence ? ..sorry if I'm too verbose...that was sort of a stream of consciousness question. Basically I'm asking if there is an easier way then my current method where I export an obj sequence with UV's, project3D on a single frame, render with scanline to unwrapped UV, then input that into the full obj sequence to get my "paint" to stick throughout. oy, sorry again.
