I've been messing with the UV Project modifier. This appears to require a UV map to be present for a mesh. Unfortunately, sculpting with dynamic topology activated removes vertex data such as UV maps.
Is there some way to project (perhaps in world or generated space) one or more images onto a mesh during DynoTopo sculpting? Optimally, I'd like to be able to project multiple images a la UV Project but I'll take what I can get.
