I've just finished a complicated model of a cutaway of a house. My client was wondering if it would be possible for him to manipulate the model in Photoshop CS 3 Extended. As an experiment I tried it, but had problems. When saved out of Strata as Collada- the model came in as a black and white simple slab. When I saved it as OBJ the entire model came in, but without any textures or color. What procedure should I use to bring a model into Photoshop and the manipulate it?
