View Full Version : Incident angle buffer?

Is there a way to render out all my full color images, and also render out an incident angle buffer for every image?

I could get what I want myself if I surfaced every object with a black to white gradient on the incident angle, and cranked the luminance/ziltched the diffuse/spec. But I dont really want to have to resurfce everything and rerender. If gradient can see the incident angle, cant I just pump it out automatically?

I played around a little bit with RPFs and the normal buffer, but that gives me a psychedelic party in After Effects, which while groovy, is not what I'm looking for.

Any help would be appreciated.
