Cave Lighting - Utilizing the Position Pass

This is an experiment projecting an animated noise onto CG geometry using a position pass layer, simulating light spill on the rock wall. Then using that light projection to generate the light beams/god rays.

I wanted to keep the modeling and CG set up fairly basic, focusing on the outlined lighting technique and composite. The cave was modeled and textured in Blender using some rock textured brushes, and composited in Nuke.
