I have watched the video for multipass rendering in the ‘artist in action’ tutorial. The tutorial was made for zbrush 4, not 4r2. When I try and render out an animation of just the occlusion or shadow pass (flat shader and selected shadow or AO in the BPR settings) the render comes up with only the flat shader and now other shadow or occlusion information. It is visible in the still frames under render passes, but I am looking for the animation itself. Zbrush 4 seems to work fine, but since R2 files are not backwards compatible, I seem to be at a loss. Has anyone found a solution to this problem.
