Renders ambient occlusion based on world position and normal passes. (And camera, optionally)
Especially handy for those huge, complex scenes where occlusion out of 3D packages would take forever to render.
This is the first plugin I've written for Nuke and it has some stability issues. But it still is very usable already if you just save regularly and prerender its output.
