BlurryPixel shows off another feature of the Pixel Cloud plugin for After Effects where you are able to use After Effects native lights to re-light the alpha of an image respecting its depth information.

Pixel Cloud point cloud relighting system for After Effects will allow you to relight scenes in compositing directly in After Effects, inspired from a feature available in Nuke. Check out BlurryPixel for more information on PointCloud and updates as it progresses. Also, check out a demonstration video of Pixel Cloud for After Effects here.

This can be done using an additional position pass or height map pass. Here is a quick little demo of how this can be achieved!
