What's the use of this function? What it does is something similar to reflection, but how can it be used? I thought you could utilize it for faking reflections, but how?

A good way to use it is to render reflective materials with environment maps only. Then in comp, you multiply your environment reflection pass by the reflective occlusion pass. It works pretty well if you've got shiny objects in your scene and don't want to do full-blown glossy reflections.

Sounds interesting. I guess it comes with limitations? What information goes inside of reflection pass, i.e outside (white) we have reflected environment, and what's inside (black)?
So we need to render 3 times: one all our main passes, then reflection occlusion pass, and then environment reflection, correct?

heres a quick tutorial on it. for animation i would swear by it :buttrock: . it can it done in camera so u dont need to render out so many passes but yes it gets multed by the enviro pass.
