Occlusion Culling ?

Do we have Occlusion culling (or something similar) in RW ?

The question is for red51 of course, but the answer can be usefull for all.

To put it simply, it's a 3D rendering technique that prevents the calculation of objects hidden by others and therefore invisible. It's a way to have better performance. It's useful, among other things, to avoid calculating every small object in the next room, behind the wall.

The underlying question is rather what choice to make to preserve performance in large projects without sacrificing too much the details. If we can "substract" objects inside rooms, that can let more freedom to build.
