[LVL ED] Primitives working with occlusion culling

[Adrianis]

Im in a position where, to create a convincing enough environment Im using Primatives with textures to make up walls, instead of static object. There doesnt seem to be a way that I can find to make primatives cast shadow (although there is a setting for primatives called 'cast shadow') for, say, spot lights. That can be designed around, but it got me worried that the occlusion culling wouldnt work properly

I was wondering if anyone knows whether primatives that effectively block the players sight actually work with the occlusion culling system, in the same way that static objects like proper walls do?
