Regarding BatchRendererGroup (BRG); there is a method to set the global bounds BatchRendererGroup.SetGlobalBounds(Bounds bounds) and the documentation states it would be used internally for culling. This seems not to be working though? At least for frustum culling? Is that right? I could make frustum culling work by implementing an AABB frustum check manually in OnPerformCulling but should I have to? Also the global bounds seem not to be accessible, so I have to cache them manually as well? I find the BRG documentation a bit lacking. Has someone a pointer to some resources where I can learn more about good practice when it comes to using BRG?
