Your original post says future updates: Occlusion Culling. Is this not yet implemented yet? I dont think a culling system is worth considering unless it implements Occulision Culling as roblox handles everything else reasonably well.
With the addition of Occlusion Culling being an official part of the Roblox renderer in the near future, the Occlusion Culling method present in Unicorn VisTools sweet will be retired.
