[Studio Beta] Introducing Occlusion Culling

[Kipukii (Kipuki)]

Important to mention that they’re working on dynamic occluders though! Also important to mention that mobile devices and weak computers from 10+ years ago did not have support for the technology.

Here’s a post where Roblox staff discuss this along with why it can’t just be a PC only feature.

Occlusion Culling

We don’t use occlusion culling because hardware occlusion queries are supported only on a small portion of mobile devices. They also have spotty support on older desktop cards. Software rasterizer solutions like in CoD (I believe) won’t work on mobile. Classic methods like portals or PVS require knowledge of the level geometry, involve a lot of preprocessing; and highly dynamic nature of Roblox levels (e.g. any part can move) pretty much precludes their use in Roblox.
