IT EVEN WORKS IN REAL TIME WITH PHYSICS. I don't know if any game engine out there has something similar to this right now. This is nuts.

Roblox's occlusion culling is so mesmerizing to look at in wireframe mode. It just works... and it's instantaneous too. This is incredible technology.

Every single modern game engine has had something like this for years now. Or even more complex.

i wonder what the overhead is on this, is it really just free fps for even the lowest performing devices?

Unreal and most internal engines at large publishers do this. Ubisoft since ~AC Unity (2014) as far as I remember. Unreal as part of nanite. here is a 2015 SIGGRAPH talk which explains the technique among others, though modern variants are different.

Hey! Thanks for correcting me on this. I definitely jumped the gun a little and assumed everyone was still baking things.

roblox has trapped a wizard in their hq and is forcing them to perform miracles

I really hope they give a talk on this, I'm interested in knowing the details and how its so performant to be ran on every frame. I'm guessing heavy use of axis aligned bounding boxs?

Awesome!

oh you updated to windows 11

Most of them do

Good
