Does team Unity have something similar to UE5’s Lumen or some sort of inbuilt voxel cone tracing feature planned for the Unity roadmap? We have seen examples like SEGI’s voxel GI implementation that generate dynamic local GI with no baking at all.
Something like this that supports real-time GI would be amazing.

We’re stuck with an outdated version of Enlighten until 2026. That of course is, if it doesn’t get randomly thrown out again, which could happen at any moment.

I see. VXGI wouldn’t conflict with Enlighten though. The only reason I’m not using SEGI’s version is because I can’t have Unity builds with SEGI due to an error in it. VXGI simply overrides the lightbake data on the screen just like how SSR does. So while they might not update light baking, they can still implement a voxel based GI without having to upgrade Enlighten.
That’s pretty awesome.
It’s worth noting that this likely won’t be released publicly:

Just another showing off.

Speaking of examples I thought I would search the forums and github for existing solutions and below are the initial results ordered by age.

One of their posts mentions it’s running on an iMac too which suggests performance should be better than Lumen.
