EDIT: Seems the command “r.MegaLights.SoftwareRayTracing.Allow 1” fixes this. Now I can use it with a 1000 series.

Keep in mind that SWRT path has pretty bad quality at this point, this is why we have hidden it behind r.MegaLights.SoftwareRayTracing.Allow.

However, since nanite tesselation was introduced, I was expecting light improvements to move in a direction that would make nanite tesselation usable and properly integrated in the light system.

Yes, that’s something we will have to tackle at some point. Unfortunately most ray tracing bits are either inside hardware or driver, so proper solutions take a long time. For now we could bake a better RT proxy indeed.

It’s fixed in UE5-Main, but didn’t make it to 5.5.

Hey, not sure if this is the right place for this, but I have been experimenting in 5.5 and found that enabling MegaLights causes this crash:

If this is with Substrate enabled, then you should post in the Substrate thread. Guys responsible for it are quite responsive and helpful.
