Lumen GI and Reflections feedback thread

[Krzysztof.N]

Is there a way to control the roughness threshold by which lumen decides to trace additional rays?

It’s based on the same threshold as dedicated reflection rays - r.Lumen.Reflection.MaxRoughnessToTrace. In UE-Main it’s now also exposed in PPV.

@jblackwell

Is there a timeline on when the standalone RT effects will be removed? Although I imagine there are still some use cases for RTAO (just wanting occlusion and no bounce for horror games, for example), RTGI is completely useless at this point and actively broken in a project of mine.

The idea is to only remove RTGI and RTR as those should be fully covered by Lumen now.
