Lumen GI and Reflections feedback thread

@Yaeko

this issue has nothing to do with the twosided foliage he had to revert… this still is the overshadowing problem that is supposed to be fixed - hence why my trees arent black completely like in another post futerh above.

There were two improvements for foliage over-occlusion:

1. Two Sided shading mode, which I had to revert
2. Reduced Global SDF over-occlusion, which made it in

I’m not aware of any changes that would have made foliage darker in 5.0 release compared to preview 2, other than the two sided shading model thing.

That said, you can tweak just how much the Global SDF over-occludes with:
r.LumenScene.GlobalSDF.UncoveredExpandSurfaceScale
r.LumenScene.GlobalSDF.UncoveredMinStepScale

Those aren’t enough though, there will still be black spots where the Global SDF says ‘fully occluded’ incorrectly. It’s something we have to fix.
