Lumen GI and Reflections feedback thread

Is there any way to control (in any way, like intensity, radius, contrast, for example) the ‘AO’ generated by Lumen? Previously there was a cvar which was useful to slightly tweak the AO (something like containing ‘bent normals’, but not sure), however it doesn’t work anymore. Anyway, even if still working, any additional cvar related would be useful too.

I assume you mean short range AO which is added on top of GI, and not bent normal from the material output? In that case take a look at r.Lumen.ScreenProbeGather.ShortRangeAO.* CVars, specifically:

• r.Lumen.ScreenProbeGather.ShortRangeAO.MaxMultibounceAlbedo
• r.Lumen.ScreenProbeGather.ShortRangeAO.ScreenSpace.FoliageOcclusionStrength

Where foliage means pixels with a Two Sided Foliage or Subsurface shading models.
