Hey, looks cool! Thanks!
I noticed some voxel space aliasing though, I mean the lighting doesn’t change smoothly when you move things. Maybe these settings will help:
r.VXGI.HighQualityEmittanceDownsamplingEnable = 1
Material: VxgiProportionalEmittance = 1
Material: VxgiCoverageSupersampling = 1 OR MaterialSamplingRate > 1
