Hey ,
I have a question that could possibly be a solution. What does r.Shadow.PerObject actually do in terms of rendering? I have turned that off and was able to crank shadows up to epic without crashing.
Edit: Working settings so far:
r.Shadow.PerObject = “0”
r.ShadowQuality = “5”
r.LightFunctionQuality = “1”
r.Shadow.MaxResolution = “2048”
r.Shadow.DistanceScale = “1”
r.Shadow.RadiusThreshold = “0.03”
r.Shadow.CSM.TransitionScale = “1”
r.Shadow.CSM.MaxCascades = “4”
r.DistanceFieldAO = “1”
