Hello,
What is the value of “r.DistanceFields.SupportEvenIfHardwareRayTracingSupported”? If it is 0, can you try changing it to 1? Please note that you cannot change this CVar at runtime - you can change it with the command-line argument“-dpcvars=”r.DistanceFields.SupportEvenIfHardwareRayTracingSupported=1”.
From your logs, we can see you are turning Lumen hardware ray tracing off during the session. Can you please try turning it off at startup with the command-line argument “-dpcvars=”r.Lumen.Reflections.HardwareRayTracing=0,r.Lumen.HardwareRayTracing=0”?
As a test, can you also check if there is a difference between “r.Lumen.TraceMeshSDFs” 0 and 1, with regards to the culled surface cache?
As a test, can you also try setting “r.RayTracing” to false to see if the issue reproduces in that scenario?
