So the standard setting is:
r.Lumen.MaxTraceDistance = “10000.0”
changing that value will solve the issue with the limited reflection distance.
The other problem I could kind of solve by changing the proxy triangle percent in the mesh settings. This is not a great solution since its causing a huge performance drop with highpoly meshes.
So. I was wondering why my interior is looking very bright and flat. After checking everything I could think of I found out that the Lumen Scene view is looking very broken. Is there any console command I could try or do I have to do something different with my meshes?
