Lumen GI and Reflections feedback thread

question about reflection. In the Matrix scene, the reflection of the buildings looks wired. the nearby buildings’ reflections look great, but it looks wired for buildings that are further away. I was about to try to use “r.Lumen.DiffuseIndirect.MaxMeshSDFTraceDistance”, but it doesn’t work in 5.1. It worked in 5.0 I guess.
Does anyone know how to fix this? Thanks
