Hello
I use UE 5.3.0-Lumen for GI and reflections.

In my mirror:
A - no problem
B - sploches
C - black surfaces
D - light and shadows problems

Can i have helps, please

I have the same question, I was hoping that the new Max Reflection Bounces in the PPV
could solve, but none.

I’m having the same problem. Is there any solution to this problem?

A workaround, not a solution is to place a postprocess volume and only on this room to change the reflection type to hardware deprecated and put 4-5 reflection bounces. Lumen mirror reflections are not there yet.

Same issue here



Things I’ve already done to try to fix this but didn’t work:

  • Try using the previous version UE 5.4
  • Increase the resolution to Cinematic
  • Try using planar reflections
  • Update my video card driver
  • Reinstall Unreal Engine
  • Create a new project
  • Try with a different type of light
  • Fix the normals of the reflected objects and the mirror itself
  • Use the default UE shapes like a cube for the scene
  • Increase the screen percentage to 100% or more
  • Change the materials of the objects and the mirror
  • In GI, increase the “Final Gather Quality”
  • Increase the Lumen Reflections quality
  • Select the “High Quality Translucency Reflections”
  • Increase the Sample Per Pixel of the light
  • Increase the reflection bounces
  • Check “Hit Lighting for Reflections”
  • r.RayTracing.NormalBias 5
  • r.Raytracing.Shadows.EnableTwoSidedGeometry 0
  • r.Lumen.Reflections.MaxRayIntensity 3
