There is flickering shadow bubbles and texture defects only in my mirrors reflections, while the rest of the scene seems ok. All the resolution changes I make in the project settings change the entire scene except the reflections of the mirror.
This problem seems to be affecting a lot of people
I’m using the default settings of the architecture scene.
UE 5.5 version
Geforce RTX 2060 super
Global Illumination: Lumen
Reflections: Lumen
Things I’ve already 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 entire 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”
