Stripes on walls and floor UE5.1

Hello.

I’m getting this weird stripes on walls and floor when the camera on certain angle and distance.

The stripes only appears when path tracing mode is turned on. No stripes in lit mode and game mode.

Stripes appears on rendered image sequence from Movie Render Queue too.

What I’ve tried but doesn’t work:

  1. Increased Shadow Bias on light (scene only got one light)
  2. Switched from Virtual Shadow Maps to Shadow Maps
  3. Build lighting (multiple times)

Does anyone know how to fix this?


Please help. Thank you.

I am having same problem. I can’t find a solution anywhere.
