Extreme graphical glitches and shadow flickering

Development Rendering

Hi,

I am developing a VR project for a building interior. I am using Unreal 5.4.3 for this project.

I am using Lumen global illumination with virtual shadow maps, and nanite meshes. In my project, the sun and skylight works fine but additional lighting is causing some extreme glitches in the game. I am posting a video of the glitches. Does anybody know why this is happening and how I can fix this?

I had an issue like that as well in VR where a few lights were causing shadow glitches. You could try ’ r.Shadow.Virtual.OnePassProjection 0’. This value disables an optimization so you might get a fps-drop.

Hi, this actually solved the issue. The fps drop was very minimal, but it got the job done. Thank you so much for this!
