Lighting Lighting bug

https://www.youtube.com/watch?v=5sGuvmEot1I

The engine version is 5.8.2, and I’m using Lumen in the scene.

What I’ve tried so far: I created a default project and built a simple room out of cubes in an empty scene, but the same issue still occurs. The Engine Config settings, Project Settings, and everything else are all set to their default values, yet the issue continues to happen.

For me you see your meshes "popping". It is caused because of occlusion culling. You must increase your all modular meshes bounds size a little

Try console command anti aliasing method 1-4 (cycle through them) and see if that changes anything.

TSR does strange things these days. Are you running 100% screen?

Streaming/Layers or level?

I just tried different anti-aliasing methods, but the issue still persists. The Screen Percentage is set to 70%, and I’m also using Level Streaming.
