(NOT a duplicate post, the only forum post with a similar issue was several years ago with no solution, just a link to a bug tracker. It’s possible this is still a bug, but that was from so long ago that I doubt it a bit.) The artifact occurs in all shadows in the scene, and occurs when moving the camera. This issue did not happen previously and suddenly appeared. Last thing I remember doing before this started was editing the LOD 0 distance of the landscape, but the bug also occurs on static meshes so it isn’t strictly a landscape issue. It is also not an issue in the materials, as it does this on every material when previously did this on none of them. Here is the artifact: [![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/d/a/5dae7802aee811cf445aa82672273e4cfd036a1f.jpeg "UE5 Shading Flicker Artifact") ](https://www.youtube.com/watch?v=AEUm_EKE4EE) Setup: Engine Version: 5.2.1 -26001984 Global Illumination: None Reflection Method: None Lighting: Directional Light and Skylight Shadows: Shadow Maps What I have tried and seen: - Changing global illumination to Lumen removes the artifacts, but I can’t use Lumen for this project as it ruins the art style and several materials completely. - Adjusting exposure and intensities of the light sources do not remove the artifact. Even at super high brightness. - Tried disabling AO in post process settings. Any insight or fixes here? It will be really annoying for players when playing the game so I have to find a fix for this. ---

Also, it seems to only happen on “floors” and not on the walls. ---

Here is another video of the same thing happening to a column mesh: [https://youtu.be/rqdXmMnXpjI](https://youtu.be/rqdXmMnXpjI)
