Why Are My Nanite Meshes Causing Unexpected Shadows and Artifacts in UE5?

Hey everyone,

I’m running into a strange issue with Nanite meshes in Unreal Engine 5. In my current scene, certain Nanite-enabled assets are casting odd shadows or creating visual artifacts, especially when viewed from specific angles or distances. I’ve double-checked the LODs, normals, and material settings, but the problem persists.

My questions are:

  • Is this a known limitation or bug with Nanite rendering and shadows?
  • Are there any settings I should tweak (e.g., Virtual Shadow Maps, Distance Field settings, or Light settings) to fix this?
  • Would converting these meshes back to regular static meshes solve the issue, or is there a better workaround?

Any insight would be super helpful — I’d love to keep using Nanite for performance reasons, but these artifacts are making it tough.

Thanks in advance!re
