Hello there @dh00me19888!

From your provided screenshots, those smudges have appeared in other threads in the community, they are usually tied to Nanite not interacting properly with certain meshes. Open the affected assets in editor, and test disabling Nanite Support for them.

If that is not the case, to rule out pre-existing elements on your system, please update your OS to the latest version, and update your video drivers to the Developer version (pick the “Clean Install” option if available).

In case the problem remains active after those actions, there are more options to test:

  • Switch between FXAA and TSR
  • Alternate between DX11 and DX12
  • If you re using Virtual Shadow Maps, disable them, and test with traditional shadows or ray traced shadows instead (do the opposite if your setup’s the other way around)
  • Choose fixed LOD levels, or test each level one by one, to see if one of them is generating the problem

thank you for replay .
