My rendering is weird, is it because of my graphics or because of the engine?

I’m having this weird glitch, where some dark spots on my Fortnite UEFN creative map, it doesn’t look like a shadow, it only apears when in the editor: when the scailability is on the medium preset (all of the other presets don’t have this issue), and when in game: when the graphics are set to Direct X11 epic preset (performance mode doesn’t have this issue). And I don’t know if its the engine’s fault or it’s my graphics card’s fault. Although my map is mostly made up of imported textures, materials, and models. And I also have seen this error in another creative map.

I’m running on a laptop RTX 3050 with Intel 13th gen i5-13420H

(in game the glitch is exactly the same as in the engine when running on Direct X11 epic settings preset)

Looks related to either DFAO or Lightmaps.

Using any of those?

I think @TheKJ is correct. those look like Distance Field Ambien Occlusion. you may be able to mitigate that making sure that your geometry is divided into clean pieces and you don’t have complex meshes.
