Weird artifacts on the mesh.

Hi everyone, I’m running into an issue here and maybe someone can help me out.
I unwrapped the UVs, used hard edges, and even triangulated the mesh before baking—and I’m using the triangulated mesh in Unreal—but these artifacts keep appearing. Does anyone know what might be causing this?

I baked the maps in Marmoset and am importing the texture into Unreal; the artifacts don’t appear when looking at the normal map in Marmoset, but they do show up when viewing the world-space normal map in Unreal.

thank you!
