"Build Geometry" breaks level textures

I’m running into an issue that when I build my level geometry (either during a build or manually in the Build dropdown menu) it breaks the floor texture and lighting information for the scene.

  1. I don’t receive any related errors as far as I can tell.
  2. The level was created in Blender and textured in UE with megascan assets. It is one static mesh, combined in Blender.
  3. It is not a landscape actor as it is an imported SM.
  4. Duplicating the level or project does nothing.

Any help is appreciated! Working on a school final, so time is of the essence!
