Drag in a Quixel scan such as any of the mossy rocks. Activate the check box next to fuzzy shading like so:
and you’ll ruin that asset’s materials from then on. It’ll do this weird thing where all the materials look blurry and low quality. You can uncheck fuzzy, close the material without saving, delete the mesh from the viewport, re-add it. It’s useless.
The only thing that brings it back is opening the static mesh. Then all the crisp details come back. But close the static mesh viewer and it goes back to garbage.
