issues with surfaces ue4

I created an .fbj mesh on blender and imported it to ue4. When i try to add a surface imported from quixel this happens. What should i do?

UVs, I guess. Select the mesh in Blender, Edit Mode, Select All (A), U, Unwrap.

This definitely looks like you’re missing UVs on this mesh. Be sure you add them prior to exporting to Unreal.
