Question about Blender .obj imports

Exported a blender object (a cup) to a .obj file so I could import into UE4. When importing in the editor, I got the message that the object “has degenerate tangent bases which will result in incorrect shading.” Thoughts?

Take a look at this thread: Problem with exporting models - Debugging, Optimization, & Profiling - Epic Developer Community Forums :slight_smile: Probably this will work: "Double click onto your static mesh in the UE4 → Select the recompute tangents/normals and click save "
