Why does my model look flat / unshaded?

When your 3D model appears unshaded or 'flat' after importing into Enduvo, it could indicate that the polygons are reversed. Unfortunately, there are no available options within Enduvo to address this. To resolve this issue, the object will need adjustments in a 3D modeling program like Blender to reverse the polygons and display correctly.
