UV Faces invisible

My doors have nothing showing where the main face should be. Every other mesh I import is fine using my workflow;
Blender unwrap with smart-project over two channels. You are looking at channel one in the attached image. What did I do wrong?

Go to blender, go to Edit mode of your mesh, double tap A to select whole mesh, press Ctrl+N to recalculate normals :slight_smile:

Thank you Ligazetom!

That works a treat. I clearly have quite a bit of learning to do with UV’s.

Appreciate you taking the time to help out a newb.
