Why does a lot of the meshes I make do this.

Imgur

Its like faces of the mesh seem to just not import in. I am completely new at this so maybe I am just missing something obvious. I unwrap my UVs like I have read about and scale it up so it is not to small since I am using blender, but am I forgetting anything else that is causing that?

My guess is your normals just face the wrong direction. Recalculate them and see if that fixes your problem.

Thank you very much. That worked perfectly.
