How do I fix the UVs on this propane tank? So I was trying to find a way to convert an FBX file from ASCII FBX to Binary FBX and when I converted it this happened and I did some research and found out that it was that the UVs were messed up. I'm very much a noob when it comes to Blender and I have no idea what those are and how to fix this. Is there anyone that could help me?
That is actually an issue with the normals of you mesh, which is the direction the faces are pointing/facing. You can recalculate the normals by selecting all of the mesh in edit mode and pressing Ctrl+N. This could be resulting from double vertices, so you could try removing doubles with W, again in edit mode with all selected. This may affect the exported file (assuming you are exporting it) in an undesirable way, so just be careful and have a backup.
