 |
|
Hello,
I've imported a polygon mesh into UV layout and I'm getting a warning that says "11 odd polys moved from UV space into ED space." What does UV layout consider an odd poly? In Maya (where I built the model) it says I have no N-gons and I have more than 11 triangles in the mesh. I've also checked that I don't have any flipped normals, so I'm a little confused as to what I need to do to fix this. Thanks! |

Something I forgot to mention, I have also checked the mesh for non-manifold geometry. As far as I'm aware my mesh should have
- no n-gons
- no flipped normals
- no non-manifold geometry.
I've attached the file I'm having issues with if that's of any help. |

"Odd polys" are ones with zero UV area.
Your original UVs are a planar projection, and so some of the side wall polys are perfectly edge on in UV space, so have no area. Because UVLayout's main goal is to give every poly the same relative amount of texture space, these zero area polys are considered to be a mistake, so are detached back into ED space so you can deal with them properly.
The only way to avoid this splitting up of the mesh is to load it with "New" selected, and then your existing UVs are thrown away.
