I'm having an issue with a mesh I've been working on where some newly added geometry will not unwrap and texture correctly.
So given this piece of geometry:
I see two strange things happen:
- If I select all connected faces I can see in my UV Editor that the vertices have coordinates of (-nan, 0.000). This seems incorrect/impossible.
- If I try to unwrap the geometry it collapses to a single point in the UV editor (when I would expect to, ya know, look normal). Additionally, if I move that collapsed point around only some of the faces will be textured correctly. Most of them remain unchanged (all faces should be white).
