Troubles with texture Atlas

Using texture atlas to combined objects for unwrapping into a common uv map. I add all objects to the texure atlas group. And can manually unwrap using the Start Maunal Unwrap button. When I click FinishManual Unwrap button, I get following error and the Properties menu view switches to a 3D View.

It only does this on the wings. Anyone have any ideas??


Help please?

Could you share us .blend?

Resolved the issue by deleting the offending object.

ends up like this.
I have the exact same issue have not been able to solve what do you mean you solved it by “deleting the offending object”?
