This bug was in 2.79 and was fixed, but it seems that is in 2.8 Beta too .

Exact steps for others to reproduce the error

Event Timeline

Brecht Van Lommel (brecht) triaged this task as Confirmed, Medium priority.

Confirmed. Not sure what happened, the code appears to be the same.

Actually I think the unwrapped result is ok, but the ngons are drawn with poor tessellation in the UV editor.

The thing is that. I'm trying to bake a texture from one model to the other. And in Blender 2.79 works flawlessly after you implemented the uv ngon code .
But when I try to do that in 2.8 the bake it's broken by the tessellation errors .
Here is 2.8

Here is in Blender 2.79

Bake diffuse from one model to the other .

Any news on this bug ?
