i'd like to see the uv map while texture-painting. But the uv map in the uv editor shows only if the 3d view is in edit mode. I've seen in a tutorial that the map can also be visible in texture paint mode, how can i do this?
If you switch back to BI then select texture paint, then you can go back to cycles to paint and the outlines should stay. I think it is a bug because it turns off sometimes until you switch back and forth again.
It looks like this has been added in 2.71, but I don't see it in the release notes.
