Its kind of hard to make a question for this, but I know its very simple answer...
I created model, and I want to edit it, for example add some bent at one point.
How would "release" texture (uv map) from further modifications, and keep it as it is displayed on original model.

Maybe picture can explain better. I added one line and want to manually edit points. But by dragging them, I don't want texture to be dragged as well.
