Proportional editing

Is there a way to have proportional edit mode only affect selected vertices. I want to select an edge loop and use a pretty large proportional edit radius on it, but have it influence only those selected vertices in the edge loop and not unselected neighbors.

And is there a way to save the image of an unwrapped mesh in uv editor, so that that the unwrapped mesh is part of the image. I’ve been taking screenshots and pasting them into photoshop. Which is obviously wrong.

Shift+H to hide everything else works well enough for me, though a little inconvenient at times.

There’s also a little button to affect only connected vertices that comes in handy at times.

And about the second question, use UV’s -> Export UV Layout (in the header).

Thank you.
