Retopology bug

When using retopo mode I can accidentally move vertices/edges of the reference mesh. In addtion moving those subobjects can't be rolled back with undo command.

When the reference object is not selected, how can you move its subobjects? They are not selectable.

Here Is a gif. It takes me few tries to pick one edge, but I finally manage to reproduce it.

What tool were you using when it happened? Was the visual Retopo tool opened.

It happens when using retopo visual tool. Tried to reproduce it without visual tool on, by using tweak_move, but no success so far.

Try this and see if fixed.

I think it's fixed now, no issues so far. Thanks.

Ok, another issue. Now I'm unable to move vertices that are occluded by reference mesh. To move them I have to increase Retopo Z render offset until I see them. I don't recall this to be a default behaviour of the tool.

I would be also really convenient to have ability to increase and decrease Retopo Z render offset using hotkey.

  * A new basic streamline tool, Retopo Z Offset. Drag cursor horizontally or vertically to adjust retopo z offset value.
