I have a mesh that is shaped like a frame. Basically I cut a hole in a plane by selecting knife project in edit mode.
Now I would like to animate this mesh with the help of shape keys. I want to take the four inner vertices and scale them up so they are in the exact same position as the outer ones (effectively making the frame disappear). Scaling itself is not the problem but I cannot figure out a way to scale it just the right amount. Unfortunately I can only manipulate the position values individually (in the pane to the right) but not the scaling. Does anyone know of a way to do this?
Any help would be greatly appreciated!
