Still learning and messing around and can't figure how to do this or if it is possible at all.
Best way to describe what I'm seeing is if you imagine a finger curled tight as the the start point and it out stretched as the end point, rather than uncurling the vertex points seem to mostly trying to straight line to their end point of the shape key rather than maintaining a finger shape and I get shrinking and ballooning as a result.
What I want if for the shape to remain mostly intact rather than 'wither' and collapse while morphing between start and end points. Is there any way to do this?
Thanks for any help!
