[Closed] Dunamic bending based on animation

The Expression and Script Controllers do exactly what you need. They’re very powerful, and well-documented in the help file.

Well you can use flex with the springs on and it will help hold the edge lengths. The other way that I have done it is a bit involved. I use a spring controller on an object to get the dynamics solution and use script controllers on the angle and direction of a bend modifier. The script controllers extract the dynamic objects offset values and work out a solution for the bend angle and direction.
