Modifying ScriptFX - I'm using the "Back" easing function Smooth Motion ScriptFX, but the motion doesn't overshoot the final position as much as I'd like.
There is a thread on the StrataCafe on this subject:

Also see the Lua Scripting Forum on the StrataCafe:

And, of course, see the Scripting Documentation which you can access through the Help menu in Design 3D CX.
