I am trying to create a script that randomly put values in bend,twist,side-side. It works except for one slight problem, Twist doesn't seem to want to work. I am currently writing it as:

scene = poser.Scene()
figure = scene.CurrentFigure()

p1 = figure.Actor("Chest").Parameter("Twist").SetValue(2) 

I tried this in the PoserPython Shell. If I did bend or side-side, it works. For twisting, it doesn't. Am I writing this wrong?
