automatic viewport updating when flexing constraining path

[Varchi]

Is there any way to automatically update the viewport as I'm flexing sub-objects of a path to which I have geometry constrained?

 

So far, I can only update the state of the geometry by advancing a frame and back.

Heh, no ideas? Would more details help?

 

I have a series of bones to which boxes are linked to create a repetition of rectangular frames. Along one end of these rectangular frames/bone-chains there is a path to which the IK solvers are linked (at percentage increments equal to the number of rectangular frames).

 

This setup allows me to flex the vertices of the path, which flexes the IK solvers, which bends each frame like arms.

You can imagine the setup looking like caterpillar legs extending vertically from a ground.

 

I simply want the path flexing to live update the arms. To update the arms, I have to advance an animation frame (then regress an animation frame).

Thoughts?

 

I'll post a jpg or avi as soon as I can.
