dynamic constraint question

[Invictus]

Despite being inspired by the Tech Talks presentation on dynamic constraints, I am unable to reproduce any of the effects there with v13. Please correct me if I am missing a critical step or two:

1. I make a chain of three bones inside a simple tube of CPs. I assign the CPs to the bones.

2. I open an action with this model.

3. I translate the top bone back and forth in a couple of keyframes.

4. I return to frame 0, click on the lowest bone, and right click => new constraint => dynamic constraint

5. I still have an animation of a stiff three-bone stick moving back and forth. No swinging.

 

Stiffness is set to 50% by default. If I try to change this value, it jumps back to 50% automatically. In fact, all of the dynamic options properties jump back to their defaults if I try to change them. Why is everything frozen? When am I supposed to see the effects of the contraint? What am I doing wrong?

Check to make sure that "Simulate on the fly" is set to "on" in the dynamic constraint. Then, instead of playing your animation, quickly scrub through it back and forth...that should increase the effect.

 

Hope that helps.

I think there is a bug with this version. I've been trying to setup some dynamics and I'm having the same problem. I'll look into it more and send in a report. You should send in a report as well.

The above test worked fine for me in v13.0o on a PC...did you set the constraint to 'spring'? I HAVE been having issues with this latest version and dynamic-constraints that were set-up in previous v13's.

You should feel lucky then Matt, I tried setup it up again and it still doesn't work. I can't even change it to spring.

I reported this on AM:Reports a few weeks ago. It has been confirmed (13o), assigned, worked on, and fixed (by Bob). Yippie! We just need to wait for verions 13p to come out.

Cool.
