Bone wiggle drive vertical bone (or points) position?

Post by madrobot »

I'm doing a test using bone wiggle to drive the mouth.
But of course it gives you rotation. And I can't constrain
a bone to have its position driven by another bone's
rotation (can I?)

So the movement is along an arc.
Any ideas how I could get that along a path,
up and down?

Bind the point that needs to travel up and down to two bones (50% to each) that rotates in different directions but aligned properly. Both would pull/push from/to the bone to the same direction when rotate. Obviously it has a limit. You cannot push/pull the point upper/lower than the distance to each rotation center of each bone (that has to be the same for both).

If you don't get it by your self, ask again.

Genete! I'm shocked!

Your "spring" bones do this quite nicely...

Yeah, when I saw the topic title, I immediately thought of Genete's springy rig. Genete's finally done so much he's forgetting some of it. :lol:

The cool thing about this is that if you have clean dialog without music or sound effects is that it works really well. I used a piece of dialog I had from another project that was done in a studio and had no other sound but the voice. The bone wiggle really did a good job matching up with the sound.

I used a lower rotation limit on the upper lip bone. I had to use a huge value on the lower lip bone to get any noticeable motion. It must be based on the max volume of the sound.
