Rigid bodies and Rigged characters

[kevbogsp]

I am trying to create a character with a chain over his shoulder. I would like to make the chain interact with the character (hang on his shoulder, etc.). I created an active rigid body on each of the chain links and on the character's skin (made a rigid body after binding). All collisions seem to work when the character is still. However, when I animate the pose of the character (like move his arm up), the chain does not collide with his arm in the new position. It instead collides with the arm in the bind pose.

Is there a way to make an animated character affect rigid body objects?

Thanks,
Kevin

Dear Kevin
I think you need to rig your character with maya dynamics constrins like hinge and pin and ....
and after that use wrap deformer to run the skin.

or you can use a softeware call endorphin.

You can export data as motion capture data tp maya the software is expensive.
If you could get a good result with maya please let me know.

I don't think you should make the skin rigged. Instead, you create less tesslate polygon, approximate to your skin surface. used that polygon as the passive rigied body, then parent the polygon surface to the bones of the charater.Maya didn't do dynamic simulation on shapes with deformers like lattice, blendshape, maya only do collision on the original shapes withour deformer, so your chains does not collided with arm in the new position,because the bone has changed the shape of the arm.
