Dynamics question

[jason1025]

Hi Folks

 

I am having trouble Limiting the rotation for a bone with a Dynamic constraint.

 

Basically I want I have a hinge that should only move on one axis. I have limited the bone to that axis via the manipulator options. Now I want to make that bone dynamic so that it swings up and down along that axis as the rest of the model moves. Unfortunately the Dynamics constraint does not seem to adhere to the limit manipulator option.

 

 

Any Ideas?

Is this something I should request as a feature in AM?

Is this something I am doing wrong?

 

The video illustrates my problem.

The manipulator options in the Model's Properties are for limiting how the bone can be manipulated by you in a chor or action. It doesn't limit how the bone moves via other means.

 

To limit the bone so it will only rotate along a certain axis, no matter what, place a Euler Constraint on it.

Will that constraint allow the dynamics constraint to continue to work the way I want?

 

How do you perform a euler constraint?

Figured it out. thanks for pointing me in the right direction.

 

I wen into my relationship for that bone.

in addition to the dynamic constraint I right clicked and added the euler constraint.

In the euler properties I zero out the y and z axis.

It worked perfectly.

 

Its amazing how much control you can have with the dynamic constraints

Here is a video of the fix

 

Hope it helps
