Scaling Joint Without Moving It's Child

[monkeytongue]

Does anyone have a solution to this problem I'm having? I need to be able to apply a uniform scale to one joint while not effecting the position of joints below it in the chain.

Thanks for the help.

I would do this as a separate deformer, maybe even a blend shape connected to your joint as a set driven key or something. Whatever you do to the top joint will always follow to the joints below. That's how they work!

You could try setting up a scale negation transform between the scaling joint and the children whose position you want to maintain.
To do this, create a new transform or joint (i'll refer to this as 'scaleNegXform') with the same position and orientation as the joint that will be scaling (i'll call this 'originalXform'), the pivot position of thes two objects must be identical for this to work correctly. To set up the scale negation, you need to have 'scaleNegXform.scale' always equal to 1.0/'originalXform.scale'. You can set this up using a node network or an expressions, I always prefer to use nodes over expressions.
Now, place all the objects that you want to maintain positions of under the 'scaleNegXform' node.
Hope that helps.
