View Full Version : Scaling a joint without moving others in chain
02-01-2008, 12:36 AM
I'm wondering if anyone has 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 translation of the joint below it in the chain. Thanks for your help.

You can visually make one bigger by chaging his radius in attribute editor.

I need to scale the joint so that it changes the shape of geometry that is bound to it.

uncheck the "segmentScaleCompensate" under "joint" for every joint in atrrEditor .
or select every jnt in chain then run scripts below:
string $sel = `ls -sl`;
for ($singleJnt in $sel)
setAttr ($singleJnt + ".segmentScaleCompensate") 0;
hope this helps

As long as the lower joints are parented to the one you are scaling, they will be moving. You must search for other possibilities , for example, can you bind to another joints on top of these?

I'm not sure if I undertsand it correctly, but as I read you want to scale a joint, but not affect it's length? So can't you just scale the y and z axis of the joint if z is pointing down the chain?

Well unfortunately the engine I'm working with only allows uniform scale but I think I found a solution. I'm just going to creat a locator which I'll parent constrain to the first joint then parent constrain the child joint to the locator. That way the joint will stay put and I can scale the parent joint without effecting the childs location relative to the parent. For some reason I think I was trying to make it more complicated than it needed to be at first but this solution is working so far. Thanks for all of the replies.
