Hello, I am trying to apply gravity to a ponytail bone structure. The bones are in the same layer as the rest of the object and are parented to the head. Is there a way to use IKboost with only these specific bones or do I need to use it on the whole object. I am stuck! Does the ponytail mesh and/or bones need to be on a separate layer to do this? If so…I was having trouble with the bones following the head movement. Thanks for any input!

I’m glad you are pursuing secondary animation, it’s sometimes overlooked.
I don’t know all about IKBoost, but yes, IKBoost is applied to all bones. There are ways to lock the bones and use FK on them. That said, I’ll explain another, more manual way.
. Create your IK chain for the ponytail. (set the parent-most bone to ‘unaffected ik of dependents’, set goal for last-child bone, set IK controllers for the bones, etc…)
. Align your bones so Heading and Pitch are aligned for the entire chain.
. Now, choose ONE axis (heading or pitch) and assign a higher Stiffness to the IK controller under the (m) motion modifier panel. I usually assign ‘10’ to heading so I can get a more responsive Pitch.
Now, with that Goal object, you can also give it a motion modifier plugin such as ‘springthing’ or a delay so you don’t have to manually animate all the time.
