smp Child bone not inheriting parent bone's transform?

[dl2002081]

Hi,

I am currently trying to attach a child bone under a parent bone that is affected by smp collision.

The body / skeleton I am using in baseline is the GT-softbody ones, located here: https://www.nexusmods.com/skyrimspecialedition/mods/152103

I created (copied from elsewhere) a set of bones and attached it under the parent bone in nifskope.

The Soft_LN00 is already in the skeleton, and the left nipple is weighted based on that.

 

However, the new child bone (breast.LM00.01) is not following the parent (Soft_LN00)'s movement. when the parent bone is moved due to collision, the child bone just stays at the original location and is not following the movement of its parent bone.

 

Is there anything extra that needs to be done to parent on a SMP bone? Any help is appreciated.
