Makes bonemerged face cosmetic items like beards, masks, and heads follow the character's face pose. This script runs automatically, you don't need to use another tool or anything!
How it works: this script gets the flexes on all parented models, and matches their values by name. For example, if you use the face poser to set happyBig to 0.75 on a ragdoll, then it'll set happyBig to 0.75 on its attached beard model. Set it back to 0 on the ragdoll, and it'll set it back to 0 on the beard.
(This won't work for HWM character models, unless you can find matching HWM cosmetic models somewhere. Regular cosmetic models don't have the same flexes as HWM models, so they won't be able to match their face pose.)
