I'd like to know if there's any way to preserve bone constraints from the metarig into the generated rig. I could imagine multiple uses for this (basically any unconventional type of limb or body part), but my current use is that I want to replicate the popular 2B character model's breast bones in my own characters while using a Rigify armature. Rigify's default of a single bone just doesn't deform right and I'm a stickler for details.
This setup requires a few 2-bone chains with IK constraints that target the central breast bone, and I can't seem to copy the IK constraints automatically. Considering I'd like to reuse this setup for multiple characters, doing it manually after generating each rig is out of the question.
Thanks in advance!
