Rigging

The Rigging section lives in src/mpfb/ui/rigging/. Its root panel is MPFB_PT_Rig_Panel, which appears as "Rigging" under the Model category in Blender's sidebar. The panel is visible when the active object is a character's basemesh, body proxy, or any skeleton. Like the New Human section, the root panel acts as a container — all actual controls are in the child panels nested inside it.

Sub-sections

Sub-section directory	Panel label	Default state	Description
standardrig/	"Standard rig"	Expanded	Add a built-in (non-rigify) standard rig; on an existing standard rig, manage IK/FK rig helpers for arms, legs, fingers, and eyes
rigifyrig/	"Rigify rig"	Expanded	Recommended rigify workflow: add a rigify meta rig, then generate the final rigify rig
customrig/	"Custom rig"	Collapsed	Attach a custom rig built with MakeRig or imported from a third-party source
applypose/	"Load pose"	Collapsed	Apply a saved pose or partial pose to the active armature, or import a pose from a BVH file
addcycle/	"Add walk cycle"	Collapsed	Deprecated — walk cycle panel, superseded by the Mixamo workflow; collapsed because it only contains a deprecation notice
