What is it?

BlenderBiped is a Rigify feature set that adds Biped-style rig editing and animation tools to Blender. It is installed as an add-on package on top of Rigify, which must already be installed and enabled in Blender.

The current release, 0.8.9, changes how sliding upper-arm rotation works: the hand IK target stays in place while the elbow direction changes. This extends the sliding thigh rotation added in 0.8.8, and existing rigs do not need to be regenerated.

Installation uses either a Blender installer ZIP, which provides an upgrade action in its preferences, or a feature-set ZIP installed through Rigify's Install Feature Set from File option. The project targets Blender 5.2 or later. Documentation is included in Korean, English, Japanese, and Simplified Chinese.

  • Requires Rigify installed separately, since the full Rigify add-on is not bundled.
