Biped Helper + Picker is a support interface for 3ds Max that runs in conjunction with the main Biped panel. It provides quick access to existing Biped panel tools while adding functionality the Biped panel doesn't support, all through a single companion interface. An online guide is available through the developer's links.
The toolset covers limited parts selection with IK limb pivot settings, keying operations, TCB settings, and time range settings for range-based operations. Reference options include ghosting, pose buffering, geometry snapshots, and placed trajectory helpers. You can load and save animation clips, manage layers, retarget IK constraints, copy and paste poses or postures, mirror limbs, and align fingers and spine. Limb space settings support Body and Object modes.
Version 3.5 added Apply Transform and Foot Cleanup functionality to a dedicated Picker UI first introduced in 3.4. The Picker mirrors most of the main interface and is designed to work with a standard human Biped configuration. It's compatible with 3ds Max 2020 through 2025.
