X-Pose Picker is a character animation and rigging tool that allows users to create custom, two-dimensional selection interfaces. It enables animators to select bones, rig controls, and objects using a dedicated visual layout instead of clicking directly within a crowded 3D viewport. The system is designed to work with any rig structure, including standard solutions like Rigify, Auto-Rig Pro, Blenrig5, and Mixamo.

The tool features a customizable workspace where users can organize controls across multiple tabs, import SVG shapes for custom buttons, and execute Python scripts directly from the interface. Projects are saved in a dedicated file format that supports namespace logic, making it possible to manage multiple characters within complex scenes. Additional layout tools include z-order arrangement, alignment functions, and an x-mirror feature for symmetrical control creation.
