Shapekey Driver Builder provides a simplified interface for connecting shapekeys to armature bones using drivers. It allows you to configure facial rigs, corrective shapekeys, and muscle flex deformations by recording bone positions to trigger specific shapekey values. The tool includes a driver flipping feature that mirrors setups to the opposite side of a rig with a single click, provided bones and shapekeys follow standard naming conventions. Because it functions strictly as a setup tool, it generates native Blender drivers. The resulting blend file can be shared and used by others who do not have the addon installed.
