Master Shape Keys v3.9.1

Master Shape Keys is an addon for Blender that gives you advanced control over shape key organization and management. The tool lets you separate individual shape keys into multiple independent keys, or merge and group them together—whichever approach suits your workflow. This is especially useful for character animation, where you might want to isolate controls for asymmetrical features like lips, eyebrows, and cheekbones to achieve more nuanced facial expressions and better manage your shape key hierarchy.
