ShapeKey Axis Control
ShapeKey Axis Control
ShapeKey Axis Control is a powerful Blender animation and rigging add-on designed to streamline your workflow by mapping shape key values to a 2D Axis Panel (HUD). By manipulating a virtual joystick across the X and Y axes, you can smoothly blend multiple shape keys based on target coordinates. This tool is highly versatile and can be applied to various scenarios, such as facial rigging, eye tracking, lip syncing, and complex mechanical animations. It also features a robust Animation Preset system that allows you to save, recall, and keyframe complex states across multiple objects simultaneously.
Key Features
2D Axis HUD Controller: Control multiple shape keys simultaneously by dragging a target point in a virtual 2D space.
Advanced Blend Modes and Falloffs: Customize the influence area using Box, Radial, or restricted Axis (X-only / Y-only) calculations.
Comprehensive Group Management: Organize your controls into distinct groups (e.g., Eyes, Mouth, Brows) and navigate through them seamlessly.
Global Animation Presets: Capture the joystick positions of all groups across all objects in the scene. Use the "Set" button to record, "Call" to apply, and "Key" to instantly insert keyframes for all affected shape keys on the timeline.
Reset Functions: Quickly clear adjustments using "Reset" for the current group or "Reset All" to zero out the entire model.
What's New
4.0.42 March 3rd, 2026
- Fixed: Shape Keys Not Following Animated Handle — Resolved a critical bug where inserting keyframes for
joy_x/joy_yon the timeline caused the HUD handle to animate correctly but the shape keys themselves did not deform. Root cause was a silent failure in theframe_change_posthandler due to two issues:- Wrong handler signature — Blender 2.8+ passes
(scene, depsgraph)intoframe_change_postcallbacks. The old single-argument(scene)signature caused Blender to silently discard the call, soupdate_shapes()was never invoked during timeline playback/scrubbing. - Missing depsgraph flush — After writing new
sk.valueentries, aview_layer.update()call is now performed to force the dependency graph to propagate the changes and redraw mesh geometry. Without this, values were written in memory but the viewport mesh never reflected them.
- Wrong handler signature — Blender 2.8+ passes
- Fixed: Handler Lost on File Open — Added
@bpy.app.handlers.persistentdecorator toframe_handlerso it survives.blendfile loads. Previously the handler was silently unregistered whenever a new file was opened mid-session.
