Easy Driver
Easy Driver - Technical Rigging Made Simple As Heck!
đ¤ What does this even do?
Easy Driver is a powerful Blender addon that eliminates the complexity of creating drivers manually.
Perfect for:
- Rigging characters with shape key corrections and flexing
- Creating mechanical animations
- Building interactive controls
- Blender
3.2.0up to5.1.0!!
This addon automatically detects movement patterns and creates perfectly mapped drivers in seconds.
⨠Key Features
đŻ Auto-Detection
- Automatic Axis Detection â Move your bone or object between two positions, and Easy Driver automatically detects which axis changed the most.
- Min/Max Value Recording â Captures exact transformation ranges for perfect mapping.
đ Dual Source Support (what's driving)
- Bone Transforms â Use armature bones as driver sources: scale, rotation, or position.
- IK chain â Can still work even if the bone is controlled by IK or other constraints!
- Object Transforms â Use any object's location/rotation as input.
đď¸ Multiple Target Types (what you're driving)
đš Custom Pose Targets
- Record min/max poses for multiple bones simultaneously.
- Automatically detects which bones changed and on which axes.
- Perfect for facial rigs, mechanical parts, and complex deformations.
đĄ Example: custom poses via bone transformations (toe spread or corrective movement via a bone slider).
đš Shape Key Targets
- Browse and select shape keys from any mesh object.
- Set custom min/max values (0.0 to 1.0) with live feedback so you know EXACTLY what it looks like.
- Drive multiple shape keys at the same time easily.
đĄ Example: viseme control & corrective shape keys.
đš Custom Path Targets
- Drive ANY Blender property using custom paths.
- Built-in path validation.
- Supports both float ranges and boolean toggles.
- Multiple paths can be setup at once.
đĄ Examples: hide/show IK bones, control modifier strength, toggle visibility, adjust constraint influence.
đ ď¸ Extra Features
- Linear Mapping with Clamping â Smooth, predictable transitions (values stay in your set range).
- Batch Driver Creation â Create multiple drivers simultaneously.
- Easy Driver Removal â Clean up drivers with one click.
- Quaternion â Euler Conversion â Automatically handles rotation mode conflicts.
đ¨ Perfect For
- Character Rigging â Facial controls, finger poses, corrective shapes
- Mechanical Rigs â Pistons, gears, hydraulics, robotic joints
- Architectural Viz â Doors, windows, moving parts
- Motion Graphics â Abstract animations, UI elements
- Product Visualization â Exploded views, configuration options
What's New
1.6.0 May 19th, 2026
New Features
Custom Property Source
- Added a new Custom Prop source mode.
- Create and use custom properties instead of physical objects
- Supports object and bone custom properties.
- Works with Pose, Shape Keys, and Custom Paths.
- Compatible with Blender 4.0 â 5.1.
Multi-Rig Pose Targets
- Record Min/Max across multiple armatures at once.
- Supports same-named bones on different rigs safely.
- UI now groups targets by armature.
- Shows Min/Max recording status per bone.
Bug Fixes
- Fixed drivers not generating correctly for bones on different armatures.
- Fixed shader node socket drivers in Blender 5.0+.
- Shape key min/max values are no longer limited to 0â1.
- Fixed object fine-tune max value storing as a tuple.
- Fixed blank success message when adding shape key targets.
- Fixed quaternion bone flicker while recording poses.
- Fixed mirrored pose targets breaking after multi-rig update.
- Removed duplicate import statements.
- Fixed improper
bpy.types.Sceneproperty registration causing Blender 4.2+ extension issues.
Works for basic transforms but not for custom properties driving shapekeys.

I love this addon. It's so fast and intuitive to create and reiterate shape key drivers. I rigged a cartoony character's entire face in under an hour. Plus the dev is updating it an adding more functionality. I am looking forward to using this for a long time.
