Easy Driver - Technical Rigging Made Simple As Heck!

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, or building interactive controls, this addon automatically detects movement patterns and creates perfectly mapped drivers in seconds. Compatible in Blender 3.0 up to 4.5 and higher! Frequently updated for more features and bug fixes!

Key Features

🎯 Auto-Detection

• Automatic Axis Detection: Move your bone or object between two positions, and Easy Driver automatically detects which axis changed the most
• Min/Max Value Recording: Captures exact transformation ranges for perfect mapping
• Local transformation: Perfect for sources on the move!

🔄 Dual Source Support (what's driving)

• Bone Transforms: Use armature bones as driver sources - scale, rotation, or position
  • IK chain: Can still work even if the bone is controlled by IK!
  • Quaternion Support: Drivers created wont care which rotation mode you have it - Quaternion is auto converted to Euler inside the Driver.
• Object Transforms: Use any object's location/rotation as input

🎛️ Multiple Target Types (what you're driving)

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

Example of custom poses via bone transformations - good for toe spread or corrective movement via a bone slider

Shape Key Targets

• Browse and select shape keys from any mesh object
• Set custom min/max values (0.0 to 1.0 range) - with live feedback so you know EXACTLY what it looks like
• Ideal for facial expressions, corrective shapes, and morphing effects
• Drive multiple shapekeys at the same time easily!

Example of corrective shapekeys and viseme controls

Custom Path Targets

• Drive ANY Blender property using custom paths
• Built-in path validation
• Support for both float ranges and boolean toggles
• Examples: visibility, modifier strength, material properties, constraint influence
• Allows multiple to be setup at the same time

Example of changing a material with an objects position and hide toggle

🛠️ Extra Features

• Linear Mapping with Clamping: Smooth, predictable value transitions - will only go between your set range
• Batch Driver Creation: Create multiple drivers simultaneously
• Easy Driver Removal: Clean up drivers with one click
• Quaternion to Euler Conversion: Automatically handles rotation mode conflicts

🎨 Perfect For

• Character Rigging: Facial controls, finger poses, corrective shapes
• Mechanical Rigs: Pistons, gears, hydraulics, robotic joints
• Architectural Viz: Doors, windows, moving parts
• Motion Graphics: Abstract animations, UI elements
• Product Visualization: Exploded views, configuration options
