2.0 - Major Update

New Features

Simple, More & Advanced Modes

Easy Driver now includes three interface levels:

• Simple - Essential tools only.
• More - Adds custom property sources, shape key sources, and curve types.
• Advanced - Unlocks world space, invert range, and all advanced options like expression editing and fine tuning most values.

Choose the level that fits your workflow.

Curve Types

Control how source values map to targets with:

• Linear
• Bezier
• Ease In
• Ease Out
• Step
• Loop
• Ping-Pong
• Infinite

Multi-Source Blend

Combine multiple sources into a single driver using:

• Add
• Multiply
• Subtract
• Distance

Shape Keys as Sources

Drive any property directly from a shape key value.

Custom Path Sources

Use virtually any property as a driver source, including node inputs, modifiers, constraints, scene properties, and more. Uses the Path listener just like custom paths for targets

World Space Support

Read object and bone transforms in either Local or World space.

Record Objects or Bones in target or source!

Record Min/Max values from either Object Mode or Pose Mode. Easy Driver automatically detects the correct mode.

Edit Recorded Values

Adjust recorded Min/Max values manually without re-recording the pose.

Custom Property Browser

Browse all custom properties on the selected object or bone and select them with a click. Add them easily as well!

Driver Review Panel

View every Easy Driver-created driver in one place. Inspect, edit expressions, remove individual drivers, or clean up broken ones with a single click.

(Only compatible with Easy Driver 2.0+ created drivers for now)

Invert Range (Advanced)

Swap recorded Min and Max values with a single checkbox.

Bug Fixes

• Fixed incorrect source detection for some custom property and node paths.
• Renamed Remove Target to better reflect that it removes both objects and bones.
• Improved setup and missing-reference error messages.

Changelog

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 – 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 0–1.
• Fixed object fine-tune max value storing as a tuple.

• Fixed quaternion bone flicker while recording poses.
• Fixed mirrored pose targets breaking after multi-rig update.
• Removed duplicate import statements.
• Fixed improper bpy.types.Scene property registration causing Blender 4.2+ extension issues.

Changelog

Custom Paths bugfix

• Fixed an issue where you could not change the min/max values of boolean properties (default 0-1). Now you can put in any number for min/max

Changelog

Blender 5.0 bugfix

• Fixed pose recording bug in blender 5.0

Plugin is compatible and tested from blender 3.2 up to 5.0 - report any issues on GitHub~

Changelog

Blender 5.0 bugfix

• Fixed recording error in blender 5.0 AttributeError: 'Bone' object has no attribute 'select'

Plugin is now compatible and tested from blender 3.2 up to 5.0 - report any issues on GitHub

Changelog

Bug fix

• Custom path eyedropper is now less susceptible to outside plugin interference by verifying the path is valid before adding to the path input field.

Changelog

Icon display issue in Blender 4.4

• Fixed incompatible icon issues that caused the addon to not display anything in 4.4

Changelog

Custom paths QOL and bug fixes

• Fixed eyedropper to ignore some internal updated paths
• Added record min and record max buttons for getting values of custom properties and positions easily
  • Great for if you want to drive object positions!

Changelog

Bug fix

• Fixed a rare bug that effects render settings when using the custom paths eyedropper

Compatibility

• Now completely compatible all the way down to blender 3.0.0 up to 4.5.0+

Changelog

Features & Improvements

• Enhanced Mirror System: Significantly expanded bone naming convention support for better automatic mirroring
• Scale Constraints: Added scale constraint support to the constraints creation system
• Expanded Custom Path Support: Added comprehensive support for:
  • Camera settings and properties
  • Extended material properties and nodes
  • Light settings, types, and values
  • Rigid body physics properties
  • And many more object properties
• You can now record rotations of bones in an IK chain
  • no need to turn off IK anymore!
• You no longer need to have the object selected when recording max for source
• Added some improvements to recording poses
  • Better error handeling
  • If a bone exists, you can easily update its max
• Creating constraints now toggles "affect transforms"

Bug Fixes

• Fixed custom path issues affecting certain material properties
• Resolved fine-tune UI not updating properly for scale transformations

UI changes

• Streamlined Interface: Removed redundant information and unnecessary UI elements for a cleaner, more focused experience
• More Compact Layout: Significantly reduced UI bloat while maintaining full functionality
• Dynamic Source Selection: Users can now change source objects on-the-fly while preserving all recorded values
• Simplified Workflow: Removed the Validate button from custom paths (no longer required)

Changelog

Driver source - scale

• You can now use scale as a driver source
• If all 3 axises are scaled, it will use the Z axis by default!

Changelog

Bug fixes

• Remove driver button removes all drivers on a rig - Fixed by only removing drivers from configured source and targets
• Removed buffer values from driver creation
• Removed tolerance for constraints - now sets constraints with exact values

Changelog

bug fix

• Fixed an issue with creating constraints via the "lock recorded" and "lock to one axis" buttons

Changelog

New Feature!

MIRROR

• Source mirroring - Mirror your source bone/object to the opposite side
  • Preserves all recorded transformations - Keep your min/max values the same!
  • Smart bone detection - Automatically finds the mirrored bone in your armature
• Target mirroring - Mirror ALL targets at once
  • Works with custom bone poses and shape keys
  • Only mirrors each entry with a valid mirror, skips all entries that do not have an existing opposite
• Detects multiple types of naming conventions
  • L_arm, LeftArm, left-arm, l.arm, arm.l, ARM.Left, arm_L, armLeft, etc

Changelog

Hotfix

• previous update broke path parsing, this update should fix these issues!
