About Animation Designer – Unity Editor Tool & Plugin

Unity Animation Editor and Clip Modification Tool

Animation Designer is an editor-based authoring utility that allows developers to modify, restyle, and enhance existing motion clips directly inside the Unity Editor without entering playmode. The system applies procedural motion overlays, inverse kinematics corrections, and bone pose adjustments to existing animation clips, baking the final modified results out into standalone AnimationClip asset files.

Procedural Motion and Pose Adjustments

The tool provides control mechanisms to adjust existing motions without requiring manual keyframe editing on timeline curves:

• Bone and Limb Modifiers: Apply single-bone offset controls alongside procedural limb elasticity to add secondary motion or flappiness to extremities and smaller limbs.
• Inverse Kinematics and Footing: Integrated limbs IK manages hands, legs, and arbitrary bone chains across humanoid, generic, and legacy rigs, while the Legs IK Analyzer inspects and corrects leg or foot stepping artifacts.
• Animation Morphing: Blend individual bone chains from separate clips together, allowing developers to combine in-place attack animations with running or walking motion cycles.
• Custom Procedural Modules: Supports procedural algorithms through modular extensions, including posing modules for humanoid fists, fingers, arms, spines, heads, and legs, alongside the Strafe Creator module to build eight-directional movement cycles from a single locomotion clip.

Editor Workflow and Preset Configuration

Modifications do not inject runtime scripts, custom data components, or overhead onto character GameObjects. Configurations are retained in reusable preset files that store animation adjustment settings for multiple clips. The interface features automatic limb detection for humanoid setups, helper detection for generic and legacy rigs, support for root motion, and a dedicated focus mode that minimizes interface clutter during adjustments.

Use Cases

• Correcting retargeting errors and foot-sliding artifacts on humanoid character locomotion clips.
• Generating eight-directional directional walk and run sets from a single base clip using the Strafe Creator module.
• Overlaying secondary procedural elasticity on appendages, tails, and limbs before baking output into new clips.
• Combining disparate motion clips by blending upper-body combat actions onto lower-body locomotion cycles.
