blockbench-animation_skill

Overview

This skill enables creation and management of animations in Blockbench using MCP tools. It supports building keyframed animations, rigging bones, editing animation curves, and controlling timelines for game-ready 3D model animation. Use it to produce walk cycles, idle poses, combat moves, and complex multi-bone choreography.

How this skill works

The skill exposes task-specific tools: create animations with named timelines and keyframes, manage per-bone keyframes and channels (position, rotation, scale), and edit interpolation curves with a graph editor. It also provides bone rigging utilities, timeline controls (FPS, length, loop), and batch or copy/mirror operations to speed repetitive work. Actions are performed by calling the appropriate tool with parameters like bone name, channel, keyframe list, or operation type.

When to use it

• Creating new animations (walk, idle, attack) for a Blockbench model
• Adding or editing keyframes on specific bones or channels
• Rigging or adjusting bone pivots and parent/child relationships
• Polishing motion with curve editing (smooth, linear, bezier)
• Applying batch timing changes or mirroring animations between sides

Best practices

• Set up a clean bone hierarchy before adding keyframes to avoid mismatched transforms
• Use small animation lengths for cycles (e.g., 1s for walk) and set loop=true for repeating actions
• Prefer catmullrom or bezier for organic motion; use step for robotic, instant changes
• Use copy-and-mirror to duplicate symmetric animations and save time
• Adjust FPS and timeline length early to match target engine playback

Example use cases

• Create a 1-second looping walk cycle using left/right leg keyframes and mirrored timing
• Rig a spine/head chain and animate a breathing idle with subtle rotation and position keyframes
• Polish a sword-swing with the animation_graph_editor to add ease-in and ease-out curves
• Double an animation duration with batch_keyframe_operations scale to reuse a clip at different speeds
• Copy arm animation from left to right using animation_copy_paste then mirror on the X axis
