AI-generated overview

Guides creation and management of 3D model animations in Blockbench through MCP tools.

What it does: This skill provides instructions for animating 3D models in Blockbench using MCP tools. It documents tools for creating animations, managing keyframes, editing curves, rigging bones, controlling the timeline, and batch or copy-paste operations. It includes example workflows such as walk cycles, smooth curves, mirrored animation, and timing adjustments.
When to use it: Use it when animating 3D models in Blockbench, such as building walk cycles, idle or combat animations, or complex multi-bone motion. It also fits tasks involving keyframes, bone rigs, animation curves, or timeline settings.
Requirements: Requires Blockbench with the referenced MCP tools available; no scripts are shipped, only instructions.

Blockbench Animation

Create animations for 3D models using Blockbench MCP tools.

Available Tools

Tool	Purpose
`create_animation`	Create animation with keyframes for bones
`manage_keyframes`	Create/edit/delete keyframes per bone and channel
`animation_graph_editor`	Fine-tune animation curves (smooth, linear, ease)
`bone_rigging`	Create/modify bone structure for animation
`animation_timeline`	Control playback, time, FPS, loop settings
`batch_keyframe_operations`	Batch operations: offset, scale, reverse, mirror
`animation_copy_paste`	Copy animation data between bones/animations

Quick Start

Create a Simple Animation

1. create_animation: name="walk", animation_length=1.0, loop=true2. manage_keyframes: bone_name="leg_left", channel="rotation",   keyframes=[{time: 0, values: [30, 0, 0]}, {time: 0.5, values: [-30, 0, 0]}]3. animation_timeline: action="play"

1. create_animation: name="walk", animation_length=1.0, loop=true2. manage_keyframes: bone_name="leg_left", channel="rotation",   keyframes=[{time: 0, values: [30, 0, 0]}, {time: 0.5, values: [-30, 0, 0]}]3. animation_timeline: action="play"

Animation Channels

position - [x, y, z] offset
rotation - [x, y, z] degrees
scale - [x, y, z] or uniform number

Interpolation Types

linear - Constant rate
catmullrom - Smooth spline
bezier - Custom curves
step - Instant change

Common Workflows

Walk Cycle (1 second)

create_animation: name="walk", animation_length=1.0, loop=true, bones={  "leg_left": [    {time: 0, rotation: [30, 0, 0]},    {time: 0.5, rotation: [-30, 0, 0]},    {time: 1.0, rotation: [30, 0, 0]}  ],  "leg_right": [    {time: 0, rotation: [-30, 0, 0]},    {time: 0.5, rotation: [30, 0, 0]},    {time: 1.0, rotation: [-30, 0, 0]}  ]}

create_animation: name="walk", animation_length=1.0, loop=true, bones={  "leg_left": [    {time: 0, rotation: [30, 0, 0]},    {time: 0.5, rotation: [-30, 0, 0]},    {time: 1.0, rotation: [30, 0, 0]}  ],  "leg_right": [    {time: 0, rotation: [-30, 0, 0]},    {time: 0.5, rotation: [30, 0, 0]},    {time: 1.0, rotation: [-30, 0, 0]}  ]}

Smooth Curves

Copy Animation to Mirrored Bone

animation_copy_paste: action="copy", source={bone: "arm_left"}animation_copy_paste: action="mirror_paste", target={bone: "arm_right", mirror_axis: "x"}

animation_copy_paste: action="copy", source={bone: "arm_left"}animation_copy_paste: action="mirror_paste", target={bone: "arm_right", mirror_axis: "x"}

Batch Timing Adjustment

batch_keyframe_operations: operation="scale", selection="all",  parameters={scale_factor: 2.0}  # Double animation duration

batch_keyframe_operations: operation="scale", selection="all",  parameters={scale_factor: 2.0}  # Double animation duration

Bone Rigging

Create Bone Structure

bone_rigging: action="create", bone_data={name: "spine", origin: [0, 12, 0]}bone_rigging: action="create", bone_data={name: "head", origin: [0, 24, 0], parent: "spine"}

bone_rigging: action="create", bone_data={name: "spine", origin: [0, 12, 0]}bone_rigging: action="create", bone_data={name: "head", origin: [0, 24, 0], parent: "spine"}

Set Pivot Point

Timeline Control

animation_timeline: action="set_fps", fps=60animation_timeline: action="set_length", length=2.5animation_timeline: action="loop", loop_mode="loop"  # or "once", "hold"animation_timeline: action="set_time", time=0.5animation_timeline: action="play"

animation_timeline: action="set_fps", fps=60animation_timeline: action="set_length", length=2.5animation_timeline: action="loop", loop_mode="loop"  # or "once", "hold"animation_timeline: action="set_time", time=0.5animation_timeline: action="play"

Tips

Use list_outline to see available bones before animating
Set up bone hierarchy first with bone_rigging before adding keyframes
Use catmullrom interpolation for organic movement
Use step interpolation for mechanical/robotic movement
Mirror animations for symmetrical rigs to save time
