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

code

1. create_animation: name="walk", animation_length=1.0, loop=true
2. 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)

code

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

code

animation_graph_editor: bone_name="arm", channel="rotation", action="smooth"

Copy Animation to Mirrored Bone

code

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

code

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

Bone Rigging

Create Bone Structure

code

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

code

bone_rigging: action="set_pivot", bone_data={name: "arm_left", origin: [4, 22, 0]}

Timeline Control

code

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