Overview

Animate objects, cameras, lights, and properties in Blender — keyframes, F-curves, easing (Bezier, Linear, Sine, Bounce, Elastic), shape keys (morph targets / blendshapes / visemes), drivers (Python expressions on properties), NLA actions for reuse and layering. Use whenever the user asks to "animate this", "make it move / rotate / scale over time", "add keyframes", "loop / oscillate", "shape key / morph / blendshape", "visemes for lip sync", or any time-based property change. Make sure to use this skill even if the user does not say "animate" — also covers "spin it slowly", "make it wave", "fade in / out", "pulse", "facial expression".

Blender Animation

Animate properties over time. Most animation is just keyframes — the trick is choosing the right interpolation and easing for the motion's character.

Recipes

Recipe 1 — Animate object position (Bezier, natural)

import bpy

obj = bpy.data.objects['GEO-target']

scene = bpy.context.scene
scene.frame_start = 1
scene.frame_end = 60
scene.render.fps = 24

# Keyframe 1: at frame 1, at origin
scene.frame_set(1)
obj.location = (0, 0, 0)
obj.keyframe_insert('location', frame=1)

# Keyframe 2: at frame 60, moved to (5, 0, 0)
scene.frame_set(60)
obj.location = (5, 0, 0)
obj.keyframe_insert('location', frame=60)

print(f"animated:{obj.name} 1->60")

Default interpolation = Bezier (smooth in/out). To make it linear, see Recipe 3.

Recipe 2 — Animate rotation (a 360° spin)

import bpy, math

obj = bpy.data.objects['GEO-target']
scene = bpy.context.scene

# Use rotation_euler with a single axis.
# WARNING: animating past 180° on Euler can flip; use multiple keyframes or quaternions for full rotations.

scene.frame_set(1)
obj.rotation_euler = (0, 0, 0)
obj.keyframe_insert('rotation_euler', frame=1)

scene.frame_set(120)
obj.rotation_euler = (0, 0, math.radians(180))   # half-turn
obj.keyframe_insert('rotation_euler', frame=120)

scene.frame_set(240)
obj.rotation_euler = (0, 0, math.radians(360))   # full turn
obj.keyframe_insert('rotation_euler', frame=240)

print(f"rotated:{obj.name} 360 over 240 frames")

For perfectly constant spin, set keyframes to Linear interpolation (Recipe 3).

Recipe 3 — Set keyframes to Linear interpolation

⚠ Blender 5.x changed the Action API. Legacy action.fcurves was removed in favour of layered Actions: action.layers[].strips[].channelbags[].fcurves. Use this compat helper.

import bpy

def get_fcurves_compat(action):
    """Return all fcurves on an Action — works on both legacy (≤4.x) and layered (5.x+) actions."""
    if hasattr(action, 'fcurves'):
        return list(action.fcurves)
    fcurves = []
    for layer in action.layers:
        for strip in layer.strips:
            if hasattr(strip, 'channelbags'):
                for cb in strip.channelbags:
                    fcurves.extend(cb.fcurves)
    return fcurves

obj = bpy.data.objects['GEO-target']
if obj.animation_data and obj.animation_data.action:
    for fc in get_fcurves_compat(obj.animation_data.action):
        for kp in fc.keyframe_points:
            kp.interpolation = 'LINEAR'
print(f"interp:linear {obj.name}")

Other options: 'BEZIER' (default), 'CONSTANT' (step), 'SINE', 'QUAD', 'CUBIC', 'QUART', 'QUINT', 'BOUNCE', 'ELASTIC', 'BACK'.

Recipe 4 — Bouncy / cartoon easing on a specific keyframe

import bpy

# (Re-use get_fcurves_compat from Recipe 3.)
def get_fcurves_compat(action):
    if hasattr(action, 'fcurves'):
        return list(action.fcurves)
    fcurves = []
    for layer in action.layers:
        for strip in layer.strips:
            if hasattr(strip, 'channelbags'):
                for cb in strip.channelbags:
                    fcurves.extend(cb.fcurves)
    return fcurves

obj = bpy.data.objects['GEO-target']
target_fc = None
for fc in get_fcurves_compat(obj.animation_data.action):
    if fc.data_path == 'location' and fc.array_index == 2:   # Z axis
        target_fc = fc
        break

if target_fc and len(target_fc.keyframe_points) >= 2:
    last_kp = target_fc.keyframe_points[-1]
    last_kp.interpolation = 'BOUNCE'
    last_kp.easing = 'EASE_OUT'    # 'AUTO', 'EASE_IN', 'EASE_OUT', 'EASE_IN_OUT'
print('animated:bouncy_landing')

Recipe 5 — Shape keys (morph / blendshape / viseme)

import bpy

mesh_obj = bpy.data.objects['GEO-character_face']

# Add basis (the rest pose)
if mesh_obj.data.shape_keys is None:
    basis = mesh_obj.shape_key_add(name='Basis')

# Add a morph target
smile = mesh_obj.shape_key_add(name='Smile')
smile.value = 0.0
# ⚠ At this point, switch to Edit Mode interactively and modify the mesh while 'Smile' is selected.
#   Or set vertex coordinates programmatically (advanced).

# Animate
scene = bpy.context.scene
scene.frame_set(1)
smile.value = 0.0
smile.keyframe_insert('value', frame=1)

scene.frame_set(24)
smile.value = 1.0
smile.keyframe_insert('value', frame=24)

print('animated:shape_key_smile')

For lip sync: standard 15-viseme set (Oculus / ARKit) — name shape keys viseme_aa, viseme_E, viseme_O, etc. Animate each viseme's value across the audio timeline.

Recipe 6 — Driver (one property as expression of another)

import bpy

# Example: child object's X = parent's X × 2
target = bpy.data.objects['GEO-follower']
source = bpy.data.objects['GEO-leader']

fc = target.driver_add('location', 0)   # X axis
driver = fc.driver
driver.type = 'SCRIPTED'

# Add variable referencing source's X position
var = driver.variables.new()
var.name = 'src_x'
var.type = 'TRANSFORMS'
var.targets[0].id = source
var.targets[0].transform_type = 'LOC_X'
var.targets[0].transform_space = 'WORLD_SPACE'

driver.expression = 'src_x * 2'
print(f"driver:{target.name}.x = {source.name}.x * 2")

Recipe 7 — Push current animation to NLA strip (for reuse)

import bpy

obj = bpy.data.objects['GEO-character']

if obj.animation_data and obj.animation_data.action:
    track = obj.animation_data.nla_tracks.new()
    track.name = 'NLA-Walk'
    strip = track.strips.new('Walk', start=1, action=obj.animation_data.action)
    obj.animation_data.action = None    # clear timeline; NLA owns the animation
    print(f"nla:pushed_walk_strip")

After this, the animation is reusable — duplicate the strip, scale time, blend with other tracks.

Recipe 8 — Subtle idle animation (loopable rotation)

import bpy, math

obj = bpy.data.objects['GEO-target']

# Tiny sway around Y, 4-second loop
scene = bpy.context.scene
scene.frame_start = 1
scene.frame_end = 96    # 4s at 24fps

scene.frame_set(1)
obj.rotation_euler = (0, math.radians(-2), 0)
obj.keyframe_insert('rotation_euler', frame=1)

scene.frame_set(48)
obj.rotation_euler = (0, math.radians(2), 0)
obj.keyframe_insert('rotation_euler', frame=48)

scene.frame_set(96)
obj.rotation_euler = (0, math.radians(-2), 0)
obj.keyframe_insert('rotation_euler', frame=96)

# Set extrapolation mode to cycle (loop)
def get_fcurves_compat(action):
    if hasattr(action, 'fcurves'):
        return list(action.fcurves)
    fcurves = []
    for layer in action.layers:
        for strip in layer.strips:
            if hasattr(strip, 'channelbags'):
                for cb in strip.channelbags:
                    fcurves.extend(cb.fcurves)
    return fcurves

if obj.animation_data and obj.animation_data.action:
    for fc in get_fcurves_compat(obj.animation_data.action):
        fc.modifiers.new('CYCLES')
print('animated:idle_loop')

Pro animation principles

Slow in, slow out — Bezier handles do this automatically; matches real-world physics
Anticipation — small reverse motion before the main action (jump prep)
Follow-through — secondary parts continue after main motion stops (cape, hair)
Squash & stretch — exaggeration with shape keys or scale animation
Arcs — natural motion follows curves, not straight lines

Common pitfalls

Symptom	Fix
Robotic motion	Default Bezier is correct; Linear is wrong for organic things
Rotation flips at 180°	Use multiple keyframes (90, 180, 270, 360) or quaternions
Shape key changes lost	Must exit Edit Mode to commit shape key state
Animation only on one axis	`keyframe_insert('location', index=0)` for X only; index=1 Y, =2 Z
Driver doesn't update	Refresh viewport; check Preferences → Editing → Allow Driver Python Expression
Render fps mismatch	Set `scene.render.fps` BEFORE animating to avoid timing drift

When to load `references/overview.md`

Load when:

Animation curves need fine tuning (handle types, bezier shape control)
NLA layering / blending needed
Drivers with complex expressions (multi-variable, conditional)
ARKit 52-blendshape full face animation
Walk-cycle / run-cycle / attack patterns

The reference covers: full F-curve interpolation/easing matrix, NLA workflow, drivers cookbook, shape-key best practices, animation principles.

```python
import bpy

obj = bpy.data.objects['GEO-target']

scene = bpy.context.scene
scene.frame_start = 1
scene.frame_end = 60
scene.render.fps = 24

# Keyframe 1: at frame 1, at origin
scene.frame_set(1)
obj.location = (0, 0, 0)
obj.keyframe_insert('location', frame=1)

# Keyframe 2: at frame 60, moved to (5, 0, 0)
scene.frame_set(60)
obj.location = (5, 0, 0)
obj.keyframe_insert('location', frame=60)

print(f"animated:{obj.name} 1->60")
```

Default interpolation = Bezier (smooth in/out). To make it linear, see Recipe 3.

### Recipe 2 — Animate rotation (a 360° spin)

# Use rotation_euler with a single axis.
# WARNING: animating past 180° on Euler can flip; use multiple keyframes or quaternions for full rotations.

scene.frame_set(1)
obj.rotation_euler = (0, 0, 0)
obj.keyframe_insert('rotation_euler', frame=1)

scene.frame_set(120)
obj.rotation_euler = (0, 0, math.radians(180))   # half-turn
obj.keyframe_insert('rotation_euler', frame=120)

```

For perfectly constant spin, set keyframes to Linear interpolation (Recipe 3).

Install the "blender-animation" agent skill from https://github.com/CheshireJCat/blender/tree/main/skills/create-3d-model/references/modules/blender-animation. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Animate objects, cameras, lights, and properties in Blender — keyframes, F-curves, easing (Bezier, Linear, Sine, Bounce, Elastic), shape keys (morph targets / blendshapes / visemes), drivers (Python expressions on properties), NLA actions for reuse and layering. Use whenever the user asks to "animate this", "make it move / rotate / scale over time", "add keyframes", "loop / oscillate", "shape key / morph / blendshape", "visemes for lip sync", or any time-based property change. Make sure to use this skill even if the user does not say "animate" — also covers "spin it slowly", "make it wave", "fade in / out", "pulse", "facial expression". After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"cheshirejcat-blender-animation","task":"Install blender-animation","agent":"codex","outcome":"success","install_used":true}.

Overview

Blender Animation

Decision tree

Recipes

Recipe 1 — Animate object position (Bezier, natural)

Recipe 2 — Animate rotation (a 360° spin)

Recipe 3 — Set keyframes to Linear interpolation

Recipe 4 — Bouncy / cartoon easing on a specific keyframe

Recipe 5 — Shape keys (morph / blendshape / viseme)

Recipe 6 — Driver (one property as expression of another)

Recipe 7 — Push current animation to NLA strip (for reuse)

Recipe 8 — Subtle idle animation (loopable rotation)
