Installation

1. In Blender, open Edit > Preferences > Add-ons.
2. Click the arrow next to Install and choose Install from Disk.
3. Select the downloaded .zip file and confirm.
4. Enable the addon by ticking its checkbox.
5. Open the 3D Viewport sidebar (N key) and go to the Instant-Life tab.

Quick start

1. Select your character: the armature or its mesh.
2. In the Instant-Life panel, choose a Preset.
3. The bones are found automatically on most humanoid rigs. If one is missing, assign it in the Bone Setup tab.
4. Press Generate to apply idle motion.
5. Play the timeline. The character moves continuously without any keyframes.
6. Adjust Amplitude and Speed while it plays. With Live Update on, changes apply at once.
7. Press Remove at any time to strip all idle motion.

Panels

• Main: character, preset, body part toggles, amplitude, speed, seed, Live Update, Match FPS, generate and remove, fade in and fade out.
• Bone Setup: automatic detection for Rigify, CloudRig, Auto-Rig Pro, Mixamo, Unreal, Daz, Character Creator, VRM and most other humanoid rigs, fourteen bone fields, validate, save and load setups.
• Custom Bone Setup: add your own body parts such as tails, wings or ears, mirror bones, and save characters to reuse or share.
• Preset Creator: design, save, export and import your own motion presets.
• Face Animation: eye blinks from recorded open and closed poses, eye darts from recorded gaze poses, and head follow.
• NLA Bake: bake the modifier motion to keyframes in an NLA strip for game engine export, with an optional seamless loop.

Tips

• Select several characters and click Generate once; each gets its own variation.
• The motion is additive, so it layers on top of keyframed and mocap animation.
• Always bake to an NLA strip before exporting to a game engine, since most engines do not evaluate F-Curve modifiers.
• Use Validate in the Bone Setup tab to catch typos or renamed bones before generating.
