description: Advise on Reallusion iClone 8 and the Video Mocap plugin (AI body mocap from video) — filming rules, generation settings, mocap cleanup (Motion Correction, Curve Editor), face layering with AccuFACE, FBX export, and integrating the result into ariki-game via tools/cc_retarget.py. Use when the user asks how to do anything in iClone/Character Creator, wants to record video for mocap, or wants an iClone export playing in the game.

# iClone 8 + Video Mocap (advisory + ariki-game integration)
|
|||
|
|
|
|||
|
|
Jeremy uses **iClone 8** (Windows) with the **iClone Video Mocap plugin** — Reallusion's cloud AI body-mocap from ordinary video (QuickMagic-powered, launched Oct 2025, requires iClone 8.63+). This skill answers "how do I do X in iClone" and "how do I get it into the game".

## The 60-second mental model
|
|||
|
|
|
|||
|
|
- iClone animation = **Motion Clip + Layer Keys** (layer keys live inside the clip and can't leave it). Pose edits go through **Edit Motion Layer** (hotkey N, HumanIK IK/FK, pinning). Foot/hand locking via **Reach Target**; foot-slide fix via right-click clip > **Motion Correction** (flatten between iterations). Jitter fix: right-click clip > **Sample Motion Clip to New Layer**, then Curve Editor (F12) **Smooth / Butterworth / Optimize** filters.
|
|||
|
|
- Video Mocap = separate plugin panel: import video → trim to ≤60 s region → **Full Body / Upper Body** (+ Includes Fingers) → cloud generate (5–8 min, costs points) → **Apply Motion** to selected character (check "Apply reference video" for rotoscope cleanup) → clip lands in Content Manager > Motion > VideoMocap as rlMotion. **Body only — no face**; layer AccuFACE/LIVE FACE for talking.
|
|||
|
|
- System: iClone is **60 fps internal, cm units, Z-up**; CC3+ characters bind in **A-pose**; FBX axis conversion comes from the **Target Tool Preset**. Constraint keys (Reach/Link/Look At/Path) need **Animation > Flatten All Motion with Constraint** before export.
|
|||
|
|
|
|||
|
|
## Filming rules that make or break Video Mocap (advise BEFORE recording)
|
|||
|
|
|
|||
|
|
Eye-level static camera, single continuous shot; whole actor in frame the entire time; one person; textured clothing that contrasts the background; avoid flips, jumps, fast spins, hand-occluding poses. Money-saver: **stack several motions into one ≤60 s take with ~2 s gaps** — one generation fee, split into clips in iClone.
|
|||
|
|
|
|||
|
|
## Getting it into ariki-game (short version)
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
/Applications/Blender.app/Contents/MacOS/Blender --background \
|
|||
|
|
--python tools/cc_retarget.py -- \
|
|||
|
|
--src "<iclone-export.fbx>" --out assets/quaternius/dancegen/<pack>.glb --name <ClipName>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Export from iClone with preset **Blender**, range **All**, **Preserve Bone Names (CC Base)** ON. The tool maps `CC_Base_*` → the shared 65-bone Quaternius skeleton, strips the mesh, and the GLB is auto-discovered by ClipCatalog as `<pack>/<ClipName>` (dirs: kevin/, mixamo/, dancegen/). Details, dance-JSON format, and the **unvalidated A-pose caveat** (first export needs an arm-orientation QA; workaround: FBX Advanced > Use T-Pose As Bind Pose): `references/ariki-integration.md`.
|
|||
|
|
|
|||
|
|
## Cross-cutting gotchas
|
|||
|
|
|
|||
|
|
- iClone 8 has **no animation-only FBX export** (CC4 does: FBX Options > Motion) and **no BVH export** (CC4 4.4+ does). No native glTF anywhere — route through Blender or Godot's ufbx.
|
|||
|
|
- Marketplace content needs a per-pack **Export License** to leave via FBX/USD; your own recordings/characters don't.
|
|||
|
|
- Video Mocap: keep plugin ≥1.02 (pre-1.02 double-charged points on re-open); Loop-enabled clips silently discard motion-layer edits — Flatten first.
|
|||
|
|
- MixMoves is gone in iClone 8 (Motion Director replaced it); AccuLips only works on CC-Standard/Gamebase characters.
|
|||
|
|
- ariki side: ASK Jeremy before launching the game; never use `*RM`/root-motion clip variants in dances.
