01
Install it
Run the command above, or upload the folder in Claude.
02
Ask naturally
Describe the task. Your agent loads cloth-sim when the request matches its description.
03
Name it if needed
If it does not trigger, say “use the cloth-sim skill”. In Codex, type $cloth-sim.
Cloth Sim
Garment blockout → sim → art-direct → bake. Stable pins. Engine-friendly caches/shape keys.
When to Use
- Dresses, capes, coats, flags, banners
- Character clothing that needs drape
- Baking sim to shape keys or Alembic/USD caches
- Pre-roll settling before animation export
Workflow
Garment mesh (quad-friendly) → Vertex groups (pin/collide)
→ Cloth modifier settings → Collision objects
→ Pre-roll settle → Sim pass → Art-direct fixes
→ Bake shape keys / cache → Cleanup → Export
Mesh Prep
- Quads preferred; even density on deforming areas
- Avoid long skinny triangles on folds
- Apply scale before sim
- Separate garment from body collider
Vertex Groups
| Group | Purpose |
|---|---|
PIN_Cloth |
Anchors (waist, shoulders, collar) |
COL_Ignore |
Optional non-colliding regions |
STIFF_High |
Belts, seams that should resist stretch |
Settings Starters
| Look | Quality | Speed | Bending |
|---|---|---|---|
| Soft dress | 8–12 | 1.0 | Low |
| Stiff coat | 5–8 | 1.0 | Higher |
| Flag/cape | 8–10 | 1.0–1.5 | Low–mid |
Tune mass and air viscosity for scale. Always run a settle pre-roll.
Bake Targets
| Target | Use |
|---|---|
| Shape keys | Game poses / few frames |
| Alembic/USD | Cinematic caches |
| Armature weights | If converting to deform-only |
Constraints
MUST DO
- Apply scale; define pin groups before long sims
- Collide against simplified body capsule/mesh
- Art-direct after sim (sculpt/corrective keys)
MUST NOT DO
- Sim hero cloth on ultra-dense sculpt meshes
- Skip pre-roll (starts mid-air / exploding)
- Export raw unstable caches

Tips for Cloth Sim
- • Start a fresh session after installing so your agent picks up the new skill.

- • It is part of a pack with 30 skills. Install only the ones you need with --skill to keep triggers precise.
- • If two skills overlap, mention the one you want by name.
