From the SKILL.md

# Physics Sim Stable rigid/soft body setups. Motivated destruction. Baked caches. ## When to Use - Rigid body interactions and collapses - Soft body jiggle / rubber / simple soft props - Destruction and debris (cell fracture / pre-cut shards) - Pre-vis physics before VFX polish ## Workflow ``` Simplify collision meshes → Assign rigid/soft bodies → Constraints → Passive settings → Bake → Art-direct → Export cache ``` ## Rigid Body Quick Rules | Role | Settings notes | |------|----------------| | Active | Moving debris / props | | Passive | Floors, walls, heavy anchors | | Convex hull | Fast, approximate | | Mesh | Accurate, heavier | - Apply scale before sim - Use margin appropriate to scale - Collection: `COL_Physics_[Shot]` ## Constraints - Hinge / fixed / motor for mechanical links - Breakable constraints for destruction beats - Name: `RBCON_[Object]_[Type]` ## Destruction Approach ``` 1. Pre-cut shards (cell fracture or manual) 2. Island meshes as active rigid bodies 3. Passive shell until trigger frame 4. Animate trigger (force / keyframed activation) 5. Bake → cleanup interpenetrations ``` ## Soft Body - Prefer for simple soft props; use `cloth-sim` for garments - Goal weights

About this skill
What does the physics-sim skill do?

Rigid body, soft body, and destruction setups in Blender including constraints, cell fracture debris, and baked caches via MCP.

How do I install it?

Run `npx skills add arjun988/blender-skills --skill physics-sim --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From arjun988/blender-skills, a repository with 71 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
