What it does
Physics Sim is an agent skill from arjun988/blender-skills. Rigid body, soft body, and destruction setups in Blender including constraints, cell fracture debris, and baked caches via MCP.
Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/destruction-pipeline.md`, `references/rigid-body-presets.md` and `references/sim-bake-checklist.md`).
It sits in Game Development. It works with Blender and Model Context Protocol. The repository describes itself as: 94 specialist Blender skills for Cursor, Claude Code, Kiro & Codex - MCP-powered production pipeline from blockout to engine export. The licence is MIT.
When your agent uses it
- Game Development work in your project
Example prompts
- “/physics-sim”
What it can do on your machine
Read from SKILL.md and the folder at commit 8f778d2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Physics Sim loads about 621 tokens when it runs, and up to ~796 if it reads all its reference files. Until then it costs about 35 tokens; SKILL.md has 187 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 cacheRigid 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 interpenetrationsSoft Body
- Prefer for simple soft props; use
cloth-simfor garments - Goal weights to retain shape
- Soft + collision object required
Bake / Export
- Bake to cache before render
- Alembic/USD for cinematic debris
- For games: bake key poses or flipbook; rarely live Blender physics
Constraints
MUST DO
- Apply scale; use simplified colliders
- Bake before final delivery
- Trigger destruction intentionally (frame)
MUST NOT DO
- High-res sculpt meshes as active colliders
- Unbounded shard counts
- Leave sims unbaked for final renders

To copy it by hand, put the folder in .cursor/skills/physics-sim, .gemini/skills/physics-sim, .github/skills/physics-sim and .opencode/skills/physics-sim in your project.
What does Physics Sim need to run?
SKILL.md names no scripts, command-line tools or credentials: Physics Sim is instructions for the agent only.
Does Physics Sim access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Physics Sim safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
