Cinematic and game VFX in Blender including smoke, fire, particles, trails, and Geometry Nodes FX setups via MCP.

  • SKILL.md covers When to Use, Path Decision, Workflow and Effect Types, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Vfx Fx is an agent skill from arjun988/blender-skills. Cinematic and game VFX in Blender including smoke, fire, particles, trails, and Geometry Nodes FX setups 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/fx-timing-brief.md`, `references/game-fx-export.md` and `references/volume-domain-rules.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

  • “/vfx-fx”

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

Vfx Fx loads about 616 tokens when it runs, and up to ~806 if it reads all its reference files. Until then it costs about 30 tokens; SKILL.md has 189 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~616
With references · SKILL.md plus every file in references/, read only if the agent opens them
~806

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.

VFX / FX

Readable effects. Controlled simulation domains. Game sprites vs cinematic volumes.

When to Use

  • Smoke, fire, dust, sparks, debris
  • Magic / sci-fi energy FX
  • Muzzle flashes, trails, impacts
  • Geometry Nodes driven particle systems

Path Decision

Game real-time → Meshes/cards/ribbons + emissive mats (+ GN)
Cinematic     → Mantaflow / particles / GN → render → comp
Hybrid        → Sim in Blender → bake flipbooks/meshes for engine

Workflow

Brief (silhouette + timing) → Proxy emitter → Sim/GN prototype
  → Art-direct motion → Materials/lights → Cache → Render/comp or export

Effect Types

TypeBlender Approach
Smoke/fireMantaflow domain + flow; keep domain tight
SparksParticle Newtonian + collision + trail
DebrisRigid body shards (physics-sim)
Magic ribbonsCurves / GN extrude + emissive
Dust hitShort particle burst + soft sprites

Domain Rules (Volume)

  • Domain only as large as needed
  • Resolution from low → high after motion approved
  • Open borders intentionally; avoid wasted empty voxels
  • Collection: COL_FX_[Shot]

Naming

  • Emitters: FX_Emit_[Name]
  • Domains: FX_Domain_[Name]
  • Caches: document frame range in brief

Game Export Notes

  • Prefer mesh cards / GN instances over volume export
  • Atlas flipbooks when baking fire/smoke for engines
  • Keep pivot at logical spawn point

Constraints

MUST DO
  • Approve motion at low res before high-res sim
  • Light FX intentionally (emissive + key)
  • Cache before final render
MUST NOT DO
  • Huge empty domains
  • Unbounded particle counts
  • Skip timing brief (start/peak/end frames)
