scenario-maya-fx

scenario-maya-fx is a skill for Claude Code from scenario-labs/skills. It costs 123 tokens per session (4,480 once invoked), scanned A, original, MIT.

A Maya workflow for simulated and procedural effects, including cloth, particles, smoke, fire, liquids, snow, sand, and graph-based effects. It covers Maya systems such as Nucleus, Bifrost, nParticles, and MASH, along with cached results.

In plain words
What is it for?
Use it to create or troubleshoot capes, skirts, flags, garments, smoke, dust, mist, fire, liquids, and other Maya effects driven by simulation or procedural graphs.
Why use it?
It helps prevent unstable simulations caused by incorrect scene scale or unsuitable inputs. Checking the cached simulation for stretching, collisions, popping, and convergence is more reliable than judging only a live preview.

About the project

Scenario Agent Skills is a collection of instructions that teaches AI coding agents to create images, video, audio, textures, skyboxes, and 3D assets through the Scenario MCP server, an interface to Scenario’s generation tools and custom-trained models. It serves game, entertainment, marketing, and other creative work, and also includes workflows for digital content creation software and game engines. The catalogue entries are these skills, along with plugins, commands, agents, instructions, settings, and hooks for using Scenario or driving supported creative applications.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scenario-maya-fx scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/mx_fx.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Maya FX (Nucleus, Bifrost, MASH, caches)

An expert FX TD fixes scale and inputs before touching a knob, changes few settings one at a time, never judges a live solve, and proves the result on the cache in numbers (penetration, stretch, pops, convergence) and in renders from the shot camera. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.

REQUIRED BACKGROUND: scenario-maya-expert (execution channel, review loop, 2027 version traps).

Status (2026-09-24): Maya 2027 is not installed. The pure-Python layer of scripts/mx_fx.py passed offline (tests/code/maya-fx/test_fx_offline.py); every Maya call is not yet run in Maya; names marked [verify] are answered by job_00_fx_probe.py (python3 tests/code/maya-fx/run_all.py).

Stance (the expert delta)

  • Scale before anything. Nucleus and Bifrost compute in meters whatever Maya's unit: Space Scale and scene_units_in_meters 0.01 in a cm scene, or a 182 cm character is 182 m to the solver (2027 Help; SARKAMARI [00:29:22]; Stamatelos [00:30:21]). MPM detail_size is in meters, so a unit change silently changes resolution (Gast [00:07:29]).
  • Never simulate the production mesh. Duplicate the skinned body and garment, drive the duplicates with a blend shape at weight 1, hide the originals (SARKAMARI [00:10:04]).
  • Give the solver a clean start. Hold 25 frames, blend 25 frames into the first pose, action at 0, Nucleus start -50 (SARKAMARI [00:05:26]); Julan: A-pose at 0, walk by 24.
  • Substeps before stiffness. Collision iterations below the substep count do nothing; high stretch resistance at low substeps cannot converge (2027 Help, Tips). SARKAMARI's remaining penetration vanished at 30 substeps and 35 iterations, with Space Scale moved to 0.25 in the same pass [00:29:22] [00:29:57].
  • Cache, judge the cache, render the cache. nCache before every playblast; the render scene holds Alembics only (SARKAMARI [00:19:32], [00:40:07]).
  • Bifrost fails silently. Unpulled outputs are never computed, empty arrays are valid data, mismatched arrays truncate (Jason E3aOt5wuvoo [00:22:49]; Nordenstam [00:38:11]; graph doc). A sim solves only forward from its own start frame: default 1, and it must exist in the timeline (sim guide; Nordenstam [00:56:23]).
  • Do not simulate what you do not need. Start a snowball at the collider with its impact velocity (Gast [00:55:18]); layer garments through Alembic colliders (SARKAMARI [00:32:06]); coarse background sources (Stamatelos [00:21:25]).
  • One change per run, logged (Jason cd3HgvM8sXg [00:21:43]); mx_fx.set_attrs returns the log.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Use this Skill when a game plan needs a single-subject concept image, a character reference cleaned for image-to-3D, or a front-facing transparent T-pose image for downstream character reconstruction. T-pose generation is an image-generation and image-editing task; it is not a separate asset category.

Use this Skill when a game plan requires dialogue, voice lines, sound effects, foley, ambience, or other offline WAV assets. This is asset generation, not a runtime audio-playback contract; use the selected engine context after an asset has passed review.
