Use when lighting or rendering in Maya with Arnold: a product hero shot, a character close-up or a sequence (master and shot lighting), key, fill and rim placement, "the Arnold render is noisy" or fireflies, render settings and time budgets, AOVs, light groups and EXRs for Nuke, OIDN or noice denoising, ACES or OCIO color, renders that look flat or too dark, Render Setup layers, batch or command-line renders, or judging a lit frame like a lighting supervisor.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Lighting and rendering in Maya 2027 (Arnold) Expert lighting is a story decision made measurable: know where the eye must land, shape every form with one dominant light, structure values back to front, prove it with light groups and numbers before the eye signs off. Rendering is engineering: find the noise in the AOVs before touching a sampler, deliver scene-linear EXRs whose passes rebuild the beauty, judge through a tone-mapping view. 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):** [`scripts/mx_light.py`](scripts/mx_light.py) is **not yet run in Maya**: 138 offline checks passed (python3 + numpy); the Maya layer ran only against a fake `maya.cmds`. Once Maya is installed: `tests/code/maya-lighting-rendering/run_all.sh`, then fix names from `probe_lighting.json`. ## Stance (the expert delta) - **Story and target first; brighten by darkening.** "What is the story I am trying to tell?" before …

How to install
mdr add scenario-labs/skills/scenario-maya-lighting-rendering@sha256:9f225300b627f1f4The line at the top of this page pins the label git:20261017.88ccf82, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
