Use when shading an asset in Maya with Arnold: OpenPBR or aiStandardSurface materials, hooking up Substance Painter or UDIM texture sets, color spaces (sRGB, Raw, ACEScg), a normal map that looks wrong, displacement with black holes or faceting, skin SSS, chrome and metals, glass or crystal, car paint, aiStandardHair, porting Standard Surface to OpenPBR, or a lookdev turntable with chrome and gray balls. Also when textures render washed out, too dark or plastic in Arnold.
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
# Look development in Maya 2027 (Arnold) Expert look dev is a material that holds under any light a lighter throws at it: correct data in (every map in the right color space through the right plug), physically meaningful base values (measured metal colors, glass tinted by depth, scattering at real scale), then deliberate imperfection, judged on a neutral turntable with reference balls, one change per render. Nothing is done before a render has been looked at. 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_shade.py`](scripts/mx_shade.py) is **not yet run in Maya**: 122 offline checks passed; the Maya layer ran against a fake `maya.cmds` (logic only). Once Maya is installed: `tests/code/maya-lookdev/run_all.sh`, then fix the attribute tables from `probe_lookdev.json`. ## Stance (the expert delta) …

How to install
mdr add scenario-labs/skills/scenario-maya-lookdev@sha256:07f490a429405c3cThe 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.
