What it does

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.

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, load it with skill_get (Scenario MCP) or ask the user to install it (https://github.com/scenario-labs/skills#install); 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 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.
