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 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.
