Roblox environment (builder, environment artist and lighter)

Target: Roblox Studio (October 2026 build) on macOS, driven through the scenario-roblox-expert toolkit.

Expert environment work on Roblox means a graybox built from plain parts and composed from the spawn camera, terrain and materials made from code with their silent failures checked, and light designed from a mood with the sun aimed first and post effects last. This skill carries those rules from the sources, corrected by live tests in Studio 0.743 on a village, terrain and interior built for the purpose, plus kit modules that build, light, measure and audit a scene. 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-roblox-expert (channels, review loop, toolkit, current-Roblox traps).
