# Spec: flat materials — the world without textures ``` Type: spec Status: IMPLEMENTED Status note: implemented 2026-07-08 (ROADMAP #29). The world renders as solid palette color under light in both modes: one named table (`mod palette` in crates/misaligned-bevy/src/main.rs) sources every world material; material families replace per-tile art; emissive is information (core > powered machines in amber, power hardware and live feeds in the cold signal — live feeds breathe via `flicker_feeds` — dead equipment dark, model state never glows); a blueprint floor grid is the one shader-level flourish. Tile PNGs and their load paths are deleted (assets/pixellab/ removed); criterion 1 is enforced twice — a unit test over the whole (tile, fog, part, live) material space and a fog_audit_3d assertion on every harness capture. fog_audit_3d passes (4608 tile entities, 37 pooled handles); material-render.md's criteria re-verified after the restyle. Adopted 2026-07-08 (design corpus: "Visual identity", flat-materials refinement). Supersedes the texture-treatment parts of material-render.md (which stays IMPLEMENTED — its camera, cutaway, fog-lighting contract, framing, and pooling all carry over unchanged); retires the Pixel Lab world-tile pipeline and ROADMAP #13.
