 Suggested blender skills: **procedural-modeling** + **geometry-nodes** (the façade module kit — bay, pilaster, cornice, parapet, window, shopfront, door — as reusable node groups), **archviz** (real-world scale and façade composition), **materials** (procedural brick, concrete, stone, render, glass — the ported generators), **texture-workflow** (AO/curvature/normal bakes and decals for the motto band and medallions), **uv-workflow** (texel density and modular UV layouts for the kit), **scene-assembly** (assembling kit pieces onto the fifteen block buildings), **lookdev** (screenshot-comparison loop until shading reads correctly), **historical-worlds** or **realistic-style** (1920s Hollywood Blvd neoclassical direction), **asset-optimization** + **unreal-export** (pre-export validation, `ue_metric_v1` preset), **qa-review** (final gate before the `Tools/render_screenshots.sh` review).

 - [ ] **Finish the Blosm blockout cleaning/detailing (moved from the deferred `0.1.0` item).** Import state: `Art/blender/blockout/blockout-2026-11-06.blend` (86 meshes, EPSG:26911, 0.0 cm affine residual) with cleaning tooling in `Geo/tools/` and `Art/blender/blockout/blosm_blockout.py`. To do here: (a) untextured roofs/facades → **Replace placeholder materials** below; (b) Blosm `setupScript` façade styles → **Give OSM buildings a façade style** below; (c) the 3 of 15 buildings lacking height data are the `0.1.2` placeholder-heights item.
 - [ ] **Define the façade module.** One set of reusable pieces (bay, pilaster, cornice, parapet, window, shopfront, door) at a fixed module, exported with the `ue_metric_v1` preset so every building assembles from the same kit.
-- [ ] **Replace placeholder materials.** Every blockout building currently carries Blender flat colours. Port the procedural generators from `Tools/sibling_asset_audit.py`'s sibling project (`brick_facade`, `seamless_concrete`, `asphalt`) and add stone, render, and glass, then wire them through Unreal material instances.
+- [A] **Replace placeholder materials.** **In progress 2026-11-09.** `ensure_material()` now builds masonry coursing (world-space course height + joint band + tint, corrected for UE's centimetre WorldPosition) and roughness variation; new `M_FacadeStoneShadow`, `M_FacadeGlass` (specular 0.62 ≈ IOR 1.5 without a refraction pass) and `M_FacadeBanner`; assignment is per **slot** keyed on the imported slot name (it was slot-0 only, which on the hero is the banner, so stone/glass/shadow were still flat). Hero: 4/4 slots, frontage and north buildings 2/2. Remaining: bake real texture maps (brick/stone/asphalt generators) rather than graph-only detail, and give the frontage shopfront line its own material.
 - [ ] **Give OSM buildings a façade style.** Blosm exposes `scene.blosm.setupScript` (`setup/neoclassical.py` is the example) so a building can carry a real elevation instead of a plain extrusion. Build one style script for the south frontage and one for the north.
 - [ ] **Hero façade detail pass.** Ionic capitals and fluting, the parapet motto band and medallions as geometry or decal, window rhythm behind the colonnade, and the three portal flights at their photographed proportions.
 - [ ] **El Capitan Theatre (6838) and the retail neighbours.** Model from the 18-frame 5472×3648 reference set; the theatre shares the measured 4.96 m bay rhythm with the temple.
