gig-line/TODO.md

# TODO.md

Actionable task list for this project. This file is the single, central place for planned work, claims, and progress marks. Milestone goals, scope, and release gates are in [ROADMAP.md](ROADMAP.md).

## Conventions

- Mark items **open** (`- [ ]`), **active/in progress** (`- [A]`, **deferred** `- [D]`), or **done** (`- [x]`). Keep the marks accurate.
- A level-three (`###`) section being worked on carries `- active - <sessionId>` (and optionally the branch name) in its heading. Remove the suffix when you stop.
- When all steps in a version section are done: write a `CHANGELOG.md` entry, then remove the version section from this file.
- Release gate: a version is tagged only on the owner's explicit go-ahead once its release checks pass, not automatically when the checkboxes close.

## 0.1.4 — Proper building façades (patch)

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).

### Patch tasks - active - 01a1b26b-3c94-707f-9665-2f6b4a79b564 (branch `facades-0.1.4`)

- [ ] **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.
- [x] **Define the façade module.** **Done 2026-11-09.** `Tools/facade_kit_build.py` builds the kit at the measured **4.96 m bay**: pilaster, sill, lintel, window bay (surround + inset glazing), shopfront bay (piers, glass, fascia), door bay (jambs, door, threshold), cornice and parapet + coping — 16 meshes, each exported through the shared `ue_metric_v1` preset with a JSON part report recording dims and evidence. `Tools/ue_import_facade_kit.py` imports to `/Game/Hollywood/Kit`. `Tools/ue_apply_facade_kit.py` assembles it from each building's own bounding box: **638 pieces placed across the six frontage buildings and both north buildings** (6922 = 13 bays × 11 storeys, theatre 8 × 5, TCL and Tussaud's 9 × 4, etc.). First pass put the window bays inside the solid wall (invisible) — the kit now projects the surround 3 cm proud with glazing 6 cm behind it.
- [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.
- [x] **Give OSM buildings a façade style.** **Closed as superseded 2026-11-09.** The Blosm `setupScript` route would build a second, competing façade system next to the module kit defined in the previous task. The kit already gives every staged building a real elevation (shopfront line, window rhythm, pilasters, cornice, parapet) from a single module, so a Blosm style script would duplicate it with a different vocabulary and a different set of assumptions. Revisit only if the kit cannot express a building the photographs demand.
- [ ] **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.
- [A] **El Capitan Theatre (6838) and the retail neighbours.** **Theatre trim done 2026-11-09:** `Tools/theatre_trim_build.py` builds the features that make the building read as itself — projecting marquee (12.0 × 2.60 m canopy at a 4.60 m soffit), illuminated fascia, recessed soffit, and a vertical blade sign (1.30 × 5.20 m) with frame and bracket; `Tools/ue_stage_theatre_trim.py` imports and stages it with site materials. Two bugs fixed en route: the trim was mirrored to the far side of the boulevard (Blender +Y is Unreal −Y) and the marquee sat 5 cm above the pavement (absolute Z where the pavement is 4.56 m above the datum). **Still open:** the retail neighbours modelled from the 18-frame reference set.
- [ ] Review every façade change with `Tools/render_screenshots.sh` before tagging.
- [ ] Tag `v0.1.4` and write `CHANGELOG.md` entry; then remove this section.

## 0.2.0 — MPFB player body, third-person camera, basic animation (weeks 7–9)

### Character setup

- [x] Generate MPFB human base mesh; export baked materials and deform skeleton. Done in bootstrap: idle-pose 19 158-vert human with a 137-bone standard rig, `Tools/mpfb_character_export.py` (now `--pose idle` + warm `make_diffuse`).
- [x] Import character into Unreal; validate skeleton, scale, and materials. Done: `/Game/Test/Character` — `SkeletalMesh` (138 bones), `Skeleton`, warm `M_Character_Export` material with baked `T_Character_Diffuse`.
- [x] Promote the character asset into a reusable NPC prefab (visible body, collision capsule, idle pose) ready for pedestrians (`0.5.0`) once the third-person body lands. Done 2026-11-07: `AGigLineNPCPerson` (see the 0.1.0 Character-development item); `0.5.0` reuses it as the pedestrian base.
