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.

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.

0.2.2 — Skin and hair tuning (patch)

Patch tasks - active - session-5598ce7e-27e3-4c64-bb49-c04a4a31ee58 (branch anim-body-0.2.0)

• Restore the stride capture after the pose rewrite. The walk cycle started on a sine, zero at both the start and the middle of the cycle, so the deterministic capture kept landing on the two passing frames where the legs are together. Starting the cycle at maximum stride (cosine) fixed it with no other change; demo-third-person-walk is back as shot 8 and shows a genuine stride.

0.9.0 — Realistic buildings (weeks 31–34)

Suggested blender skills: archviz (real-world scale, façade composition, elevation read), references (reference-image-match and visual-match checklists — every building is judged against its own photograph), procedural-modeling + geometry-nodes (the façades system: bay module, cornice and coping profiles, storefront types as reusable node groups), materials (measured albedo and roughness per surface type), texture-workflow (baked AO/curvature/normal, decals for painted lettering and signs), uv-workflow (texel density and modular UVs), lod-pipeline (LOD chain per building), collision-proxy (UCX proxies so detail geometry is not the collider), lookdev (screenshot comparison loop), camera-cinematography (reproducing each building's reference angle), asset-optimization + unreal-export (pre-export validation, ue_metric_v1), qa-review (the gate before every review shot).

Façade system

• Extend the module kit beyond one order. Art Deco, neoclassical and streamline-moderne variants on the shared 4.96 m bay: alternate window proportions, spandrel and transom bands, and the way each order terminates at the roof.
• Build a profile library for cornices, copings, string courses, sills and storefront surrounds, so a building is assembled from named profiles rather than ad-hoc boxes.
• Storefront types: recessed entry, bulkhead and kickplate, mullion spacing, transom, awning/canopy brackets, and grille/shutter variants.
• Signage and lettering as decals. Painted wall lettering, blade signs and fascia panels become texture and decal work with a documented projection; 0.1.6 proved that lettering built as geometry plates cannot resolve at review distance.
• Document the system in Art/blender/README.md and the arc42 building block view.

Per-building models

Each building needs its own reference set; where none exists the blockout stays and the item says so.

• Hero façade (6840): raise to this pass's detail level — capitals and fluting, window rhythm behind the colonnade, parapet motto band and medallions.
• Hero façade (6840), entrance: doors at street level left and right of the central bay, as the photographs show, and correct positioning of the central-bay elements (column bases, entrance stairs, set-back entrance, door frames, banners and signage). Nothing may stand in front of the façade that blocks it — no awning, no temporary structure. Carried over from Screenshots/README.md, 2026-11-09.
• El Capitan Theatre (6838): marquee, blade sign, entrance and the theatre's own elevation from its 18-frame set.
• 6800 Lee Drug and 6806–6820: second pass on the 0.1.6 trim. Moved here from that patch because geometry cannot close them: wall lettering as a decal (a plate at 0.10 m still vanishes at 40 m), a moulded parapet profile instead of a two-tier box, richer corner-tower stepping, and the portrait panels reworked as textures rather than framed plates.
• Photography gap — 6822 Budget (deferred out of 0.1.6, blocked): no photograph exists; the single-storey 6.0 × 5.5 m volume cannot be read from the neighbour shot, so it stays a bare blockout until references are acquired. Record the sources checked in Geo/. Also re-shoot 6806–6820 and 6800 from the south sidewalk: the only reference is one oblique with a bus across Lee Drug's shopfront and a car across 6806's.
• 6902, 6922 and the remaining south frontage.
• North side: TCL Chinese Theatre and Madame Tussaud's façades from their reference sets.
• Reconcile every modelled height against Geo/tools/block_height_report.py and record the source per building.

Materials, UVs and performance

• Measured material library, including the hero's stone, which currently renders pale because it is a procedural graph and a generated texture set rather than a measured surface: stucco, painted render, ashlar, brick, terrazzo, glazing, bronze and steel trim, with albedo and roughness taken from the photographs rather than guessed; one Unreal material instance per surface type.
• Texel-density rule per building class, applied through modular UVs; lightmap UVs where required.
• LOD chain and collision proxies per building: UCX proxies for blocking volume, detail geometry non-colliding.
• Re-validate the 60 FPS floor at 1440p once the detail lands, and record the cost of the pass.

Release checks

• Every building with a photograph has a review shot measured against it, with silhouette and proportion deltas recorded in Screenshots/README.md.
• No building carries an unverified façade; blockouts without references are listed as such in TODO.md.
• Every building has a collision proxy and at least one LOD.
• No surface left on a placeholder material.
• THIRD_PARTY_NOTICES.md covers every photographic reference used in this pass.
• Performance target still met at 1440p.
• Tag v0.9.0 and write CHANGELOG.md entry; then remove this section.
