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.

0.1.1 — Collision fixes (patch)

Suggested blender skills: collision-proxy (UCX/UHX naming, convex hulls, simple collider meshes — the core of the authoring pass), qa-review (validation checklists, viewport screenshots, ship/no-ship verdicts for the audit), asset-optimization (pre-export validation of every collider). Note: these skills assume MCP-driven Blender; use them as method guides for the headless scripts.

Patch tasks

• Sidewalk outer edge against terrain. The pre-check measured a 15.8 cm step where a walk sample crosses from Terrain_DEM onto Sidewalk_South (Art/blender/README.md, s≈207 m). Mostly hidden by buildings; visible wherever the frontage is missing. Fix by extending the sidewalk mesh to meet the terrain, or by lowering the outer lip.
• Crossing ramp gradient. The kerb-flush transitions measure 10–13 cm over 1.5 m ≈ 10 %, steeper than the 8 % a real ramp uses (Geo/tools/street_section.py output, s≈33, 39, 126 m). Grade the three ramp openings properly.
• Collision authoring pass. Terrain and site meshes use complex-as-simple / BlockAll (forced by UGigLineAssetTools, verified 2026-11-08 with 84-sample transect). Remaining: simple convex hulls per building (currently using default collision). Record the final settings in Docs/build.md.
• Kerb height is an assumption. 0.15 m modelled, 0.13 m as built, and the 3DEP DEM cannot resolve a kerb at all. Check against the photographs and record the final figure.
• Audit and fix any collision gaps or fall-through geometry found in 0.1.0 in the engine.
• Regression-test traversal on both sides of the demo.
• Verify no new packaging defects.
• Tag v0.1.1 and write CHANGELOG.md entry; then remove this section.

0.1.2 — Scale and façade corrections (patch)

Suggested blender skills: references (reference-image-match and visual-match-checklist templates — measure the guessed heights and colonnade proportions against the photographs), archviz (real-world scale and façade composition discipline), camera-cinematography (reproduce the reference camera angles when comparing renders to photos).

Patch tasks

• Correct building scale and street proportions flagged against references.
• Refine hero façade details where reference photography shows discrepancies.
• Replace the placeholder heights. Three of the fifteen block buildings carry no OSM height and render at a guessed 6.4 m (Geo/tools/block_height_report.py). Measure them off the photographs and correct the blockout.
• Resolve the remaining unknown on the hero: the colonnade currently occupies about 45 % of the height against roughly 50–60 % in the photographs. Fix the vertical proportions.
• Tag v0.1.2 and write CHANGELOG.md entry; then remove this section.

0.1.3 — Packaging and setup fixes (patch)

Suggested blender skills: export-pipeline and unreal-export (scale/pivot/normals/materials/collision verification) if any packaging defect traces back to the Blender export presets.

Patch tasks

• Fix any packaging or build issues encountered in 0.1.x.
• Update Docs/ setup instructions for anything that changed.
• Tag v0.1.3 and write CHANGELOG.md entry; then remove this section.

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

• 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.
• 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.
• 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

• 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).
• 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.
• 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.
