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.

0.1.6 — Retail frontage (patch)

Suggested blender skills: references (reference-image-match), archviz, historical-worlds for the 1920s–1990s retail mix on this run.

Patch tasks

• Model 6822 Budget, 6806–6820 and 6800 Lee Drug from their own references. Art/reference/retail-neighbours/ holds 6800 and its neighbour (Gb321, CC BY-SA 4.0); Commons has nothing usable for 6822 or 6806–6820, so those two need photography before they can be modelled honestly. Do not substitute the El Capitan Theatre's 18-frame set — it would misattribute the façades.
• Review every façade change with Tools/render_screenshots.sh --verify before tagging.
• Tag v0.1.6 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 - active - session-5598ce7e-27e3-4c64-bb49-c04a4a31ee58 (branch anim-body-0.2.0)

• 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.
• Create basic idle/walk animation set. Done 2026-11-09: Tools/character_anim_build.py authors GigLine_Idle (60 f) and GigLine_Walk (30 f) at 30 fps from parametric cycles, and Tools/ue_character_anim_import.py imports them. Both AnimSequences verified in /Game/Test/Character: Idle 1.967 s, Walk 0.967 s. Limb axes were measured on the rig, not assumed — the probe rotated upperleg01.L 0.5 rad per axis and read foot.L, which showed X is the fore/aft swing (Y twists, Z abducts).
• [A] Verify animation plays correctly on the imported rig. Playback is broken and now measurable: the pawn's mesh is bound, both clips resolve, and the run logs GigLine: playing body clip Character_AnimHuman_rig_GigLine_Idle, but shot 5 still renders the body in bind pose (arms out). So PlayAnimation is called and the pose is not applied — next step is to check whether the imported clip carries bone curves at all (the FBX bake may be sampling only keyed bones) or whether the component needs SetAnimationMode(AnimationSingleNode) before SetAnimation/Play.

Camera and controls

• Add third-person camera following the player body. Done 2026-11-09: USpringArmComponent + camera on the capsule, boom 340 cm, lag 8, and the body is the animated skeletal mesh with the skin material. Review shot 5 (demo-third-person, Screenshots/README.md) shows the rig; the shipped default view stays first person.
• Add first/third-person toggle. V, via IA_ToggleCamera; the toggle swaps the active camera and the body's visibility. -thirdperson on the command line starts in third person so the review is reproducible.
• Add camera collision to prevent clipping through geometry. The spring arm's collision test (bDoCollisionTest, probe 12 cm on ECC_Camera) shortens the boom instead of letting the camera pass through a wall. Not yet exercised against a wall in a shot — the spawn point has open space behind it, so this is implemented but unproven.
• Document any input changes.
