# ROADMAP.md

Living roadmap for this project. This file is the single source of truth for current progress.

## Status at a glance — 2026-11-07 09:45

Workstation, geo pipeline, and engine validation are done. The art pipeline has a first blockout, terrain, and street in metres, in one shared coordinate frame. **Project bootstrap is complete**: `Game/GigLine` builds, packages, and both content-acceptance tests (static-mesh scale, MPFB skeletal character) pass. Remaining `0.1.0` work is geo detailing, asset production, gameplay, and release checks.

| Area | State |
| --- | --- |
| Workstation | Bazzite `45.20261105`, driver `615.78.08`, Vulkan good, `git-lfs`/`clang`/`cmake`/`ninja` installed |
| Tooling | Blender 5.2 + MPFB 2.0.18 + Blosm 2.7.28 working headless; QGIS 4.2.3; PROJ 9.9.0; Unreal 5.8.4 installed |
| Geo | extract, address + footprints + bounds, CRS + origin, 3DEP DEM, street profile, cross-sections — all verified and committed |
| Engine | 5.8.4 installed and validated: headless + Vulkan GUI editor launch pass on the RTX 5070 Ti |
| Blender | blockout (87 meshes), terrain, street (road/kerbs/sidewalks), site assembly — all in one frame, walk-checked |
| Reference | 72 images local, uncommitted; hero entrance located; inherited eight-step claim overturned |
| Unreal project | bootstrap complete: C++ project builds, blank Linux build packaged + launch-tested, scale test and MPFB skeletal character accepted |

**Next up:** model the hero façade and block frontage from the reference set, then first-person traversal on the site terrain. **Release gate:** `v0.1.0` is tagged only on the owner's explicit go-ahead once the release checks pass — not automatically when the checkboxes close.

**Open decision:** whether shipped builds carry a derived OSM database (ODbL posture).

## 0.1.0 — Local setup and walkable Hollywood block (weeks 1–6)

### Environment setup

Status detail in [Docs/setup.md](Docs/setup.md); pins in [Docs/toolchain.md](Docs/toolchain.md). The workstation audit is local only.

- [x] Update Bazzite using its supported mechanism; verify NVIDIA driver and Vulkan operation.
- [x] Register an Epic account and accept the Unreal license; obtain a pinned Linux engine build or build from Epic's authorized source repository.
- [x] Validate Unreal runs on Bazzite before asset production (not an officially supported distribution). 2026-11-07: headless `-NullRHI` smoke test **and** full editor GUI launch with the Vulkan RHI passed — device `NVIDIA GeForce RTX 5070 Ti`, Vulkan loader 1.4.350, `VULKAN_SM5`, map check 0 errors. Only benign log noise (Android Turnkey status, telemetry DNS failures).
- [x] Install the engine-required compiler/SDK, Git, Git LFS, and an editor; use Distrobox for isolated CLI dependencies where useful. clang 23.1.4 / cmake 4.3.0 / ninja 1.13.2 installed; this engine build bundles no Linux clang, so the system compiler is the toolchain. **Accepted 2026-11-07:** the first C++ game-module compile and link (`libUnrealEditor-GigLine.so`) succeeded with system clang.
- [x] Pin Blender, MPFB, Blosm, and QGIS versions; confirm add-on compatibility; record in `docs/toolchain.md`. Done: Blender 5.2.0 LTS, MPFB 2.0.18, Blosm 2.7.28, QGIS 4.2.3 with PROJ 9.9.0 (stale `lts` removed 2026-11-07), Unreal 5.8.4 finalized as pin after the editor GUI launch.
- [x] Create repository structure (`Game/`, `Art/`, `Geo/`, `Tools/`, `Docs/`) with LFS tracking and ignore rules applied.
- [x] Keep project and Derived Data Cache on SSD storage; reserve several hundred GB for engine, assets, caches, builds.

### Project bootstrap

- [x] Create a C++ Unreal project with Blueprint gameplay iteration and Enhanced Input. Created 2026-11-07 at `Game/GigLine/GigLine.uproject` (primary game module + default game mode, Enhanced Input plugin + input classes in `Config/DefaultInput.ini`); `GigLineEditor` target compiles clean with system clang (UBT: Result Succeeded).
- [x] Package and launch a blank Linux build. 2026-11-07: UAT `BuildCookRun` (cook + build + stage + pak, Development config) succeeded in 56 s; 1.1 GiB archive at `/run/media/system/DATA/Builds/GigLine` (outside the repo, uncommitted). `GigLine.sh` launched on the desktop session, created a Vulkan swapchain, and rendered 759 frames across a 60 s test. Known minor: one handled `PSOPrecache` ensure fires at exit only; not blocking, watch it in `0.1.x`.
- [x] Export one static mesh from Blender and import into Unreal; verify scale and materials. 2026-11-07: calibration scene (three 1 m cubes at origin / +10 m east / +10 m north) exported from Blender with preset `ue_metric_v1` (`Tools/scale_test_export.py`) and imported headless via `Tools/ue_scale_test_import.py`. Measured in UE: cubes exactly 100.00 cm, origin preserved, material imported. Axis mapping: **east → +X, north → −Y, up → +Z** (the Y mirror is inherent to the right-handed→left-handed conversion; importer handles winding).
- [x] Export one MPFB character with baked materials and deform skeleton; verify import. 2026-11-07: MPFB 2.0.18 generated human (19 158 verts, 1.66 m tall) + standard rig with weights (137 bones) + v2 skin baked to a 1024² diffuse texture (`Tools/mpfb_character_export.py`, export preset `ue_character_v1`). Imported headless (`Tools/ue_character_import.py`) into `/Game/Test/Character`: `SkeletalMesh` + 138-bone `Skeleton` + `Material` with the baked `Texture2D` assigned to slot 0. Quirks recorded: 5.8 Interchange skips materials for skeletal FBX imports (finished in script); Blender 5.2 dropped the FBX `armature_nla` option; the baked image needs `image.filepath` set for FBX to reference it.
- [x] Document initial setup in `Docs/`: engine install, project checkout, fresh-checkout build procedure. 2026-11-07: `Docs/setup.md` reconciled with reality (all engine/bootstrap items marked done with evidence); `Docs/build.md` completed with the fresh-checkout build, packaging, and headless-content-check procedures plus known engine quirks.

### Geographic data — active — gig-line-geo

Tools ported 2026-11-07: every geographic script now lives in `Geo/tools/` with `Geo/README.md` listing its purpose, and the Blender-side builders moved next to their outputs in `Art/blender/*/`, importing the shared helpers and the single unit conversion from `Geo/tools/osm_common.py`.

| Tool | Purpose |
| --- | --- |
| `osm_common.py` | parse `.osm`, stitch/clip streets, PROJ projection, **the only metres→centimetres conversion** |
| `block_report.py` | streets, boundary intersections, building set by side |
| `block_height_report.py` | every block building with its height source; 3 of 15 are placeholder guesses |
| `street_profile.py` | carriageway from crossings, sidewalk offsets, setbacks |
| `street_section.py` | DEM cross-sections, crown and gutters |
| `elevation_probe.py` | 3DEP relief sampling |
| `dem_stats.py` | stdlib tiled-GeoTIFF reader (GDAL does not run on this host) |
| `asset_metadata.py` | writes and audits the `<asset>.geo.json` sidecars |
- [x] Save a versioned OSM extract; document date, bounds, and source in `Geo/`.
- [x] Acquire separately licensed elevation data if needed. Needed and acquired: USGS 3DEP 1 m DEM in EPSG:26911, public domain, NAVD88, 984 KB committed (`Geo/manifests/2026-11-06-3dep-dem.md`); measured relief 3.94 m.
- [x] Download the 3DEP 1 m DEM for the demo bounds, reproject it to EPSG:26911 with the recorded origin and vertical datum, and record the source, clip bounds, and checksum in `Geo/`.
- [x] In QGIS, set a suitable local projected CRS (e.g. EPSG:26911) and record a local origin. EPSG:26911, origin and projected easting/northing are recorded in `Geo/manifests/local-origin.md` with PROJ 9.9.0 control points; QGIS 4.2.3 is installed for the DEM reprojection step.
- [x] Verify the address, building footprints, and demo boundaries for 6840 Hollywood Blvd against source data.
- [~] Import OSM blockouts through Blosm; clean and detail them in Blender. Imported 2026-11-06 and re-framed to EPSG:26911. Tooling for the cleaning pass is now in `Geo/tools/` (height provenance, block report) and `Art/blender/blockout/blosm_blockout.py`. **Still open:** 3 of 15 block buildings carry no height data and render at a placeholder 6.4 m, roofs and facades are untextured, and Blosm `setupScript` façade styles are unused. Earlier: (`Art/blender/blockout/blockout-2026-11-06.blend`, 86 meshes, scale 1:1 against OSM, re-framed into EPSG:26911 with a 0.0 cm affine residual); cleaning and detailing not started.
- [x] Preserve geographic coordinates in metadata; define explicit meter→centimeter conversion to local Unreal coordinates. Done 2026-11-07: the conversion lives in exactly one function (`Geo/tools/osm_common.py::to_unreal_local`) and every exporter must call it; `<asset>.geo.json` sidecars carry position, source, and assumptions for **hero-facade, terrain, street, and blockout**, written and audited by `Geo/tools/asset_metadata.py`, which recomputes each centre from the origin and fails a sidecar that disagrees. Props follow the same schema when they are imported. The frame is defined (`Geo/manifests/local-origin.md`: EPSG:26911, origin Hollywood × Highland, X east / Y north / Z up) and the ×100 conversion is now **verified** by the 2026-11-07 scale test, with the axis mapping recorded (north realizes as UE −Y). Left: build the production export preset for the actual site meshes using these settings.

### Review scene and player placement - active - gig-line-review-placement

Owner: this session. Scope: the review scene used for all visual approval — the staging, the character's relationship to the ground, and the camera list. Nothing in `Asset production` or `Gameplay` continues until these pass.

- [x] Put the character on the ground rather than floating. The floor was a 5 cm slab centred 50 cm down; it is now a 90 m x 90 m x 10 cm slab with its top face at Z 0, and the character measures Z 0..83 cm — feet on the plane (`Screenshots/README.md`).
- [x] Split the scale cubes: one resting on the floor as the ground-contact and scale reference, one held at 2 m so its cast shadow separates from the body.
- [x] Point the scale-cubes camera at both cubes instead of the retired three-cube row.
- [x] **Character placement shot**: `review-03-player-placement` shows the pawn (`AGigLineCharacter`) staged by `Tools/ue_build_review_map.py` with a cube behind it. Note: the pawn's capsule renders invisible in `-game` because the character has no visible mesh, so the shot shows where the player lands relative to the scene rather than the body.
- [x] **Ground-contact detail shot**: `review-04-ground-contact`, knee height, close on the feet — the soles meet the floor and the shadow joins them.
- [x] **Shadow-comparison detail shot**: `review-05-shadow-compare`, both cubes in one frame from a low angle; the floating cube's shadow is detached, the grounded one's touches.
- [ ] **Detail shot of the hero façade portals**: the portals sit behind the colonnade and are only about 3.4 m tall against a 14.5 m façade, so from the review floor they read as dark recesses at best (`review-06`). Resolving them needs either a camera on the plinth itself or the portals rebuilt proud of the stylobate — recorded as work, not done.
- [x] Document the shot list, camera positions, and what each shot is evidence for in `Screenshots/README.md`; nine shots, each with an approval line.
- [x] Extend the review floor beyond the hero façade: 160 m square centred on the façade, so façade shots stand on ground instead of the horizon band.
- [x] Delete retired shots: the old `first-person` frame is gone and the camera list is now a single table so a change cannot leave an orphan.

### Character development - open

Follow-on work on the player avatar, after the review scene passes. None of it is `0.1.0` scope unless a release check requires it.

- [ ] Decide what the `0.1.0` player is: first-person-only, or a body that is visible in third person. The `0.2.0` milestone adds the MPFB body and camera toggle; `0.1.0` currently ships a capsule with a camera and no visible body.
- [ ] Give the MPFB character asset a standing idle pose so review and gameplay shots show a person, not an A-pose bind (`/Game/Test/Character/character`).
- [ ] Bake a second skin tone or clothing layer, so the character does not read as a grey mannequin in shots.
- [ ] Add the character's collision capsule in the demo map and confirm the camera does not clip the head at the 1.60 m eye height.

### Asset production

- [x] Establish a consistent scale test, named export presets, and repeatable import settings. Scale test = the three-cube calibration scene (`Art/blender/scaletest/`, regenerable via `Tools/scale_test_export.py`); named export preset `ue_metric_v1` (FBX settings in that script); named import preset `ue_metric_v1` (`FbxImportUI` settings in `Tools/ue_scale_test_import.py`). Both scripts are the templates for production asset export/import.
- [-] Collect reference photography for manual façade work. Local only, never committed: `Art/reference/` is gitignored. **72 images in eleven folders**: hero façades to 4k, the El Capitan Theatre exterior series, premiere-night staging, Ovation Hollywood, the north side, and the Lee Drug neighbour. Gaps largely closed by the Flickr/web-search pass: the hero entrance is now documented (three portals with individual short flights — the inherited "eight steps, 12 m wide" is overturned), and the 6806–6822 retail run appears in an oblique 2013 frame. Still missing: a clean isolated frame of the door recess and a night frame of 6840 itself.
- [x] Download reference photography for the two north-side buildings inside the 50 m buffer — TCL Chinese Theatre (OSM way 424105908, 6925 Hollywood Blvd) and Madame Tussaud's (way 424105889, 6933 Hollywood Blvd). Done 2026-11-06 with `Tools/commons_fetch.py` against the Wikimedia Commons API: eleven frames in the local `Art/reference/north-chinese/` and `Art/reference/north-tussauds/`, provenance in each `sidecar.json`, nothing committed.
- [x] Model hero façade for the El Capitan Entertainment Centre site. **Second pass built 2026-11-07** (proportions recalibrated from the 2009 photograph: entablature 3.4 m, parapet 2.2 m, architrave and cornice bands, square pedestals — the first pass had 5.7 m of blank wall above the capitals and read as a warehouse). **First pass built 2026-11-07** (`Tools/hero_facade_build.py` → `Art/blender/hero/hero-facade-2026-11-07.blend` + JSON part report with evidence per part → `Tools/ue_hero_facade_import.py` → `/Game/Hollywood/ElCapitan/SM_HeroFacade`, 1892 tris, 4 materials, placed on the measured building line). Six columns at 4.96 m over the 25.75 m frontage, plinth, three portal flights (5 risers, not the old 8), entablature 2.2 m, parapet 1.6 m with motto band and medallions. **Screenshot review pending** (`Screenshots/review-04`, `review-05`). Next pass: portal recesses read from the street, banner and window placement, then materials.
- [ ] Model surrounding block frontage.
- [ ] Model simplified background buildings directly across Hollywood Boulevard.
- [-] Build sidewalks, roads, and collision meshes. Terrain, road, sidewalks and kerbs exist (`Art/blender/terrain/`, `street/`) and are assembled in `site/site-2026-11-06.blend`; collision and details (crossing markings, kerb radii, aprons) are not built. Ground must follow the DEM: 3.94 m fall along the block, ~2 % crown between the gutters at ±10–11 m from the centreline, north sidewalk higher than south. Kerb height is an unresolved assumption — the DEM does not resolve it (`Geo/verification/2026-11-06-cross-sections.md`).
- [ ] Materials and look development for all exported assets.

### Gameplay

- [-] First-person movement, mouse look, and Enhanced Input bindings. Implemented 2026-11-07: `AGigLineCharacter` (C++, 1.75 m capsule, 1.60 m eye camera, 4 m/s walk, mouse look in deg/s, jump) as the default pawn, with five actions and an 11-entry context in `/Game/Input` built by `Tools/ue_create_input_assets.py`. **Not yet confirmed interactively** — launch PIE on `Test/ReviewMap` and walk. Screenshot review pending (`Screenshots/README.md`).
- [ ] Collision, reset, and pause functionality.
- [ ] Walkable sidewalks and a designated street crossing. Crossing chosen: mid-block signalised crossing, OSM way 385648319, at 130 m along the block (`Geo/verification/2026-11-06-street-profile.md`).
- [ ] Fixed daytime lighting and basic ambience.
- [ ] Geographic attribution display ("© OpenStreetMap contributors" + license link).

### Repository publication

- [x] Remove confirmed private documents and bundled skills from publishable history while preserving local copies; validate all refs and LFS objects. Rewritten 2026-11-07; original history is in a separate private local backup.
- [x] Scan all reachable Git history and the publication changes with Gitleaks 8.28.0. Removed an Android File Server security token from history and disabled the unused server; the rescans found no leaks.
- [x] Review Unreal asset provenance via the generation/import scripts and inspect all 18 reachable Unreal asset versions for recognizable private-reference paths. No such paths were found; this is not a full binary-content audit.
- [x] Review OSM source distribution notices: original data retains attribution and licence metadata, and the repository links directly to ODbL 1.0.
- [ ] Review ODbL obligations for each shipped derivative database or produced work before public release.
- [x] Validate Gitea LFS support. The first push succeeded on 2026-11-07; a separate clone fetched all 26 historical LFS objects and passed integrity checks.
- [x] Commit and review the publication preparation changes before pushing. Initial publication commit: `101db3f`.

### Release checks

- [ ] Player can traverse both sides of the demo without falling through geometry. Blender pre-check passes: 0 raycast holes along both sidewalks and the designated crossing; worst seam step 15.8 cm at the sidewalk's outer edge (`Art/blender/README.md`). Engine traversal still to be tested.
