## [0.1.2] — 2026-11-09
|
||
|
||
Scale and façade correction patch. Buildings and the hero elevation now match the reference photography and the cross-checked height data; no new gameplay scope.
|
||
|
||
### Added
|
||
|
||
- **`Tools/facade_detail_concepts.py`** — generates frontal building plates (whole elevation, entrance in its façade, building with neighbours) from a local reference photograph through OpenRouter image models. Spec-driven, never overwrites, writes a provenance sidecar per image, output stays in the gitignored `Art/reference/` tree. Local working material only.
|
||
- **`Tools/fbx_export_preset.py`** — the single FBX export preset (`ue_metric_v1` / `ue_character_v1`). Replaces the argument block that had been copied into six exporters.
|
||
- **Façade occlusion probe** in `-qaselftest`: 40 m traces sideways from the road centre at walking height, required wherever a building is staged.
|
||
- **Ionic detail on the hero**: base moulding at every shaft foot, a square abacus over every capital, and a 52-dentil cornice course.
|
||
- **Tool tests**: `Tools/tests/` now covers the input driver, height classification, the Mapbox cross-check, the concept generator and the FBX preset (49 tests).
|
||
|
||
### Changed
|
||
|
||
- **Storey height 3.2 → 3.1 m**, calibrated against Mapbox building data, with explicit overrides for three rear outbuildings; the block cross-check now reports 66 matches and no disagreements.
|
||
- **Hero colonnade 47.6 % → 53.1 %** of the 14.50 m elevation, inside the photographed 50–60 % band (thinner entablature and parapet).
|
||
- Blockout regenerated at the new storey height; frontage re-exported and re-imported (6922 42.1 → 39.1 m, El Capitan Theatre 20.0 → 20.5 m).
|
||
- FBX exports now carry smoothing groups (`FACE` instead of `OFF`), so round geometry is no longer faceted and imports stop warning.
|
||
|
||
### Fixed
|
||
|
||
- **Windows floated 1.44 m in front of the wall**, ahead of the colonnade; they now sit on the wall plane behind the columns.
|
||
- **Parapet medallions were flat discs lying on the coping** instead of discs on the parapet face.
|
||
- **The hero façade had no usable collision** — the player could walk through it. It is now complex-as-simple; auto-generated convex hulls were tried and rejected because they bulged into the street.
|
||
- **The three "guessed" block heights were never buildings**: two `building=roof` canopies and a transit shelter. They are classified as non-building volumes and the block now reports zero guessed heights.
|
||
|
||
### Verified
|
||
|
||
- Packaged build `-qaselftest`: walk, reset and pause pass; seam transect 1456 samples / 0 holes; wall probe 0/35; façade probe 0/9.
|
||
- Screenshots re-rendered for every change and approved by the owner.
|
||
|
||
### Known limitations
|
||
|
||
- Cornice dentil spacing, the base and abacus dimensions are recorded assumptions: the reference photography does not resolve them at our scale.
|
||
- Façade surfaces remain flat blockout materials; the textured pass is `0.1.4`.
|
||
|
||
## [0.1.1] — 2026-11-08
|
||
|
||
Collision-fidelity patch. No new scope: street geometry corrections and the QA tooling that measures them.
|
||
|
||
### Fixed
|
||
|
||
- **Sidewalk outer edge ledge.** The sidewalk stood the full 0.15 m kerb height above the DEM at both edges, leaving a 15.8 cm lip where the walk route crossed from terrain onto the south sidewalk. The upstand now tapers from full at the road-side edge to zero at the building-side edge; the north route's worst step fell from 15.1 cm to 6.9 cm.
|
||
- **Crossing ramps too steep.** The kerb-flush run was a fixed 1.5 m, giving ~8.7 % (measured 10–13 cm over 1.5 m). The run is now derived from a target grade (`--max-ramp-grade`, default 8 % ⇒ 1.63 m); the crossing steps 3.4 cm at 0.25 m sampling.
|
||
|
||
### Added
|
||
|
||
- **Walk pre-check improvements** (`Art/blender/site/site_assembly.py`): sampling coverage is independent of `--sample` (it previously shrank the route), and the report now prints the grade and the arc-length/offset **location** of the worst step, so a step can be located rather than guessed.
|
||
|
||
### Changed
|
||
|
||
- **Kerb height recorded as final** at 0.15 m modelled / 0.13 m as built — a standard 6 in LA kerb; neither the 3DEP DEM nor the reference photography can resolve it further (±2 cm), which is far below the character's 45 cm step height.
|
||
|
||
### Verified
|
||
|
||
- Site meshes rebuilt and re-imported (7/7, collision flags intact), DemoMap rebuilt, packaged Development build `EXIT=0`.
|
||
- `-qaselftest` on the packaged build: walk 761 cm in 2 s at steady Z 456, reset 0 cm, pause/unpause, transect 1456 samples across 16 rows / **0 holes**, wall probe **0/35** blocking hits.
|
||
|
||
### Known limitations
|
||
|
||
- One residual **13.4 cm surface step at s≈198 m** on the south sidewalk (8.0 cm at s≈251 m north). It is not a gap and is below the 45 cm `MaxStepHeight`, so it does not block traversal; the cause is a sidewalk-strip discontinuity near a centreline vertex, recorded in `Art/blender/README.md` as a smoothness refinement.
|
||
- Kerb radii at junctions, driveway aprons, drainage inlets and pavement joints remain unmodelled (unchanged from `0.1.0`).
|
||
|
||
Nothing yet.

||
## [0.1.0] — 2026-11-08
|
||
|
||
The first playable release: a walkable exterior demo of the **6840 Hollywood Blvd** (El Capitan Entertainment Centre) block in Unreal Engine, built on OpenStreetMap layout data and USGS elevation, with the hero façade and the verified block frontage staged on a walkable street.
|
||
|
||
### Added
|
||
|
||
- **Unreal project** (`Game/GigLine`) — C++ game module, Enhanced Input, packaged Linux build, and a `DemoMap` that a plain launch opens directly.
|
||
- **Walkable demo level** — terrain from the 3DEP DEM, Hollywood Blvd carriageway, both sidewalks and kerbs with collision, the designated mid-block crossing, and fixed daytime lighting (sun, sky light, sky atmosphere, height fog, pinned exposure).
|
||
- **Hero façade** for 6840 Hollywood Blvd — six-column neoclassical elevation with three genuine portal recesses, entablature, parapet and motto band (`Tools/hero_facade_build.py`, `Tools/ue_hero_facade_import.py`).
|
||
- **Block frontage** — the five verified south-side neighbours (6922, 6902, 6838 El Capitan Theatre, 6822 Budget, 6806–6822, 6800 Lee Drug) and the two north-side buildings (TCL Chinese Theatre, Madame Tussaud's) placed at their OSM positions.
|
||
- **First-person player** — `AGigLineCharacter`: 1.75 m capsule, 1.60 m eye camera, 4 m/s walk, mouse look, jump, reset (`R`) and pause (`Escape`); controls documented in `Docs/controls.md` and shown in-game.
|
||
- **In-game ODbL attribution** — `AGigLineHUD` draws the OpenStreetMap credit and licence line every frame.
|
||
- **QA harness** — `-qaselftest` (walk, reset, pause, seam transect, invisible-wall probe, frame-time capture) and `Tools/input_test.py` / `Tools/input_emulation.py` for OS-level virtual keyboard/mouse input.
|
||
- **Documentation** — setup, build, toolchain, licensing, ODbL review, release checks, and arc42 architecture docs.
|
||
|
||
### Fixed
|
||
|
||
- **All controls were dead in packaged and PIE builds.** The mapping-context generator wrote key bindings to the deprecated `mappings` array; UE 5.8 reads `DefaultKeyMappings.Mappings`, so the cooked game had zero runtime mappings and every key resolved to nothing. `Tools/ue_create_input_assets.py` now populates the current field.
|
||
- **"Fall-through" was an 8 m invisible box.** `Terrain_DEM` shipped only a bounding-box collision proxy; forcing complex-as-simple collision (`UGigLineAssetTools`) put the player on the actual street.
|
||
- **Reset returned the player to mid-air** — the start position is now captured on the first grounded frame.
|
||
- **Plain launch opened the engine template** — the default map now lives in `DefaultEngine.ini` and points at `DemoMap`.
|
||
- **Game target would not compile** — removed editor-only API use (`UStaticMesh::PostEditChange`, `AActor::GetActorLabel`).
|
||
- **`demo-north-buildings` screenshot** framed 85 % sky (camera 9.5 km west of the buildings); re-pointed to the building mass.
|
||
|
||
### Verified
|
||
|
||
- Both sides of the demo are traversable: 1456-sample seam transect, 0 holes, no blocking collision or invisible walls (`-qaselftest` on the packaged build).
|
||
- Placement and street scale match the reference photography and Geo measurements (road 24.3 m, sidewalk offsets 12.5/13.2 m, hero frontage 26.0 m).
|
||
- **414 fps average / p99 3.01 ms at 2560×1440** (Epic preset, TSR, VSync off, no frame generation) — far above the 60 fps target.
|
||
- Fresh checkout builds and packages with the documented external engine (UE 5.8.4).
|
||
|
||
### Known limitations
|
||
|
||
- Buildings other than the hero are flat blockout volumes; façade detail, materials and Blosm style scripts are planned for `0.1.4`.
|
||
- Kerb height (0.13 m as built vs 0.15 m assumed), kerb radii, driveway aprons and graded crossing ramps are deferred to `0.1.1`; crossing ramps are kerb flushes.
|
||
- One block only; no vehicles, NPCs, audio, or settings UI yet.
