zwitschi accf3a5306 lighting: fixed daytime rig, real surface materials, dynamic lights
Completes "Fixed daytime lighting and basic ambience" for 0.1.0. All 14
screenshots approved by the owner.

Lighting rig (Tools/ue_build_demo_map.py):
- Sun pitch -50 / yaw 120, intensity 4, warm (255/245/230), atmosphere sun light
- Sky light 2.6 with real-time capture, sky atmosphere, height fog (density 0.008)
- Unbound post-process volume with fixed exposure (min == max brightness) so a
  shot cannot wash out or crush to black depending on how much sky it frames
- Dynamic-only: r.AllowStaticLighting=False plus MOVABLE lights and mesh
  components, so the editor's "LIGHTING NEEDS TO BE REBUILT" warning no longer
  fires and nothing needs baking

Bugs found and fixed on the way:
- Blender diffuse colours do not survive the FBX -> Unreal import: every site
  material arrived white and the terrain arrived with WorldGridMaterial, which
  is what actually made the scene look blown out. The demo builder now creates
  and assigns M_Asphalt, M_Concrete, M_Ground and M_RoadPaint.
- Only one of the three crossings reached the game: each zebra band was its own
  object, so Blender renamed the duplicates .001/.002 and exact-name site
  assembly skipped them. All bands are now one Crossing_Markings mesh.
- Demo cameras: street-level sat inside the facade body (rendering its unlit
  back face) and the crossing camera aimed at the s=36.6 crossing instead of
  the designated s=130.1 (UE X -14956).
- The terrain had no material and imported as a bright default grid.
- Cleared a committed Android File Server SecurityToken (plugin disabled and
  shipping-excluded; the value must stay empty).

Docs:
- Screenshots/README.md: one consolidated table for all 14 shots with map,
  camera view and description; all approved.
- MEMORY.md: records the material-import, exposure, light_color struct,
  band-naming, camera-bounds and lighting-build traps.
- TODO.md: lighting item marked done.

Squash of branch gameplay-lighting-0.1.0 (PR #3).

Gig Line

A Linux-first Unreal Engine game about walking and driving through a real city. The first release, 0.1.0, is a walkable exterior demo around 6840 Hollywood Blvd / El Capitan Entertainment Centre, covering the south-side frontage between Highland Avenue and Orange Drive plus the north-side frontage within 50 m of the boulevard.

Status

0.1.0 is in progress. The workstation, engine, geo pipeline and project bootstrap are done and verified; a walkable DemoMap exists with terrain, street, sidewalks, kerbs and the hero façade placed from measured coordinates. Façades are still blockouts, and materials are flat colours — both are planned patches.

Current tasks are in TODO.md and the development plan is in ROADMAP.md; what was learned the hard way is in MEMORY.md.

Layout

Path Contents
Game/ Unreal project, configuration, source, game-ready content
Art/ Editable Blender sources, blockouts, terrain, street, hero façade, and a local (uncommitted) reference library
Geo/ Source manifests, permitted geographic data, and every geographic tool
Tools/ Unreal-side importers, level builders, and reference gathering
Docs/ Setup, toolchain pins, build and content pipeline, licensing, release checks
Screenshots/ Rendered review captures and their approval state

Getting started

git lfs install    # required: content, images, audio, and geo files are LFS-tracked
git lfs pull
Tools/check-lfs.sh # verifies the lfs filter is active and files are stored as pointers

The engine is installed outside the repository and pinned in Docs/toolchain.md. Setup is in Docs/setup.md; building and the content pipeline are in Docs/build.md.

Licensing

Code licence is an open decision (MIT proposed). Engine, art, and geographic data are licensed separately; see Docs/licensing.md. OSM-derived output carries "© OpenStreetMap contributors".
