zwitschi bc2e421d33 gameplay: designated street crossing — zebra markings, corridor cut, up-facing street

- street_mesh.py: continental zebra markings (0.5 m bars, 0.5 m gaps, 3 m
  band) at all three signalised crossings, triangles not quads (FBX SDK
  refuses to triangulate the crown-twisted quads), stripes +6 cm above the
  DEM so they stay above the road surface; winding flipped so every street
  surface faces up (road/sidewalks/markings were 100% down-facing and
  invisible in engine once the terrain stopped covering them).
- terrain_from_dem.py: cut a 10.7 m corridor around the Hollywood Blvd
  centreline so road, kerbs and sidewalks are not buried under the terrain;
  sidewalks themselves cover the transition band, walk-check stays at 0 holes.
- Blender builders save with a writability guard + fatal failure: *.blend
  is LFS-lockable and checks out read-only; a failed save previously left
  downstream steps building from stale files.
- ue_import_site.py: Crossing_Markings imports with no collision (paint on
  the road); ue_build_demo_map.py stages it and chmods the lockable .umap
  before saving (save_map silently returned False on read-only maps).
- ue_build_review_map.py: demo-crossing camera moved to the real crossing
  (s=130.1 m -> UE -24291,-1340) and fixed the ensure_writable path (was
  missing the .umap suffix, so the chmod never fired).

README.md

Tools

Repeatable helpers that drive Blender, Unreal, and the reference/asset sources. Nothing here is hand-run twice: every step that produced committed content has a script.

Geographic tools live in Geo/tools/ and the Blender-side builders live next to their output in Art/blender/*/; this folder holds everything that talks to Unreal, the network, or the repository.

Conventions

One script, one job. Every input is an argument; no interactive prompts.
Absolute paths where a tool crosses into a sandbox (Blender Flatpak, the Unreal commandlet). Those processes do not share the repo's working directory.
Unreal commandlets swallow print(), so each writes a result file under /tmp/gigline/. Read the file; do not trust the exit code alone.
No credentials, no writes outside the project by default.

Repository and assets

Tool	Purpose
`check-lfs.sh`	Fails if the `lfs` filter is missing or an LFS-tracked file was committed as a plain blob
`sibling_asset_audit.py`	Reads the sibling project's prop library from GLB headers into `Art/props/reuse-manifest.json`; copies nothing
`scale_test_export.py` / `ue_scale_test_import.py`	The 1 m = 100 uu scale test; the named presets `ue_metric_v1` live in these two files

Reference gathering

Tool	Purpose
`commons_fetch.py`	Wikimedia Commons: search, exact `File:` titles, or a whole category; writes a provenance `sidecar.json`
`page_image_fetch.py`	Resolves a web page's `og:image` and downloads it (Flickr, Commons file pages, photo blogs)
`addon_compat_probe.py`	Verifies MPFB/Blosm can load and generate headless on the pinned Blender

Blender content

Tool	Purpose
`hero_facade_build.py`	Parametric hero façade; emits a JSON report naming the evidence behind every part
`mpfb_character_export.py`	MPFB human, standard rig, baked skin, FBX export

Unreal import and level building

Tool	Purpose
`ue_import_site.py`	Imports the six site FBXs into `/Game/Hollywood/Site`, setting collision complexity per mesh
`ue_hero_facade_import.py`	Imports the façade and places it on the measured building line
`ue_build_demo_map.py`	Builds `/Game/Hollywood/DemoMap`: lighting, façade, site meshes, player start
`ue_build_review_map.py`	Rebuilds `Test/ReviewMap`, stages the shot camera list, and stages the demo-map views
`ue_create_input_assets.py`	Creates `/Game/Input` actions and the mapping context headlessly
`ue_character_import.py`	Skeletal import plus the material/texture chain Interchange skips

Visual review

Tool	Purpose
`render_screenshots.py` / `render_screenshots.sh`	Rebuilds the review map, runs the game, captures the shot list into `Screenshots/`
