zwitschi 8ca403fd08 frontage: south block frontage, plus the placement bug it exposed
Adds the five remaining verified south-side buildings to the demo block
(6922, 6902, 6838 El Capitan Theatre, 6822 Budget, 6806-6820, 6800 Lee Drug)
exported in place from the OSM blockout and staged by the demo builder.

Adding neighbours exposed a pre-existing placement bug that could not be seen
while the hero stood alone:

- UE south is +Y (south sidewalk Y +718..+1447), but the hero facade sat at
  Y -1450 on the NORTH side and at X -12024..-9420, which is 26 m east of the
  6840 footprint (the frontage gap is X -14591..-12082).
- The two north-side buildings were on the SOUTH side, because their exporter
  mirrored Y.

Fixes: hero moved to X -13336 / Y +1307, inside its frontage gap; frontage and
north buildings export without a Y mirror (the FBX preset already lands
Blender -Y south on UE +Y south); player start and demo cameras moved to the
north sidewalk looking south; sun raised to pitch -62 so both frontages read
instead of the north side going to silhouette.

Screenshots re-rendered; the four demo views are marked needs-review because
the whole block changed.

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/
judge_screenshot.py Vision-model pre-check: judges a screenshot against an expected-scene description (--image + --expect, or --shots for every shot in the README). Reads OPENROUTER_API_KEY from .env (ignored). Optional helper — a human must still approve.
