zwitschi 985dfcbac7 npc: AGigLineNPCPerson prefab + stable-named screenshots
- New C++ AGigLineNPCPerson: reusable NPC/pedestrian prefab built on the MPFB
  human. ACharacter capsule half-height 83 cm (total 1.66 m, head top ~1.66 m
  so a 1.60 m camera doesn't clip), the character skeletal mesh on the built-in
  mesh as the visible body (feet on Z 0), AutoPossessAI for 0.5.0 pedestrians.
  Staged at Z 0 in the review scene; captured as review-npc-prefab.png.
- AGigLineShotActor now names screenshots by stable camera name (no list-index
  prefix): inserting or reordering cameras no longer renumbers files or orphans
  the old ones. Re-rendered all review/demo shots with stable names.
- ue_build_review_map.py: chmod the target .umap before save_map (git marks maps
  444 on checkout, silently making save_map return False and dropping stages).
- Screenshots/README.md, ROADMAP, TODO updated for the prefab + stable names.
- DemoMap.umap rebuilt by the render pipeline (north buildings + demo cameras).

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/
