- Tools/facade_kit_build.py: the reusable kit (pilaster, sill, lintel, window bay, shopfront bay, door bay, cornice, parapet + coping) at the measured 4.96 m bay and 3.10 m storey; 16 meshes exported per object through the shared preset with a JSON part report recording dims and evidence. - Tools/ue_import_facade_kit.py: imports to /Game/Hollywood/Kit with complex-as-simple collision, so thin panes keep their real faces. - Tools/ue_apply_facade_kit.py: assembles from each building's own bounding box (bays = round(width/4.96), storeys above the ground floor) with shopfronts at street level, windows above, pilasters on bay boundaries, cornice and parapet at the top. Clears a previous application; unique labels per building. 638 pieces across six frontage buildings and both north buildings. Two bugs fixed en route: the window piece was modelled entirely at +Y so it sat inside the solid wall and was invisible (now projects 3 cm proud with glazing 6 cm inset), and clearing materials mid-build invalidated handles. Screenshots re-rendered; window rhythm now reads (edge transitions per row rose from flat to ~197 on the spawn view).

# 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/`](../Geo/README.md) 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 |
|
||
| `facade_kit_build.py` | Builds the reusable façade **module kit** at the measured 4.96 m bay: pilaster, sill, lintel, window bay (surround + glazing), shopfront bay (piers, glass, fascia), door bay (jambs, door, threshold), cornice and parapet + coping. Exports each piece with the shared preset plus a JSON part report (dims + evidence per piece). |
|
||
| `ue_import_facade_kit.py` | Imports the kit into `/Game/Hollywood/Kit/*` as static meshes with complex-as-simple collision; writes `/tmp/gigline/kit-import.txt`. |
|
||
| `ue_apply_facade_kit.py` | Lays the kit over a building's street face from its own bounding box: bay count = round(width / 4.96), storeys from the height, shopfronts on the ground floor, windows above, pilasters on bay boundaries, cornice and parapet at the top. Clears a previous application first; unique labels per building. |
|
||
| `generate_facade_textures.py` | Deterministic stdlib PNG generator for the facade maps (`T_StoneAshlar`, `T_Stucco`, `T_Asphalt`, `T_Concrete`, each `_BC` base colour + `_R` roughness). Pure-zlib writer, hash-based value noise, identical bytes on every run; `--size` and `--out` (`/tmp/gigline/textures` by default). `ue_build_demo_map.py` imports them into `/Game/Hollywood/Textures` and samples them world-aligned. |
|
||
| `ue_common.py` | Shared helpers for the Unreal commandlet scripts: `make_writable()` clears the read-only bit an LFS `.umap` checks out with (otherwise `save_map()` returns False silently), and `require_saved()` makes that failure explicit. |
|
||
| `fbx_export_preset.py` | The **single** FBX export preset (`ue_metric_v1` / `ue_character_v1`): metres→centimetres via `FBX_SCALE_NONE`, axis mapping east +X / north −Y / up +Z, `mesh_smooth_type="FACE"` (smoothing groups survive the import). Every Blender exporter imports it instead of copying the argument block; `preset_kwargs()` is bpy-free and unit-tested. |
|
||
| `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. |
|
||
|
||
## Gameplay QA
|
||
|
||
| Command | Purpose |
|
||
| --- | --- |
|
||
| `UnrealEditor <uproject> /Game/Hollywood/DemoMap -game -qaselftest` | Headless behaviour check: drives forward input for 2 s, then resets and pauses. Logs `GigLine QA: ... PASS/FAIL` lines and a final `RESULT`. Runs only with `-qaselftest`, so normal play is unaffected. |
|
||
| `-qaselftest` phases | Walk, reset, pause/unpause, a 16-row seam transect (0 holes), a ground-referenced wall probe (0/35) and a **facade occlusion probe** that fires sideways from the road centre and requires a blocking wall wherever a building is staged (0/9), plus a frame-time capture writing `Saved/Profiling/perf-walk-frametimes.csv` and logging `GigLine PERF:`. |
|
||
| `gigline.SetupLogs` cvar | Spawn/input setup logging, **off by default** (`DefaultEngine.ini [ConsoleVariables]`); enable at runtime with `gigline.SetupLogs 1`. |
|
||
|
||
## Reference and concept generation
|
||
|
||
| Tool | Purpose |
|
||
| --- | --- |
|
||
| `facade_detail_concepts.py` | Generates **frontal building plates** (whole elevation, entrance in its facade, or building with neighbours) from a local reference photograph with an image model (OpenRouter); close-up detail crops are deliberately not requested because they cannot be measured for proportion. `--list` is free and shows which studies have their reference present; `--all`/`--only <name>` generates. Never overwrites (writes `-v2`, `-v3`), writes a `.refgen.json` sidecar per image (model, prompt, source photo, SHA-256), and puts everything under `Art/reference/facade-details/` — gitignored, local-only, never shipped. Costs money per image, so it is never automatic. |
|
||
| `judge_screenshot.py` | (see Visual review) |
|
||
|
||
## Input injection
|
||
|
||
| Tool | Purpose |
|
||
| --- | --- |
|
||
| `input_emulation.py` | Pure-stdlib `ctypes`/`fcntl` driver that creates a virtual keyboard+mouse on `/dev/uinput`. The desktop treats it as real hardware, so it proves whether OS input actually reaches the game. Needs `/dev/uinput` writable (ACL on this host). |
|
||
| `input_test.py` | Injects a scripted sequence into the focused window: `--sequence move:2,look:3,jump:1,reset:1,pause:1,click`. |
|
||
|
||
## Tests
|
||
|
||
```bash
|
||
python3 -m pip install -r requirements-tools.txt
|
||
python3 -m unittest discover -s Tools/tests -t Tools -p 'test_*.py'
|
||
```
|
||
|
||
Stdlib `unittest`, no Blender/Unreal process. See [`tests/README.md`](tests/README.md): test the pure parts (encoding, classification, maths, parsing); if logic is buried in `main()`, extract it into a function so it can be tested.
