# Istanbul — Süleymaniye mobile district

Original illustrated realistic environment for a mobile-game production test. One Süleymaniye-inspired landmark, ten Ottoman-inspired houses, two navigable streets, source assets and a real Blender camera trailer.

The delivered scene contains 109,947 placed triangles, ten final house exteriors, a shared three-map 2K PBR atlas, conservative LOD1 and collision proxies. See `docs/final-review.md` for the completed production checks and integration limits. The later `docs/lod-review.md` supersedes the initial export verdict in the independent review.

## Source structure
- `references/`: authentic photographic inputs, generated concept sheets, prompt receipts, source attribution and architectural corrections.
- `review/`: reference review page with feedback export.
- `scripts/`: reproducible Blender authoring, render, export and independent audit tools.
- `textures/`: shared image PBR atlas and provenance.
- `assets/`: packed Blender source, GLB LOD0, LOD1 and collision meshes.
- `renders/`: actual 3D stills and trailer.
- `docs/`: technical contracts, measured audits and final visual review.
- `delivery/`: source package and public presentation landing.
- `skills/`: one reusable production skill and five stage-specific subskills.

The public archive preserves generated reference sheets and source attribution. Three research photographs without verified redistribution permission remain only in the local project; their URLs and metadata are included in the downloadable package.

## Scope and interpretation
The UNESCO-listed Süleymaniye quarter is documented at https://whc.unesco.org/en/list/356/ . The landmark is an artistic reconstruction from photographs. Houses and street positions are original composition choices; this is not a surveyed or historically exact digital twin.

The working image model available in Loremax is GPT Image 2 (`gpt_image_2`). The user's requested label “2.5” is not present in the workflow model options. Generated concepts guide visual development; the final images and trailer are rendered from the delivered 3D scene.

## Mobile constraints
Target: fewer than 150,000 triangles for LOD0, shared 1–2K image textures, simple metallic/roughness PBR and optional LOD1. Blender cinematic lighting is included in the source; the mesh-only GLB expects the host game's lighting and environment configuration. Texture-memory estimates and asset counts do not establish a mobile frame rate.

## Rebuild
Validated with Blender 5.2.1 LTS, Python 3.12 and FFmpeg. Invoke background Blender with `--python scripts/build_scene.py`. Rendering and export scripts can be rerun from the saved scene. Exact commands and engine import notes are in `docs/rebuild-and-import.md`. The final trailer is 24 seconds at 1920×1080, 24 fps, rendered from the source camera timeline.
