# Office Breach / 오피스 브리치

Original two-storey office architecture, room layout, stairs, collapsed concrete,
collision volumes, procedural surface artwork and baked lighting for Astra Attack.
Generator: `scripts/generate-office.py`. Full plan: `docs/map-designs/office/revision-10.json`.
Revision 10: ground bounding dimensions 34 × 47.32 m; floor spacing 3.6 m.
Ground footprint: 1,151.52 m². Only ground workspaces are shortened to 60%:
blue 17 → 10.2 m, red 14.7 → 8.82 m. Spawn rooms retain their size.
The 944 m² upper footprint, upper rooms and both stairs retain their geometry. Blue has a straight approach to the narrow B stair;
red reaches its side corridor through the project room. The direct southern B
shortcut is closed, while the long eastern bypass remains available.
A has two 1.8 m wide, 80-degree curved lower flights merging on a +1.8 m landing.
One 2.8 m wide upper flight turns west, away from the wall, and reaches +3.6 m.
The central broken slabs rise 3.52 m over a 6.4 m Z run (about 29 degrees),
with a 2.6 m width, 0.32 m slab thickness, fractured bearings and bent rebar.
The 57.5 m² collapse opening remains.
The two-storey layout SVG is generated from the same plan and curved collision
footprints as the game geometry.

- Used models: desk, chairDesk, computerScreen, computerKeyboard, table,

- Changes: recentered and scaled to metres; placed and rotated; flat MTL colors
  packed into the architectural atlas; triangulated and merged into static sectors;
  lighting baked offline. No runtime dependency on Kenney services or OBJ loaders.
- Small furnishings are decorative. Visible opaque desk bases, meeting-table
  bases and tall storage bodies provide simple solid gameplay cover. The 34
  2.12 m storage units include original steel cabinet geometry and Kenney wooden
  cabinet details. Their opaque cores block both players and standing-height fire.
  Chairs, foliage and computer accessories are not bullet-stopping cover.

Official Rainbow Six Siege Oregon / Skyscraper rework descriptions, previously
reviewed Consulate / Nighthaven Labs blueprints, and the
open-source Parpax map were researched as layout references only. Their geometry,
images and textures are not included. Ubisoft's public blueprints are not treated
as open-source assets. Research links and design decisions are recorded in
`docs/OFFICE_BREACH_IMPLEMENTED_09_2026-09-12_KO.md`.

- Changes: diffuse multiplied by a restrained baked AO term, encoded as WebP
  in the shared 2048 × 1024 surface atlas. World-projected 2 m UV tiles.
- Two runtime textures total; no normal/displacement shader, runtime lights,
  downloaded model loader, external requests, or dynamic debris physics.
- Fine edge chips and bent reinforcement are decorative, merged into existing
  static sectors. The major slabs, bearing masses and cover remain solid.

No Warehouse, Source-engine or commercial-game assets are included.
The map uses the existing game's static map file format.
