Aligned Half-Life office walls and ceiling
Research and asset choice
Perplexity was unavailable. Exa found the community VERC guide and original-game
material catalog; actual candidates were then inspected from the locally installed
Half-Life halflife.wad (not textures from the Black Mesa remake).

The VERC guide identifies green C1A0_LABW* wall panels and C1A0_C1 ceiling in
the early laboratory aesthetic. For the furnished OFFICE room we chose the original
FIFTIES family instead: FIFTIES_WALL14U (128x160, plaster above wood paneling) and
FIFTIES_CEIL5 (48x48, four square acoustic panels). The guide is a community
reference, not proof that this exact pair appeared in a specific original office.
Candidates were compared visually before selection. Original pixels are preserved.
tools/extract_office_surfaces.py exports just these two textures to
assets/textures/office/, plus source WAD and texture-lump SHA256 manifest. It
never changes Steam files or re-extracts zombie assets.

UV layout
The old generic world-space triplanar mapping did not distinguish wall motifs from
ceiling motifs. room.gd now retains BoxMesh vertices/normals/indices but rebuilds
wall/ceiling meshes as ArrayMesh with explicit room-space UVs. Existing collision
boxes and placement remain untouched.
- Walls: U advances clockwise along the room perimeter at one texture per 4m. V runs floor-to-ceiling once, inverted so the wood is BELOW the plaster. Equal density128px/4m =160px/5m, no aspect distortion or repeated vertical trim bands. All window segments share the same coordinate origin; segment size does not reset the mapping. The 72m perimeter is18 full repeats, so all corners close. V uses a half-texel inset at the floor/ceiling to avoid exact0/1 wrap-edge sampling.
- Ceiling: XZ planar UVs with a shared origin at(-9,-9). One48x48 image covers1.2m and contains two panels per axis, so each panel is0.6m. The18m ceiling spans15x15 texture repeats (30x30 panels). No per-face rotations or arbitrary local scaling.
- Linear mipmapped anisotropic filtering and U tiling remain enabled.
- Floor keeps its existing texture/projection. Furniture, lighting and gameplay are unchanged. The old wall/ceiling PNGs are retained but no longer used here.
Verification
tools/test_office_uv.gd: seventeen explicit-UV surfaces, no triplanar on office
materials, shared UVs across window segments,4m wall period, wall corner phase
continuity/full-perimeter closure, and ceiling15x15 tiling. PASS headless and real
GL Compatibility. Images /tmp/zombie-office-uv-{0,1,2}.png inspect opposite walls
and ceiling; first two use a TEMPORARY inspection light, last uses actual gameplay
lighting. The inspection light exists only in the test, not in the game.
Existing resource-in-use warnings at test shutdown remain.
