• Local input: doom_e1m1_hangar_-_map.glb.
• Production file: models/e1m1.glb, 335,764 bytes. Byte-for-byte copy; no texture, palette, UV, or material changes.
• SHA-256: 98d80e757d257d435dd5cedee39fb737b8e834bd872288dbe6d720f17adf58bc.
• Runtime adaptations: uniform scale of 1/64; origin at the verified spawn; individual door surfaces held open; the ambush platform lowered; the secret lift animated; camera-intersecting ceiling patches temporarily hidden. These are exploration/view adaptations, not original DOOM gameplay.

Doom Slayer head

• Declared license: CC BY 4.0, from the supplied toy GLB metadata.
• User-prepared input: doomguy-head.blend, containing the separate Doom Guy Head mesh. No new body separation was required.
• Source blend SHA-256: 8897b228f47133f52deee683d6a0c26c9fcf8087b8a3c936afad969a2bf5b954.
• Preparation: exported the selected head in its active scene using Blender MCP. Preserved geometry and UVs; exported the existing Principled material as metallic/roughness plus supported specular/IOR extensions. Converted embedded texture payloads to JPEG at quality 85 where alpha permitted. No source blend save or source mesh edit.
• Production file: models/doom-slayer-helmet.glb, 1,948 triangles. Runtime normalization sets attachment size, center, and facing.

Engine and authored content

Three.js 0.186.0, MIT license, is vendored locally with matching GLTFLoader, BufferGeometryUtils, and SkeletonUtils. See lib/THREE-LICENSE.txt. The fly body, controller, brain illustration, and scene code are authored for this website. The illustration is not a biological connectome or a trained neural simulation.

Navigation geometry was cross-checked against E1M1’s shareware sector and player-start records using a temporary reference WAD from https://github.com/ebenupton/doom/blob/master/DOOM1.WAD. The WAD is not distributed with this site. The GLB is reflected on X relative to WAD coordinates: player start (1056, -3616), angle 90°, maps to GLB (-1056, 0, -3616), facing +Z.
