someone overnighted an interactive 3d web game with opus 5.5 + hi3d mcp, then dropped a ~65s browser playthrough — sailing ships, a rock fort, a kraken fight, chinese ui overlays. the clip is their real footage.

their 5-step pipeline (author claim):
→ gpt-image-2.5: multi-view concept + material refs
→ hi3d mcp: image → high-detail mesh
→ lod + draco glb so the page does not choke on huge face counts
→ three.js / webgl: loader, collisions, water shader, light, particles
→ webaudio for sfx + music

end card says all 27 models came from hi3d and the code from ai — their claim. hi3d v1.0 just went open source too (they say ~2m production assets). i have not rebuilt this stack.
