Playable apartment built in 5 hours with Claude and Unreal

rewind@rewind02

built a playable apartment in 5 hours with Claude Opus 5.5 + Gpt-6 Astra + Tripo + Unreal..

a sunny apartment with a study, a hallway and a kitchen

the trick is letting opus run the whole asset pipeline. here’s the workflow:

- step 1: have opus list every prop the scene needs: desk, monitors, shelves, key, tin, fuse
- step 2: astra generates a reference image for each prop, plus masks and textures
- step 3: opus sends each reference to tripo through the api and collects the 3d models
- step 4: opus converts everything for unreal and imports it room by room
- step 5: light it with sun through the blinds, and keep the rooms small and dense
- step 6: add simple mechanics: pick up, inspect, open drawers, use items on doors
- step 7: chain the puzzle: study key > locked door > spare fuse > four-dial tin

let opus be the manager, not the artist. it calls the tools that make the assets and keeps everything moving
