Roomcraft — author a whole virtual place together by describing it
An opt-in XR Blocks addon that turns a prompt into editable 3D content, composing catalog assets with procedural primitive-part designs. Scenes are refined in place through text, Gemini voice or direct manipulation — alone, or with several people at once. A four-letter room code opens the same scene across headsets, phones and laptops, sharing authoring, dragging, selection, presence and peer voice kept separate from Gemini, with animation running from a common timeline so late arrivals catch up. Optional virtual worlds add ground, sky, lighting, ponds, paths and seeded plants; characters and creatures can be added and set moving, objects can take bounded swing or spin animation, and the whole scene supports selection, undo/redo and JSON export. It composes and edits a scene graph — not text-to-mesh generation, and not generated JavaScript.
Runs anywhere XR Blocks does, including the desktop simulator — not a headset-only app.
