IamEmily2050 shares a massive structured prompt for Gemini 4 Argon / Antigravity that builds a photorealistic, playable 3D 1974 modular analog synthesizer plus vinyl turntable studio and renders a 2-minute 1080p60 showcase video. Highlights:
- Pipeline: Gemini 4 as director, headless Blender 5.2 (bpy) for editable assets, Nano Banana + Python Sobel/PBR synthesis for 16 texture maps, Three.js for 60 FPS interaction, Web Audio API for live sound, FFmpeg for encoding.
- Contract-driven: schema-validated contract. (rack dimensions, 16 knobs, 12 patch jacks, 25 keys), world. (64 entities, camera presets) and progress. coordinate the work.
- Verify first: export a calibration knob glb and validate picking/audio before building the full scene; grain-direction UV mapping and bevel rules are spec'd in detail.
A reusable workflow template for large multi-tool agent 3D projects.
