AR Model Integration with QR Code

I need a CAD model imported into a game engine compatible with Apple Vision, like Unity or Unreal. The model is textureless and needs market-sourced materials to mimic real-world textures, primarily polished metal and clear glass.

Key tasks:
- Import textureless CAD model (STL format)
- Apply polished metal and clear glass textures
- Create QR code/stand for in-room placement
- Develop a simple project that detects the QR code and overlays the AR model
- Ensure deployment capability on TestFlight

Ideal skills and experience:
- Proficiency in Unity or Unreal Engine
- Strong texturing and material application knowledge
- Experience with AR development and QR code integration
- Familiarity with TestFlight deployment
