I need a real-time architectural walkthrough built completely in Unity. The priority is 3D visualization, so you will start by designing the actual building models from scratch—there are no ready-made plans for you to import. Once the geometry, materials, and lighting are in place, I want an optimized Unity scene that I can compile and run on desktop and VR without frame-rate drops. You’ll receive a short brief with room dimensions, style references, and functional requirements; from that you will create the full set of meshes, textures, and prefabs, then set up lighting, post-processing, and basic user navigation inside Unity 2022 LTS (or later). If your workflow relies on Blender, 3ds Max, or SketchUp before export, that’s fine, but the final hand-off must sit cleanly inside a Unity project. Deliverables • Custom architectural models (FBX or native Unity prefabs) • Complete Unity project folder with scenes, materials, scripts, and lighting settings • A build guide or brief read-me so I can open, edit, and compile the project myself The door is open for future AI-driven or mathematical features, yet for this first milestone I’m only measuring success by the visual fidelity, file organization, and performance of the finished Unity scene. If that sounds like your specialty, let’s set up a quick call and get started.
