How to export a heavy architectural 3D rendering into a smoothly navigable VR walkthrough for clients?
Start by optimizing the architectural model: bake lighting into textures rather than computing it in real-time, reduce polygon counts using LOD (Level of Detail) techniques, and compress textures. Export as GLTF/GLB for web-based VR or FBX for Unity/Unreal Engine. In the VR runtime, implement teleportation-based navigation (rather than smooth movement which causes motion sickness) and ensure a consistent 72+ FPS for comfortable viewing.
