Nanite is a virtualized micropolygon geometry system introduced in Unreal Engine 5, designed to handle massive amounts of geometric detail and complexity in real-time 3D environments. In platforms like Arcane Mirage, Nanite technology enables developers to import, render, and interact with highly detailed 3D models and environments without traditional polygonal limitations. Nanite utilizes virtualized geometry data and GPU-driven rendering techniques to achieve photorealistic visuals, dynamic lighting, and interactive simulations at unprecedented scale. By leveraging Nanite, developers can create immersive experiences, architectural visualizations, and virtual productions with cinematic-quality detail and realism, pushing the boundaries of real-time rendering and content creation in Unreal Engine.
