Authoring content for Nanite is no different than traditional meshes except that Nanite can handle orders of magnitude more triangles and instances than is possible for traditionally rendered geometry. On top of that, Nanite uses an entirely new system for rendering that data format in an extremely efficient way.Īll that is required for a Static Mesh to take advantage of Nanite is a flag to enable it. How a Nanite Mesh is different from a Static MeshĪ Nanite mesh is still essentially a triangle mesh at its core with a lot of level of detail and compression applied to its data. Nanite will continue to expand its capabilities and improve performance in future releases of Unreal Engine. For example, instance counts, triangles per mesh, material complexity, output resolution, and performance should be carefully measured for any combination of content and hardware. Loss of quality is rare or non-existent, especially with LOD transitionsĪlthough the advantages can be game-changing, there are practical limits that still remain.

Level of Detail (LOD) is automatically handled and no longer requires manual setup for individual mesh's LODs Use high-poly detailing rather than baking detail into normal map textures Now possible to directly import film-quality source arts, such as ZBrush sculpts and photogrammetry scans Multiple orders of magnitude increase in geometry complexity, higher triangle and objects counts than has been possible before in real-timeįrame budgets are no longer constrained by polycounts, draw calls, and mesh memory usage Nanite's data format is also highly compressed, and supports fine-grained streaming with automatic level of detail. It intelligently does work on only the detail that can be perceived and no more. Nanite is Unreal Engine 5's new virtualized geometry system which uses a new internal mesh format and rendering technology to render pixel scale detail and high object counts.
