Nanite Optimization
Materials & RenderingNanite virtualized geometry for rendering extremely high-polygon meshes without traditional LOD authoring, plus Virtual Shadow Maps and debugging tools.
/skill nanite-optimization What this skill does
Nanite Optimization gives you expert guidance on UE5's Nanite virtualized geometry system, which lets you render extremely high-polygon meshes without authoring traditional LOD chains. This skill covers when and how to enable Nanite, what mesh types it supports and its current limitations, how it integrates with Virtual Shadow Maps for high-quality shadows, and how to use statistics and debugging views to verify performance. Whether you are importing film-quality assets with millions of triangles or optimizing an existing scene, this skill helps you get the most out of Nanite.
Covers
- Nanite enablement per-mesh and per-project
- What Nanite supports and what it does not
- Nanite mesh import and configuration
- Performance characteristics and GPU requirements
- Nanite and Virtual Shadow Maps integration
- Fallback meshes for non-Nanite platforms
- Statistics and debugging visualization modes
- Scene-level optimization strategies
Does not cover
- Lumen Global Illumination → lighting-fundamentals
- Material creation → material-basics
- Level streaming and World Partition → level-streaming
- Foliage-specific Nanite usage → foliage-placement
How to use
Invoke directly in Claude Code:
/skill nanite-optimizationThis skill is also auto-detected when your prompt mentions Nanite, virtual geometry, mesh LOD, triangle count, mesh optimization, or high-poly intent. AgentUX will automatically activate Nanite Optimization when it recognizes you are working with high-density geometry or Nanite configuration.
Key Unreal Engine concepts
| Concept | Description |
|---|---|
| Nanite | UE5's virtualized geometry system that automatically streams and renders billions of triangles by dynamically adjusting detail based on screen coverage. |
| UStaticMesh (NaniteSettings) | The static mesh asset's Nanite configuration, controlling whether Nanite is enabled and how the mesh is processed into the virtualized format. |
| Virtual Shadow Maps | UE5's high-resolution shadow system that uses a virtualized page-table approach, designed to work hand-in-hand with Nanite geometry for detailed, consistent shadows. |
| Nanite Fallback Mesh | A reduced-polygon proxy mesh generated automatically for platforms or rendering paths that do not support Nanite. |
| r.Nanite Console Vars | Console variables for controlling Nanite behavior at runtime, including debug visualization, statistics, and performance tuning. |
