Nanite & rendering

UE's renderer couples Nanite (virtualized geometry), Lumen (dynamic GI — see ue-lighting-and-lumen), and Virtual Shadow Maps into a coherent high-fidelity pipeline. This skill covers Nanite and the surrounding rendering systems an agent needs to configure and reason about.

When to use this skill

• Enabling Nanite on static or skeletal meshes in C++, editor scripting, or mesh settings.
• Diagnosing why Nanite does/doesn't apply (translucency, forward rendering, VR stereo).
• Choosing between TSR, TAA/TAAU, FXAA, MSAA and setting screen percentage.
• Configuring FPostProcessSettings fields in C++ or via a Post Process Volume.
• Rendering the scene to a texture (minimap, security camera, mirror, portal).
• Tuning r.* cvars for performance or debugging the render pipeline.
