Game artists LOD prefabs by importing the prefab into a game engine (e.g., Unity, Unreal), using the engine’s built-in LOD tools to create multiple detail levels, simplifying each level’s geometry/textures, and setting distance-based switching rules.
This optimizes performance—high-detail models show close to the camera, low-detail ones far away—reducing render load without losing visual quality.
For beginners, start with 2-3 LOD levels (e.g., full detail, 50% triangles, 20% triangles) using Unity’s LOD Group or Unreal’s LOD Setup. Test in-game to tweak switch distances for smooth transitions between levels.
