Level Of Details

Level of details section allows mesh decimation and generating LOD Group.

Maximum number of LOD Levels is 6.

For each LOD can be chosen the Decimation value, that is a percentage of vertex reduction compared to the LOD 0 (Main Mesh), mesh collider type and material it is rendered with.

If material type for the main mesh in the Material section is set to Splatmap, then for high level LODs it is advisable to use Basemap type material, as it uses less textures, is faster for rendering.

Mesh decimation tool used for vertex reduction doesn't affect vertices on the perimeter. This allows smooth edge connection for multi-chunk terrains and seamless LOD transition.

Note, Terrain To Mesh uses UnityMeshSimplifier (MIT License) for mesh decimation that may not be the perfect vertex reduction tool for the flat surfaces.
