== LOD Database ==
The '''LOD Database''' format stores both a given vehicle's LOD model as well as the model's rendering parameters.
LODs, or Levels of Detail, are lower-poly, lower-detail (hence the name) models that games use for objects that are far away from the player, to keep framerates smooth. BGVs contain 4 LOD Databases, which in turn each contain one LOD model of minimum (LOD 0), low (LOD 1), medium (LOD 2) and high (LOD 3) quality.
