<brief_description>
Provides discrete level of detail.
</brief_description>
<description>
Automatically hides and shows [Spatial] children depending on the distance from the closest [Camera] to the [LOD] node. Child nodes that don't inherit from [Spatial] are ignored by the LOD system.
Children are shown in order with the first children shown when closest to the [Camera], and the latter children shown when further away.
The threshold distances for changes are determined by [member Spatial.lod_range].
For example, a first child with a range of [code]2[/code] will be shown from distance 0 to 2. A second child with a range of [code]5[/code] will be shown from distance 2 to 7, etc.
