|
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.

Determines the rate at which level of detail will be updated.

|
Higher priorities will update faster, but use more CPU.
