Level Of Detail (LOD) Ranges
Level of Detail (LOD) is controlled by three properties in FlightGear, with the following default values:
Property | Default | Description |
---|---|---|
sim/static-lod/detailed | 1500 M | All objects (buildings etc) display withing this range.
|
/sim/static-lod/rough | 9000 M | terrain and non terrain objects will be displayed within this range, as follows:
The actual visibility range is randomly distributed from /sim/static-lod/rough to twice /sim/static-lod/rough, to reduce apparent "popping". |
/sim/static-lod/bare | 30000 | Only terrain after this point |
NOTE: The LOD ranges are only set during the scenery loading process. Therefore a scenery reload may be required to change the currently loaded tiles.
AI/MP ranges
AI/MP models (other models that aren't being flown/operated by the user) have two models. The first of these is the low detail (or fallback) model, which can be defined by an model developer (sim/model/fallback-model-index) as one of the values in $FGData/AI/Aircraft/fallback_models.xml. When there is no fallback model defined for a model the blue-yellow glider will be used.
There are three properties that control the operation of the LOD ranges for We also have the following settings used for AI models:
Property | Default | Description |
---|---|---|
/sim/static-lod/aimp-range-mode-distance | false | When true the distances in the following aimp- properties are considered to be the distance from the camera. |
/sim/static-lod/aimp-detailed | 400 (pixels) | This property works differently depending on the range mode.
|
/sim/static-lod/aimp-bare | 0 (pixels) | This property works differently depending on the range mode.
|
Model interiors
Property | Default | Description |
---|---|---|
/sim/static-lod/aimp-interior | 200 | range at which to display the model interior (when the model has defined a mesh as being the interior |
