Element/Building
The building class represents static, 3D models in the GTA world. Examples of buildings include building models, roads, and terrain. Buildings, unlike objects, can contain glass and shadows.
The element type of this class is "building".
Buildings cannot be created with dynamic object model IDs (like a door that opens when you push it), they are meant to be used for static objects, mainly buildings as the name suggests. For example, object ID 1502 (Gen_doorINT04) is a dynamic object model, which can be spawned using createObject. On the other hand, object ID 3556 (compmedhos3_LAe) is non-dynamic, you can use it with createBuilding.
Buildings can only be created inside regular GTA:SA Map Boundaries (X between -3000 and 3000; Y between -3000 and 3000). Use createObject to spawn objects outside these normal limits.
Created buildings can have LOD models, which is possible using createBuilding to spawn the LOD building, then setLowLODElement to associate it with a non-LOD building element created beforehand. LOD model distance changed with engineSetModelLODDistance affects buildings too.
