Using Destructors
Destructors are areas that, when a a generated asset enters it, that asset is removed from the scene. A destructor will only destroy elements created at run time by a generator.
The main purpose of a destructor is to prevent scenes from becoming overcrowded with assets which can speed up your simulation, they can also be useful if there isn't a lot of space in your model.
A typical use for a generator/destructor pair is to create a steady stream of cars or pedestrians moving past a fixed point in which case both generator and destructor are placed off camera with the area of interest in the field of view.
Unlike generators which can generate only one asset type, destructors will work on any asset type.
