Cull is one of the major IPL sections used in plaintext map placement files. It is used to create zones with different behaviour like mirrors or fixed camera positions just as it is able to influence the environment. For example it is able to disable rain in certain areas.
GTA III / Vice City
Cull zones in the first 2 parts of the GTA 3D series are built by a box which is controlled by various flags.
