An interior is an area in the game that is not rendered as part of the "outside world". In GTA III, this is handled by the cullzone.dat file and is mainly used by road and subway tunnels. In Vice City, San Andreas, LCS, and VCS, objects in an interior are assigned a render level through the IPL file. In Vice City, the render level can only be changed through the script file. In San Andreas, it can additionally be changed through the IPL file. By default, the outside world has the render level "0", which doesn't act as an interior.

Interior 13 is a special interior that is reserved for pickups. Placing objects in that interior makes them stream regardless of the interior the player is in.


In the INST section in Vice City and San Andreas, the third column denotes the render level ("interior number") of the object. Objects can only be viewed within a level; objects on other levels will not load and cannot be viewed.

For San Andreas only, you can create an access points to interiors using the ENEX section of the IPL file.

List of areas

This is a list of interior numbers and their corresponding areas used in the games.

Vice City

Not all interiors behave the same way and most of the behaviors are hardcoded. Most interiors disable environmental ambient noise in order to play ambient music, which also disables in-car radio stations. Some disable ambient vehicle noise, which includes engine, door, and tire noises. Most interiors remove visible ocean water.
