CULL is a section in the IPL file. It is used to create zones with different behaviour like mirrors [1] or fixed camera positions. It can also influence the environment like disable rain within the zone and certain police behaviors.

GTA III / Vice City
Cull zones in GTA III and Vice City are built by a box which is controlled by various flags[2]. By default, most of the cull zones are located in data\maps\cull.ipl for both games.
CenterX, CenterY, CenterZ, LowerLeftX, LowerLeftY, LowerLeftZ, UpperRightX, UpperRightY, UpperRightZ, Flags, Unknown
| Identifier | Description |
|---|---|
| A point which defines the center of the box in real world coordinates Useless? Doesn't seem to affect the zone. | |
| A point which corresponds to the lower left corner of the box. | |
| A point which corresponds to the upper right corner of the box. | |
| The behaviour of the cull zone – see below. | |
| Always 0 |
The first three parameters are odd since placing any values do not have an effect on the zone. They seem to act like identifiers rather than functions.
Flags
Flags are numbers which are build out of a collection of numbers formed by the power of 2-numbers lower than 230. Some are defining various behaviours of the zone. They can be combined by simply adding one flag value to another (see binary to decimal conversion).
| Flag | Binary | Description |
|---|---|---|
| Enables all flags. | ||
| Camera close in into player using closest third-person view camera mode, does not close in if in first person or cinematic mode, camera mode cannot be changed while in the zone | ||
| camera remotely placed outside the zone, no control of camera, camera mode cannot be changed while in the zone | ||
| Lowers the camera angle on boats | ||
| Rain-free, police helicopter-free zone | ||
| Police will not exit their vehicles voluntarily. They will only exit if you do something to them (like shoot it). Cops both on foot and in vehicles will not chase you but can shoot at you. | ||
| Police will always exit their vehicles once they are spawned ONLY IF you have a wanted level. If you don't, they'll drive normally. | ||
| Some visual water effects are removed like the transparent waves and sparkles on the water (like the water in GTA III). |

San Andreas
San Andreas has two different major formats in the game:
CenterX, CenterY, CenterZ, Unknown1, Width, Bottom, Length, Unknown2, Top, Flag, Unknown3
CenterX, CenterY, CenterZ, Unknown1, Width, Bottom, Length, Unknown2, Top, Flag, Vx, Vy, Vz, Cm
Coordinates are always rounded to the nearest world unit so that they are no longer floating point values, they are non-decimal integers.
| Value | Description |
|---|---|
| Vector to the center of the cull zone. | |
| Allways 0. (The third value appears to be an placeholder. If it is zero the parser stops here. If it is not zero the parser tries to parse mirror information) | |
| Dimensions of the zone along x-axis. | |
| Dimensions of the zone along y-axis. | |
| Distance from the center to the top/bottom of the zone. The sum of both values represents the zone's height. | |
| Flags - see below! | |
| Mirror parameters [4]. |

Flags
Not all flags from the previous game are compatible with San Andreas.
| Flag | Binary | Description |

| Enables all flags. | ||

| camera remotely placed outside the zone, no control of camera, camera mode cannot be changed while in the zone | ||
| Unknown | ||
| Rain-free, police helicopter-free zone | ||
