Contents

Format

GTA III format

ID, ModelName, PosX, PosY, PosZ, ScaleX, ScaleY, ScaleZ, RotX, RotY, RotZ, RotW
Identifier Description
ID
A number which is used to identify the object as defined in the IDE file inside the map system.
ModelName
The name of the model inside an image file which is defined in the gta.dat file without extension (.dff)
PosX, PosY, PosZ
The position of the object in the world as floating point values.
Note: the decimal seperator must be ".", not ",".
ScaleX, ScaleY, ScaleZ
The scaling of the object as floating point values. By default each value is 1.0, which means the object is not scaled at all.
Note: the decimal seperator must be ".", not ",".
RotX, RotY, RotZ, RotW
The rotation of the object as quarternion.
Note: the decimal seperator must be ".", not ",".

GTA VC format

ID, ModelName, Interior, PosX, PosY, PosZ, ScaleX, ScaleY, ScaleZ, RotX, RotY, RotZ, RotW
Identifier Description
ID
A number which is used to identify the object as defined in the IDE inside the map system.
ModelName
The name of the model inside an image file which is defined in the gta.dat file without extension (.dff)
Interior
A number defining the interior (render-level) the object is located in. It is an optional parameter; by default the object's interior is 0.
PosX, PosY, PosZ
The position of the object in the world as floating point values.
ScaleX, ScaleY, ScaleZ
The scaling of the object as floating point values. By default each value is 1.0, which means the object is not scaled at all.
RotX, RotY, RotZ, RotW
The rotation of the object as quarternion.

GTA SA format

ID, ModelName, Interior, PosX, PosY, PosZ, RotX, RotY, RotZ, RotW, LOD
Identifier Description
ID
A number which is used to identify the object as defined in the IDE inside the map system.
ModelName
The name of the model inside an image file which is defined in the gta.dat file without extension (.dff). The parameter doesn't seem to function in the game. Any name used will not affect the rendering of the model.
Interior
A number defining the interior (render-level) the object is located in.
PosX, PosY, PosZ
The position of the object in the world as floating point values.
RotX, RotY, RotZ, RotW
The rotation of the object as quarternion.
Note: the decimal seperator must be ".", not ",".
LOD
The number of the LOD which is located inside the same instance block as the current model.
By default this is -1 which means no LOD is defined.[1]

Binary Format

INST is also one of the known sections which can be used in binary format inside streaming files. It's format is similar to the plain text format:

4b  - FLOAT    - Position X
4b  - FLOAT    - Position Y
4b  - FLOAT    - Position Z
4b  - FLOAT    - Rotation X
4b  - FLOAT    - Rotation Y
4b  - FLOAT    - Rotation Z
4b  - FLOAT    - Rotation W
4b  - INT32    - Object ID (as an index to the IDE)
4b  - INT32    - Interior
4b  - INT32    - LOD index

GTA IV format

Limitations

Each game has different limitations. The most important limit for the instance section is the so-called map boundary, which is a notional boundary around the map. Outside those borders no objects will be visible. If an object is intersecting the bounds it may be displayed incorrectly.

Game Mapping Boundary
San Andreas
San Andreas has a square (or cube) as the major limit. Its dimension is 3000.0 units away from the origin point.
This limit can be increased using the SA Limit Adjuster by Sacky
