GTA III format
ID, ModelName, PosX, PosY, PosZ, ScaleX, ScaleY, ScaleZ, RotX, RotY, RotZ, RotW
| Identifier | Description |
|---|---|
| A number which is used to identify the object as defined in the IDE file inside the map system. | |
The name of the model inside an image file which is defined in the gta.dat file without extension (.dff)
| |
| The position of the object in the world as floating point values. Note: the decimal seperator must be ".", not ",". | |
| 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 ",". | |
| 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 |

The name of the model inside an image file which is defined in the gta.dat file without extension (.dff)
| |
| 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. | |
| The position of the object in the world as floating point values. | |
| 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. | |

GTA SA format
ID, ModelName, Interior, PosX, PosY, PosZ, RotX, RotY, RotZ, RotW, LOD

| A number which is used to identify the object as defined in the IDE inside the map system. | |
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.
| |
| A number defining the interior (render-level) the object is located in. | |
| The position of the object in the world as floating point values. | |
| The rotation of the object as quarternion. Note: the decimal seperator must be ".", not ",". | |
| 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] |

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 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 |
