WPL is the format of the map-related files similar to IPLs from the previous games. It can be edited with WPL Manager.

File Format

Each world placement file starts with one single header followed by the object placement information. The structure for the header is very simple:

4b - UINT32   - Unknown
4b - UINT32   - Instances

The placement information corresponds to the previous instance section of the .ipl files. They have a binary structure like the binary ipl files introduced with San Andreas:

Section 0 - INST

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 - UINT32  - Model name hash
4b - UINT32  - Unknown
4b - UINT32  - LOD Index (Index of another model in the current file)(Line entry number of LOD model)
4b - UINT32  - Unknown
4b - UINT32  - Unknown

Rotation information as Quarternion

Section 2 - Garages

4b -  FLOAT   - Position X1
4b -  FLOAT   - Position Y1
4b -  FLOAT   - Position Z1
4b -  FLOAT   - Position X2
4b -  FLOAT   - Position Y2
4b -  FLOAT   - Position X3
4b -  FLOAT   - Position Y3
4b -  FLOAT   - Position Z3
4b -  UINT32  - DoorType
4b -  UINT32  - GarageType
4b -  UINT32  - hash
4b -  UINT32  - Unknown

X1, Y1, Z1 = lower left vertex position, X2, Y3, Z3 = upper right vertex position, X3, Y2 = lower left vertex position for Garage entrance

Section 3 - Parked Cars

only used in the (*_stream*.wpl) files

4b - FLOAT  - Position X
4b - FLOAT  - Position Y
4b - FLOAT  - Position Z
4b - FLOAT  - Unknown
4b - FLOAT  - Unknown
4b - FLOAT  - Unknown
4b - UINT32 - Model name hash
4b - INT32  - Unknown
4b - INT32  - Unknown
4b - INT32  - Unknown
4b - INT32  - Unknown
4b - INT32  - Unknown
4b - INT32  - Unknown
4b - INT32  - Unknown

Section 4 - CULL

these are used for interiors directly accessed from outdoor locations.

4b -  FLOAT  - Position X1
4b -  FLOAT  - Position Y1
4b -  FLOAT  - Position Z1
4b -  FLOAT  - Position X2
4b -  FLOAT  - Position Y2
4b -  FLOAT  - Position Z2
4b -  INT32  - Unknown
4b -  INT32  - Unknown
4b -  INT32  - Unknown
4b -  INT32  - Unknown
4b -  UINT32 - Model name hash

X1, Y1, Z1 = lower left vertex position, X2, Y2, Z2 = upper right vertex position

Section 9 - LODcull

only used in lodcull_x.wpl files, usually located in 'Rockstar Games\Grand Theft Auto IV\pc\data\maps\generic' folder

4b -  FLOAT  - Position X1
4b -  FLOAT  - Position Y1
4b -  FLOAT  - Position Z1
4b -  FLOAT  - Position X2
4b -  FLOAT  - Position Y2
4b -  FLOAT  - Position Z2
4b  - UINT32 - unknown UINT32
4b  - UINT32 - Hash 1
4b  - UINT32 - Hash 2
4b  - UINT32 - Hash 3
4b  - UINT32 - Hash 4
4b  - UINT32 - Hash 5
4b  - UINT32 - Hash 6
4b  - UINT32 - Hash 7
4b  - UINT32 - Hash 8
4b  - UINT32 - Hash 9
4b  - UINT32 - Hash 10
32b - String - Model name 1
32b - String - Model name 2
32b - String - Model name 3
32b - String - Model name 4
32b - String - Model name 5
32b - String - Model name 6
32b - String - Model name 7
32b - String - Model name 8
32b - String - Model name 9
32b - String - Model name 10

X1, Y1, Z1 = lower left vertex position, X2, Y2, Z2 = upper right vertex position

Section 10 - Unknown Zon or Cull

4b - FLOAT - Position X1
4b - FLOAT - Position Y1
4b - FLOAT - Position Z1
4b - FLOAT - Position X2
4b - FLOAT - Position Y2
4b - FLOAT - Position Z2

X1, Y1, Z1 = lower left vertex position and X2, Y2, Z2 = upper right vertex position


XPL

In the XBox 360's version of GTA 4 same files have the extension .xpl. The XPL and WPL formats are same, but due to the fact XPL files are used on the Xenon platform its data is stored in the big-endian order.
