WPL is the format of the map-related files in GTA IV similar to Binary IPLs introduced with GTA SA. It can be edited using WPL Manager.

File Format

Binary Headers

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

Size = 68 bytes
4b - UINT32   - (Version)    - value always "3"
4b - UINT32   - (?????? 0)  - inst
4b - UINT32   - (?????? 1)  - 0 (unused)
4b - UINT32   - (?????? 2)  - grge
4b - UINT32   - (?????? 3)  - cars (only used in *_stream*.wpl)
4b - UINT32   - (?????? 4)  - tcyc 
4b - UINT32   - (?????? 5)  - 0 (unused)
4b - UINT32   - (?????? 6)  - 0 (unused)
4b - UINT32   - (?????? 7)  - 0 (unused)
4b - UINT32   - (?????? 8)  - mlop (only used in *_strbig*.wpl)
4b - UINT32   - (?????? 9)  - lodm (only used in lodcull_*.wpl)
4b - UINT32   - (?????? 10) - slow
4b - UINT32   - (?????? 11) - 0 (unused)
4b - UINT32   - (?????? 12) - 0 (unused)
4b - UINT32   - (?????? 13) - 0 (unused)
4b - UINT32   - (?????? 14) - 0 (unused)
4b - UINT32   - (?????? 15) - blok (section ignore by the game)

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

Size = 48 bytes
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 - Flags
4b - INT32  - LOD Index 
4b - UINT32 - Unknown
4b - FLOAT  - Unknown

Rotation information as Quarternion

Section 2 - GRGE(Garage)

Size = 48 bytes
4b - float   - X1
4b - float   - Y1
4b - float   - Z1
4b - float   - frontX
4b - float   - frontY
4b - float   - X2
4b - float   - Y2
4b - float   - Z2
4b - UINT32  - DoorType
4b - UINT32  - GarageType
8b - char    - GarageName

X1, Y1, Z1 = lower left vertex position

FrontX, FrontY = lower right front vertex position

X2, Y2, Z2 = upper left rear vertex position

Section 3 - CARS

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

Size = 56 bytes
4b - float   - X
4b - float   - Y
4b - float   - Z
4b - float   - Unknown
4b - float   - Rotation
4b - float   - Rotation
4b - UINT32  - Model name hash
4b - int32   - Car color 1
4b - int32   - Car color 2
4b - int32   - Car color 3
4b - int32   - Specular color
4b - UINT32  - Flags
4b - int32   - Alarm
4b - int32   - Unknown


Section 4 - TCYC

Size = 56 bytes
4b - float   - X1
4b - float   - Y1
4b - float   - Z1

4b - UINT32  - Unknown1
4b - UINT32  - Unknown2
4b - UINT32  - Unknown3
4b - UINT32  - Unknown4
4b - UINT32  - Hash

X1, Y1, Z1 = lower left vertex position

X2, Y2, Z2 = upper left rear vertex position

Hash = Box hash name

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.
