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   - (Section 0)  - inst
4b - UINT32   - (Section 1)  - 0 (unused)
4b - UINT32   - (Section 2)  - grge
4b - UINT32   - (Section 3)  - cars (only used in *_stream*.wpl)
4b - UINT32   - (Section 4)  - tcyc 
4b - UINT32   - (Section 5)  - 0 (unused)
4b - UINT32   - (Section 6)  - 0 (unused)
4b - UINT32   - (Section 7)  - 0 (unused)
4b - UINT32   - (Section 8)  - mlop (only used in *_strbig*.wpl)
4b - UINT32   - (Section 9)  - lodm (only used in lodcull_*.wpl)
4b - UINT32   - (Section 10) - slow
4b - UINT32   - (Section 11) - 0 (unused)
4b - UINT32   - (Section 12) - 0 (unused)
4b - UINT32   - (Section 13) - 0 (unused)
4b - UINT32   - (Section 14) - 0 (unused)
4b - UINT32   - (Section 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

XPL and CPL

In the XBox 360's version of GTA 4 same files have the extension .xpl, PS3 version have the extension .cpl. 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. .xpl and .cpl files are identical in structure.
