These files are used for all of World of Warcraft's water. For each contained body of water in the game (except for the oceans) there exists one of these files. There is also a WLQ file located at the exact same file and pathname as the .wlw files. Little else is known about this file format...
Type Name Description char Identifier "*QIL" int16 Used 1 if data is in the file. int32 Version always 01000400 int16 Unknown always 0 int32 nCount how many liquids are in this chunk int32? Unknown ?
- nCount blocks of 0x168 bytes.
Type Name Description float heights a height map for this section of the water uint16? unk ?
The first 0xC0 bytes are made of 48 float's that make up 16 vertices ( z-up ) arranged in a grid that starts in the lower right corner.
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
When all the chunks are combined, they form a height map of the water, similar to those in the ADT's
The rest of the block seems to be made of 2 floats ( always integers ) and 40 uint32's.
