This site contains information about the alphafiles

For information added on 2012-03-24 : files I looked at come from build 3368 (Mjolln√†).

WDT

In the Alpha the ADTs and the WDT were just one big file with this structure :

MVER

See the new files.

MPHD

struct MphdInfo
{
/*0x00*/ int32 unknown1;   // Something related to M2 number.
/*0x04*/ MDNM* mdnm;
/*0x08*/ int32 unknown2;   // Something related to Wmo number.
/*0x0C*/ MONM* monm;
/*0x10*/ int32 unused[28]; // only zeroes
}

MAIN

struct SMAreaInfo
{
 struct SMAreaInfoEntry
 {
  MHDR* mhdr;        // absolute offset
  MCNK* firstMcnk;   // offset relative to MHDR start (so value can also be read as : all ADT chunks total size from MHDR to first MCNK)
  int32 unknown1;    // unused ?
  int32 unknown2;    // unused ?
 } entries[64*64];
};

MDNM

Filenames Doodads.

MONM

Filenames WMOS.

MODF (optional)

See the new files. Unique and at the end of the file for WMO based maps, which contain no ADT parts. First entry looks like a dummy one (2nd int32 is all 0xff, rest of entry is full of 0x0). Total 2 entries counting the dummy one.

RazorfenDowns is "hybrid", it contains both WDT-part optional MODF with the dummy entry, and a MODF for each of its ADTs.

MHDR

struct MhdrInfo
{
/*0x00*/ MCIN* mcin;
/*0x04*/ MTEX* mtex;
/*0x08*/ int32 MtexSize;   // includes chunk name and size
/*0x0C*/ MDDF* mddf;
/*0x10*/ int32 unknown1;   // always 0 ?
/*0x14*/ MODF* modf;
/*0x18*/ int32 unused[10]; // seem unused
}

MCIN

256 Entries, so a 16*16 Chunkmap. See the new files.

MTEX

See the new files.

MDDF

See the new files.

MODF (in ADT part)

See the new files.

MCNK

The header is 128 bytes like later versions, but information inside is placed slightly differently. Offsets are relative to the end of MCNK header.

struct SMChunk
{
/*0x00*/ int32 flags;
/*0x04*/ int32 IndexX;
/*0x08*/ int32 IndexY;
/*0x0C*/ float unknown3;
/*0x10*/ int32 nLayers;
/*0x14*/ int32 nDoodadRefs;
/*0x18*/ MCVT* mcvt;      // (= 0x00)
/*0x1C*/ MCNR* mcnr;
/*0x20*/ MCLY* mcly;
/*0x24*/ MCRF* mcrf;
/*0x28*/ MCAL* mcal;
/*0x2C*/ int32 McalSize;
/*0x30*/ MCSH* mcsh;
/*0x34*/ int32 McshSize;
/*0x38*/       // unknown
/*0x3C*/ int32 nMapObjRefs;
/*0x40*/ int32 holes;
/*0x44*/ UINT2[8][8] ReallyLowQualityTexturingMap;
/*0x48*/
/*0x4C*/
/*0x50*/
/*0x54*/       // unknown
/*0x58*/       // unknown
/*0x5C*/ int32 McnkSize; // (minus header size)
/*0x60*/       // unknown
/*0x64*/ MCLQ* mclq;     // If (value == MCNK size) it means there's no MCLQ.
/*0x68 to 0x80*/         // unused ?
}

FLAG_IMPASS seems to be at the same place as later versions, other flags not verified.

(MCVT) sub-chunk

No chunk name and no size.

It's composed of the usual 145 floats, but their order is different : alpha vertices are not interleaved... Which means there are all outer vertices first (all 81), then all inner vertices (all 64) in MCVT (and not 9-8-9-8 etc.). Unlike 3.x format, MCVT have absolute height values (no height relative to MCNK header 0x70).

(MCNR) sub-chunk

No chunk name and no size.

Same as 3.x format, except values order which is like alpha MCVT : all outer values first, then all inner ones.

MCLY sub-chunk

See the new files.

MCRF sub-chunk

Since there are no MMDX/MWMO MMID/MWID in alpha ADT, MCRF entries directly point to index in MDNM and MONM chunks.

(MCSH) sub-chunk

No chunk name and no size.

See the new files.

(MCAL) sub-chunk

No chunk name and no size.

See the new files.

(MCLQ) sub-chunk

No chunk name and no size.

See the new files.

WMO

See also WMO/v14 page for more detailed information.
