[2] Bytes - Number of Faces
[1] Byte - Null

Vert Listing

15 Byte rows

[2] Bytes - Global X Position
[2] Bytes - Global Y Position
[4] Bytes - Height {Float}
[4] Bytes - Packed Normal {PackedXYZ}
[1] Byte - 00 or FF (indicates next X or Y value?)
[1] Bytes - TU offset, Actual TU = (TU + (this-127)/127)
[1] Bytes - TU offset, Actual TU = (TU + (this-127)/127)

Faces

2 Bytes
[2] Bytes - Number of Faces

Second Table (Unused Graphics?)

Originally believed to be the mesh, could be used for internal editor only.
[2] Bytes - Placement (X)
[2] Bytes - Placement (Y)
[2] Bytes - Tile Value (X) (Based on Dimension)*
[2] Bytes - Tile Value (Y) (Based on Dimension)*

*If Value is size of Map then this is the lowest LOD

[1] Byte - Indicator (01 - Indicates that it contains Offsets. Else it is only 47 Bytes in Length)
[1] Byte - Indicator (Section Start)
[1] Byte - Indicator (Section End)
[4] Bytes - Offset to Compressed Chunk
[4] Bytes - Size of Entire Table (If Value is present this indicates a start of a new LOD)
[4] Bytes - Offset Push Within Table (Next Section to Read, Table treated as internal file!)
[4] Bytes - World Map Start Position (X) {Float}
[4] Bytes - World Map Start Position (Y) {Float}

Offset Rows

If Indicator = 01 above then loop until starting indicator equals (stop indicator above)
13 Byte Rows

[1] Byte - Indicator (Row start based on LOD)
[4] Bytes - Offset to compressed chunk
[4] Bytes - Compressed Chunk Size
[4] Bytes - Offset to specific compressed Data (Offset to compressed chunk + Value of These Bytes)

*Additional Notes Number of LODs seems dependent on First Table Rows. Example Creature Hub 4 Rows in first Table. Graphics It Contains (4 High Quality, 6 Medium, 1 Low)

*Each Compressed Package is LZO Compressed following this format:
[4] Bytes - Decompressed Size
[4] Bytes - Compressed Size

Decompressed Data

[2] Bytes - Image Dimension (X) it takes up on Map *
[2] Bytes - Image Dimension (Y it takes up on Map *

*If Dimension equals map dimensions then it is the lowest LOD

[2] Bytes - Tile Placement of Image (Based on Map Dimensions) (X)
[2] Bytes - Tile Placement of Image (Based on Map Dimensions) (Y)
[1] Byte - Null
[1] Byte - Indicator for LOD (not an actual value!)
[3] Bytes - Unkown Based on LOD
[1] Byte - Indicator new section start
[1] Byte - Image Dimensions (X) (Actual Image Size, for editing)
[1] Byte - Image Dimensions (Y) (Actual Image Size, for editing)
[1] Byte - Indicator new section start
[2] Bytes - Image Dimensions Repeat (X) as 2 bytes
[2] Bytes - Image Dimensions Repeat (Y) as 2 bytes
[1] Byte - Indicator new section start
[4] Bytes - Unknown
[6] Bytes - Null?
[4] Bytes - Always (01 00 00 00) Indicates Image Start
~ DXT1 Image (To get Image size take actual dimension ( X * Y / 2)

*The Rest of file is currently Unknown

Third Section (Flora/Model)

The only offset to this section exists in Static Map Header see: [4] Bytes - Offset in Third Section table (Third Section Offset + these bytes)

*The following entries are very sloppy and jump around quite a bit.

[4] Bytes - always zero?
[4] Bytes - if zero again it will need to read until it is at least reaches 1.
[4] Bytes - Global X coords [Float]
[4] Bytes - Global Y coords [Float]
[4] Bytes - Global Z coords [Float]
[4] Bytes - Unknown (Rotation?) [Float]
[4] Bytes - Unknown (Always 23?) [Float]
[4] Bytes - Unknown [Integer]
[4] Bytes - Offset to Chunk [Integer]
[4] Bytes - Chunk Size [Integer]
[4] Bytes - Offset in Chunk (take above Offset + This) [Integer]
[2] Bytes - Placement X? [Short]
[2] Bytes - Placement Y? [Short]
[2] Bytes - Size X? [Short]
[2] Bytes - Size Y? [Short]
[1] Byte - Indicates more entries. If zero reading is finished.

Here is the Tricky Part. If Offset above leads directly to anything other than zero you read below, else the entry is dead and the loop above is redone.

[4] Bytes - Number of Sections (Array) [Integer]
[4] Bytes - Chunk Offset [Integer]
[4] Bytes - Chunk Size [Integer]
[4] Bytes - Package Offset (Chunk Offset + Package Offset) (This will lead to compressed data) [Integer]
[4] Bytes - Global X coords [Float]
[4] Bytes - Global Y coords [Float]
[4] Bytes - Global Z coords [Float]
[4] Bytes - Unknown (Rotation?) [Float]
[4] Bytes - Unknown [Float]
[4] Bytes - Unknown [Integer]
[4] Bytes - Unknown [Integer]

Compressed Package
