Overview

Format used by various resources in the Scenegraph.

Format

DWORD - Version
DWORD - DataType (changes between filetypes)
DWORD - Index3 (unused)
DWORD - Index1
DWORD - Index2

//Internal Chunks: These are the TGIs that identify each chunk
-Repeat Index2 Count Times
QWORD - I64
DWORD - TID
DWORD - GID

//External Resources: These are TGIs of referenced items (e.g. DDS Image)
-Repeat Index1 Count times 
QWORD - I64
DWORD - TID
DWORD - GID

-Repeat Index2 Count times
DWORD - Position of the Chunk (absolute)
DWORD - Size of the Chunk

References

Block references are 1 based(0 reserved for a null reference), with a flag for the type of reference.

Flag Type Description
0x00000000 Public Internal Chunks, with a max index of the 'DataType' field
0x10000000 Private Internal Chunks, indices start after the 'DataType' field
0x20000000 External seems to be unused
0x30000000 Delayed External Resources

PommesTSR note on DataType

  • For most objects DataType is 0x1 but for Rugs (as an example) DataType is 0x2. When DataType is 0x2 the VRTFIndex/VBUFIndex seems to be 1-based instead of 0 for the MLOD-chunks in the MLOD RCOL. Dont know if this is valid for any other index references.

plj note on DataType/Flag

  • Given that "Public" is a reference to an internal chunk before "DataType", doesn't that mean "DataType" is really "Number of Internal Public Chunks"?
  • Also, doesn't "Private" mean "relative to current chunk" rather than "Add on DataType"?

User:Dd764ta note on DataType/Flag

  • Yes I think "DataType" would be more accurately described as number of public chunks
  • Not exactly, private chunks just begin after the public chunks. It appears to be relative because in most files it is only the last public chunk that references private ones. An example of this would be the MODLs in the world packages, where the MLODs are private and their references are clearly not relative but start after the public chunks.

Chunks

The Type ID will also be the first chunk after the header(with the exception GEOM).

Resource Types

These are the possible resource types, they are named by their first chunk.

Type ID Name Description
0x015A1849 GEOM Body Geometry
0x01661233 MODL Object Geometry
0x01D0E75D MATD Material Definition
0x01D10F34 MLOD Animated Texture

used to be Object Geometry LOD, defined by EA as animated texture: const unsigned int kAnimatedTextureResourceID = 30478132;

0x02019972 MTST
0x021D7E8C TREE Speed Tree Data
0x02D5DF13 S_SM Jazz state machibe
0x033260E3 TkMk Track Mask
0x0355E0A6 BOND Slot Adjusts

0x63A33EA7 ANIM Animated Texture
0x736884F1 VPXY Model Links
0xD3044521 RSLT Slot Definition

Model Chunks

Possible chunks embedded in MODL and MLOD resources.
