CGFX

CGFX is a container format used to store graphics resources. It can contain 3D models, textures and animation data.

DICT

DICTs are generic structures used to store values (and associate them to a key ?). A DICT header is 0x1C bytes long.

DICT header :

Offset	Length	Description
0x0	0x4	Magic "DICT"
0x8	0x4	DICT size (in bytes)
0xC	0x4	Number of entries

DICT entry:

Offset	Length	Description
0x0	0x4	?
0x4	0x4	?
0x8	0x4	Value (often offsets)
0xC	0x4	?

CMDL Header

Offset	Length	Description
0x0	0x4	Magic "CMDL"
0x8	0x4	CMDL section size (in bytes)
0x28	0x4	Offset (self-relative) to first DICT
0x2C	0xC	Global scale vector (3 floats : x, y, z)
0xB0	0x4	N/2, where N is the number of entries in SOBJ list
0xB4	0x4	Offset (self-relative) to SOBJ list
0xB4+[0xB4]	0x4*N*2	SOBJ list; each word is an offset (self-relative) to an SOBJ structure

CMDL is used to describe a 3D model. A CMDL section refers to outside data; it can not be considered separately from the rest of the CGFX file. The second DICT in the CMDL section contains offsets to MTOB objects.

SOBJ

SOBJ structures can be used to describe 3D objects that are part of the model. If such is the case then they will follow this structure :

Offset	Length	Description
0x0	0x4	Magic "SOBJ"
0x44	0x4	X = Offset (relative to SOBJ magic) to SOBJ data structure
X+0x18	0x1	Face data format (?) : 0x1 = u8, 0x3 = u16
X+0x20	0x4	Face data section size (in bytes)
X+0x24	0x4	Face data section offset (self-relative)
X+0x58	0x4	Vertex data section size (in bytes)
X+0x5C	0x4	Vertex data section offset (self-relative)
X+0x68	0x1	Vertex data format size (in bytes)

Vertex format size	Description
0x14	X (float), Y (float), Z (float), U (float), V (float)
0x18	X (float), Y (float), Z (float), Unk (u32?), U (float), V (float)
0x20	X (float), Y (float), Z (float), NX (float), NY (float), NZ (float), U (float), V (float)
0x28	X (float), Y (float), Z (float), NX (float), NY (float), NZ (float), U (float), V (float), Unk1 (u32?), Unk2 (u32?)
