BGEO (Body Geometry)
Researched by Karybdis

Here's the preliminary structure. Due to apparent invariance in some of the values, they cannot be decoded at the moment.

DWORD - Magic (BGEO)
DWORD - Version (768 or 0x00030000)
DWORD - Section 1 Count (56 bytes each)
DWORD - Section 1 SubEntry count (0x04, invariant?)
DWORD - Section 2 Count (Words)
DWORD - Section 3 Count (6 BYTES)
DWORD - Section 1 Pre-SubEntry size (0x08, invariant?)
DWORD - Section 1 SubEntry entry size (0x0C, invariant?)
DWORD - Section 1 offset (from beginning)
DWORD - Section 2 offset (from beginning)
DWORD - Section 3 offset (from beginning)

-Section 1 56 byte entries
DWORD AgeGender Flags
DWORD FacialRegion/BodyRegion
--Section 1 Subentries
	DWORD Index of Last SubEntry WORD index (0 for first subentry) (Last Face Index?)
	DWORD Index to WORD Entries (Index in Face indexers list?)
	DWORD Index to S3 Entries (Index in Blend Vector list?)

-WORD Entries (Face Indexes?)
	WORD (Face Index?)

-S3 Entries (Blend Vectors?)
	WORD (Vector Vertex1?) (I think this is a 16bit float)
	WORD (Vector Vertex2?) (I think this is a 16bit float)
	WORD (Vector Vertex3?) (I think this is a 16bit float)

Much thanks to Rick for figuring out Section1 parsing structure (Karybdis)
