OME

OME is a model format used in Yakuza, Yakuza 2, and by extension, Ryu Ga Gotoku 1 + 2 HD Edition. It was phased out and replaced with GMD.

Format Overview

A typical OME file has the following order:

1) File header data

2) Object/physics data*

3) ODBP/MDBP block

MDBP is an earlier version of OME and is not supported by the game, attempting to load one may lead to a crash.

Within ODBP: 1) File header data

2) Mesh block (pointers, material ids etc.)

3) Armature block

4) File header data

5) Material group**

6) Mesh data (vertex info and face index table)

7) End block

*Unclear yet if this actually does contain physics, there seems to be coordinates for a collision shape in prop/stage object OME files.

**Doesn't seem to control anything related to actual materials, here like materials are grouped together.
