Introduction

This document describes the structure of the POB file format used by the GRE (Ghost Recon engine). GR (Ghost Recon) game POB files are stored in the "Model" folder and has an extension of ".pob".

Overview

The POB file contains the information about static, dynamic (animated) and moving in-game 3D objects: vehicles, aviation, military equipment, effect particles. For example, tanks or helicopters, guns, boats and explosion effects are stored in this type of game files. It includes information about materials, textures, 3d geometry, object's animations and additional data for a game engine, such as object tagging. The POB file can store only one tagged in-game object, e.g. one tank or one machinegun. You can create the POB files with an official developer plugin for 3DS MAX 3-5 version.

Overall file structure

The POB file format is divided into four major sections and three signatures between theme as shown in the POB file structure.

Table 1. POB file structure

№	Section	Description	Links
1	File Header Section	File header	see Table 2
2	BeginModel Signature	-
3	1. MaterialList Section	Materials and textures information	see Table 3
4	2. GeometryList Section	Geometry objects data	see Table 13
5	EndModel Signature	-
6	3. ObjectList Section	Objects (nodes) hierarchy	see Table 39
7	EndPOB signature	-

Notes

The file header has a fixed length; the other three sections are variable in length.

Sections

File Header Section

Section overview

The fist file section contains the basic file properties. The POB header is 21 bytes long.

Table 2. File header structure

№	Length	Type	Description	Value
1	4	integer	File signature length. Equal to 9.	9
2	9	string	File signature: always equal to 'BeginPOB.'.	"BeginPOB."
3	4	datetime	File creation date.	variable
4	4	datetime	File modified date.	variable

Notes

The file signature is unique file identifier helps game engine to auto-detect the file type on load. Most of GR game files have there unique signatures.

BeginModel Signature

BeginModel signature is 15 bytes long. Main file sections start right after this signature.
