World Of Tanks: Blitz SCPG model format

Reverse engineered information about the model format used by WOTB.

Preface

This resource aims to shed light on the model format, "SCPG", used by WOTB and eventually provide tools to modify and create said models.

Models in WOTB are located in /packs/3d/ and each model comes in a pair of files with extensions .scg and .sc2, for example: packs/3d/Tanks/German/Maus.scg packs/3d/Tanks/German/Maus.sc2. Game files are compressed using the dvpl format, you can use this tool to decompress them.

Current work is based on SC2 version 41 and SCG version 1.
