XSIZETools

XSIZETools is an addon for Autodesk Softimage. It adds support to export & import ZeroEngine (Star Wars: Battlefront I & II) .msh model/animation files.

This addon allows importing and exporting geometry, materials and animations from and to ZeroEngine formats (.msh). Extends base Softimage objects (objects, materials) with ZeroEngine-specific properties to enable advanced features in-game.

A notable part of the work going into this addon was figuring out the exact details of the proprietary binary file format(s) that ZeroEngine consumes (.msh) as there was no official documentation. This repository is the result of that work.
