This software is a toolkit used to unpack and extract 3D models from several games :

• The Witcher 1 (Unpacker, 3D model and animation loader)
• The Witcher 2 (Unpacker, 3D model loader)
• The Witcher 3 (Unpacker, 3D model loader)
• Redkit (3D model importer/exporter)
• The Council (Unpacker, 3D models/scenes loader)

To get started with the software, take a look at the wiki

To report problems in the software, please be as complete as possible in the reports to facilitate help and correction of issues.

In particular, the following information may be useful:

• The exact file name and the game you have a problem with
• Logs (Go to Settings/Debug/Enable debug.log, restart the software, reproduce you issue and give me the generated log file)
• The content of your config.xml file

By the way if you're a dev and want to contribute, it would obviously be appreciated :) (see the wiki to compile the software)
