What is WolvenKit?

An open-source modding tool for The Witcher 3: Wild Hunt and Cyberpunk 2077

Main purpose

This repository was created to demonstrate how CDPR's proprietary REDEngine reads and writes its different file formats, and to experiment the inner works of games running on this engine i.e. The Witcher 3: The Wild Hunt and Cyberpunk 2077. This toolkit is being made solely for research and educational purposes, and the dev team is in no way responsible for any malfunctions that occur from its use. WolvenKit is completely open source, licensed under GPL v3.0, and in no way is it made to generate revenue. An ancestor to this tool was W3Edit, initially developed by Sarcen in 2015, around the time The Witcher 3: Wild Hunt was released. After Sarcen stopped working on W3Edit, it was picked up and continued by the team that is now the WolvenKit Team.

Currently, WolvenKit allows reading and writing nearly every REDEngine file format to some extent. It can also be used to create and edit modifications for the game, using existing and new assets. This feature is actively being worked on, so be sure to check for updates regularly. Our primary focus at the moment is progressing with support for Cyberpunk 2077, CDPR's newest title, running on REDEngine.
