KrxImpExp

KrxImpExp (Kerrax Import Export) is an open-source Blender add-on that adds support for importing and exporting 3D model formats used by the ZenGin engine in Gothic I and Gothic II.

The original KrxImpExp was created by Kerrax for older 3D editors. The current version, maintained by Patrix9999 and supported by the Gothic Modding Community, has been ported to the modern Blender API (2.80+) and works on Windows, Linux, and macOS.

tip

KrxImpExp is the go-to tool for anyone who wants to create or modify 3D models, worlds, or animations for Gothic.
