Understanding how encryption works is key to understanding why it’s so difficult to reverse. Modders are provided with their own unique encryption tool (e.g., kn5enc_….exe or kn5enc_…_acdchecksum.exe ). The process is simple:

This will automatically create a folder containing the .fbx model and associated textures.
