A free mod for Witcher 3, by vervurax.
The ModKitchen toolkit for The Witcher 3 is an application for your PC that allows you to edit and customize the game. It can be used on any version of the game, and it can edit and build mods, as well as make maps, add NPCs, weapons, and armor. It can also import a list of files from a mod or map, and it will create a new instance for every file.
The goal is to have one GUI to help you deal with the game files for your mod, without the need to type stuff into the command line. It is an application that uses the official ModKit toolkit.
