Yesterday, CD Projekt RED released some modding tools for The Witcher 3: Wild Hunt. Via the game’s Modkit, players can change models, scripts and/or textures. However, you are out of luck if you were hoping for a full REDkit Editor.
As Marcin Momot confirmed, there won’t be – at the moment – any REDkit Editor for The Witcher 3.
@MeerMusik This is the mod support for the Wild Hunt. At this moment we are not planning to release anything else.

And that is that.
