A free mod for Witcher 3, by ScoutBr0.
This mod was created by ScoutBr0, and it's based on the E3 demo. With this mod, the game will look a lot more like the one in the demo. The main difference is the scabbard, which is the part of the sword that is attached to the hilt. In the demo, it is seen as a part of the hilt, but in the actual game, it is separate from the hilt and can be moved around.
This mod is based on the in-game assets and does not require any additional files. The main reason why this is possible is that the assets are stored in the game itself and are not in external storage.
