There are no official mods for the "Witcher 3: The Wild Hunt" yet, but this little mod will at least give you an idea of what to expect. It will make the world a little darker, a little more mysterious, and it will definitely add an interesting dimension to the game.

What does it do?

It will change the eye textures of various characters to normal human eyes. This means that if you were watching a character, you will no longer see the sparkles in their eyes.

This is a very simple mod and it is not very intrusive.
