Fans of The Witcher 3: Wild Hunt have repeatedly noted that Geralt's eyes in the game are only nominally cat-like. An enthusiast with the nickname TenebrisMods corrected this oversight, thanks to which the witcher's pupils can narrow and dilate depending on the light.
According to the modder, he really missed this detail in the game, which was described in the books. To create the addon, he even conducted a study, studying how exactly the human pupil dilates. The result was the Glowing Modular Eyes with Round Pupils and Netflix Black Eyes mod — with its help, Geralt's eyes will change the width of the pupil depending on the lighting. In addition, the addon changes the eyes of all the witchers in the game.
As the author himself writes, to activate it, you need to go into a dark room or start a fight in the dark. And the «Cat» potion will make the eyes completely black, like in the Netflix series The Witcher.
You can download Glowing Modular Eyes with Round Pupils and Netflix Black Eyes from this link. For it to work, you definitely need the Modular Eyes addon, which is the basis for the mod.
Earlier, another secret was found in The Witcher 3 that fans of the game did not know about. The game recently received three more fan DLCs with new stories, monsters, and armor.
