Online, the 35-year-old German man calls himself Smaz. He, too, does not wish to be identified by his real name, though he says all of his friends and family know what he does.

Smaz makes patches for PC games that remove the clothing from female characters or replace the clothing textures with flesh and genitals. He started in 2004 and says he's made more than 20 nude patches for games like Neverwinter Nights 2, Oblivion, FlatOut and The Sims 2. His patch for Fable makes the breasts of female NPCs visible. In his patch for Jade Empire, you can see female avatars' vaginas up their skirts. He also added detailed genitals to the characters of Battle Raper, a Japanese 3-D fighter where the female combatants' clothes fall off when struck.
