I actually finished the Troll from The Witcher game. It was a little project for the videogame class.
He has been made trying to be as exactly as I could with the creature.
I used Zbrush for modeling and texturing, 3ds max, Keyshot for the high poly render and marmoset toolbag for the real time render of the low poly version.
3200 polys for the low poly version, and textures 2048x2048
