So is this where ZBrush and Hexagon differ? ZBrush can add geometry and Hexagon can't? I am just trying to understand the difference between the two applications and decide which one is going to be better to learn? 1) For example. If I have created a head in Hexagon, and I have added details to it like wrinkles, veins etc. if I decide that I want to add a horn to the model am I hooped or is it possible? I think it is possible in ZBrush, I am just wondering if it is in Hexagon? 2) But are you saying the horn can't be painted on but must be modeled?
