How does this concept phase tie in with the 3D modeling phase?

Normally at the very end, when we have a concept that we like and we get it approved, we pass that image over to the modelers, the character artists, and then they'll build, they'll realize the concept into the game. So they'll sculpt it out first in ZBrush, do a detailed sculpt as much as they can. But during that time the character artists will talk with our tech artists to make sure that it fits the volumes, fits the zones, that it also will be possible for that thing to function in the game.
