"Previous to joining Epic, I was working on PlayStation 2 games," Wells tells us. "To create a character would be around about six days, modelling characters of around 1500 to 2000 polygons, unwrapping it and skinning it."
And now? "Well, ideally, what we try to go for is two to three weeks for modelling the high poly, about a week for processing, and about one to two weeks for materials creation. Sometimes, depending on if it's a hero character, that can take about forty-five days including the concept part of it - because of the density of the meshes that we work with."
"To get the detail that we need, our characters are upwards of 30 million polygons."
Each character takes six weeks to create. There's very little room for mistakes, when going back to the drawing board can take months.
From six days to six weeks; from 2000 polygons to 30 million polygons. "It's a big difference," grins Wells, possibly winning our award for best understatement of the week - and even then, the basic figures only scratch the surface of the change that has occurred in game art in the last few years.
