Sure, the Star Wars: The Old Republic trailer from E3 may have been lacking in the gameplay department, but that didn't stop it absolutely rocking the socks off anyone that saw it. The people that made that possible are from Blur Studio, specialists in CG animation for games, films, and commercials. The IGN video above features an interview with Derron Ross, an animation supervisor for the company. He explains that although you might not realize it in the final products, a ton of the highest quality game videos are from Blur -- as an example, one of the early Warhammer Online trailers that a lot of you will have seen is from them. Ross goes on to describe what it takes to create something with such dangerously high levels of awesomeness.
If this little behind-the-scenes look at the SWTOR trailer has you craving more CG goodness, Blur's website has links to a ton of their other works for your viewing pleasure.
