http://www.illuminatelabs.com/products/beast Lightmass and Beast are two separate things, Lightmass is our solution, Beast is an integrated partner, similar to speed tree, scaleform, and others (link). go to town guys!!
Combining a few different work in progress sculpts to make this character - the face is loosely based on a Battle Beast sketch by Ryan Ottley. LATEST UPDATE:
Mirror's Edge look slightly different because it's lighting was built with Beast, not with Unreal Lightmass. Although was Mass Effect with Lightmass or Beast? Maybe it's just the exaggeration of color bleeding in Mirror's Edge and Beast that made it look that different.
