Unreal is being used very heavily to drive large LED screen backgrounds to film against, often with a roof of LED as well. Placing fixtures in the model that then can be controlled by DMX gives the ability to adjust the way the lighting falls on the subject within the space, allowing you to very accurately light a subject and making it look really real. This enables the DOP to composite the shot in camera, needing little post work to get it looking spot on, where as before, if they'd green screened the shot, everything had to be comp'd in afterwards in post. We've been working hard to get a deliverable solution alongside a team of creatives - that give some images of the smaller setup we delivered in November. Last week we delivered a shoot with a 19m x 4m wall, spine of LED roof and moveable LED walls for a major car manufacturer.
