What kind of sick video cards do you have? I keep reading complaints about how the video memory is not enough. Sure it is, ever tried Lumion? I have 6 GB and I want a simple answer to the question raised in the first place (only UE 4 staff answers): Is there a method to stop using 100% CPU to build/compile lighting and use more GPU? I once read you can do a sript for that but I forgot where. PLEASE ANSWER THE QUESTION.
