Yeh - a quick google shows I’m probably wrong about that. I could have sworn I was using them in UDK but meh, that was many years ago.
The tech and/or idea might have been created by Crytek, but Lionhead/Epic obviously implemented their own version. Doesn’t really matter…
I doubt Epic are going to do much with LPV, especially if they’re not using it internally and with it not being a fully supported feature. Like almost all GI solutions it only really works for limited outdoor scenes anyway. It looked good on Fable Legends but if what has been said in this thread is true (I’ve heard different but meh), then it was only ever designed for that game anyway.
I expect they’ll take pull requests though. Unfortunately it looks like we’re limited to fixing it ourselves for now.
