I just stumbled upon this commit that says the diffuse model has been reverted back to Lamber. I think originally it was Burley, the thing that Disney used for some movies? https://github.com/EpicGames/UnrealEngine/commit/b7fd46177d61dab69af871665b8d78af5e1619fc
Is this just for performance reasons and what kind of implications will this have on art and overall looks?
