I didn't notice it in Oklahoma Trails, but it's pretty obvious over by the apes. It's a massive building and it definitely shatters any illusion of a "natural" backdrop here.
@Coelacanth18 You'd think they'd switch up the order so the Lotus Pavilion was behind the orangutans, and *apparently* the ape exhibits are rotational or at the very least have the infrastructure to be rotational...
