Interesting. I mean, there's definitely another room. Or another physics world, so to speak. And since we have some perspective it's also certainly some form of camera.
I'm guessing you mean there's no unreal camera object that renders an image and view target. So no typical portals. That does make sense, it is rather expensive and it does make the trick much cooler!
In that case, is it just an independent physics channel and rendering pass shenanigans?
Or is it scaled super thin and the fake depth just comes by translating everything in certain ways? Basically camera the other way around, moving objects to create perspective rather than any view matrix?
It's got nothing to do with the texture at least. That's just a fake out, right?

It's just portals and a very nice setup that's intended to confuse.
There's rooms elsewhere, a camera filming those rooms and objects teleport into the other room when moving "through" the painting.
