I was wondering, at what point did the first unreal had portal support? Did it have it since it's inception around 1995? I'm wondering what the first engine was to have them. Unreal is the earliest I can find.
If you want to include 2.5D Engines ... Build (Duke NUkem 3D, Shadow Warrior, etc...) had them. Or were you strictly talking about Unreal and/or full 3D Engines?
But in all those Engines (Unreal included) it was more like teleporting (while keeping momentum though) and a (seamless) view to the target area. You weren't half here, half there.
