Door portal to next scene

So I want this game to work with different universes, I know how to load the next scene on a trigger but I want the player to be able to see the next scene (Universe) through the door while opening it. Is this possible? Kinda like Portal where you see the second portal locations through it but then with a door and with a new scene that has to be portraid. Ive had some idea’s already on how to work it out but I thought asking here will help me a lot since most of them aren’t really practical.

Its not as easy as you’d think but its possible!

We might have an easier solution.

We made a tutorial on how to change scenes and end up in the right spot on our channel.

Hope this helps!
