How do I make portals /gateways?

I’m sure there’s a better terminology for what i’m trying to do.

But basically I have a model imported from 3ds max, textured and playable as a 3rd person walkthrough…

Now I want to add a doorway or portal that takes me to another level / completely different model but as I i’m not even sure of the name of what i’m trying to achieve I don’t know where to look.

Could anyone point me in the right direction please?

If you want to go to a different level, you would use a trigger first. When the player activates it, you will want to have your BP open the other level.

I found Kitaku’s book to be a good start :
