How do i make something like portal_linked_door (video) (another video) or antichamber portals to achive non-euclidian geometry effect?

Trigger volume wired to a teleport or set location node in blueprints. you can put target actors in the level and reference them in the level blueprint to get the location to spawn to.

For the visuals I’m not as certain, probably a rendertarget on a plane with a camera at the location.
