Portals with a view or a TARDIS effect

So lets say I want to make a TARDIS from Doctor Who. I’ve got the box with a doorway on the front. I can make walking through the door teleport the player to an otherwise inaccessible room hidden somewhere on the level, but how can I make it so that you can see “inside” the doorway to what’s actually going on in that room? As in a full 3d when looking at it from the front.

In the sample content provided by epic, there is a level streaming example that uses colliders to load sub levels when you get close. That would then allow you to either move the Tardis into the collider to load different levels from a fpv or if the Tardis is in a fixed position then a collider in the Tardis would load a level as the door opens

Hope that points you in the right direction

Thanks ! I was looking at that a bit, but it’s the 3D effect that I was trying to figure out, I didn’t think of trying to orient the camera along with the player, but that might be a way…

Regarding the level streaming, the issue is more “seeing” what’s going on in the level, I might want to have animations or particle effects already running in the Tardis, that you can see from the doorway before you enter, hence my thought of it being better to have it as a hidden part of the current level, rather than loading a different level when you cross the threshold.

Ah yup, you’re right in that one. Well not sure if I’ve got the math for it, but I’ll give it a shot, it ought to be interesting. Shame there’s no easier way to pull that sort of thing off.
