I have managed to recreate my UDK portal in UE4 (kind of). It is not in usable form and is not optimized. But if anyone is interested in creating portals, this might give you some ideas.
Here is the Scene setup and Gameplay demo
- [Portals using UE4 Blueprint : Scene Setup][1]
- [Portals using UE4 Blueprint : Gameplay Demo][2]
The blue print is shown below:
Problems:
- It uses a large Render Target (same as the screen resolution), which results in low FPS.
- I hardcoded several things like resolution, eye height, active camera into the settings and blueprints
- I could not find an option to set a near clip plane, so the illusion fails if player is too far away (other stuff will block the portal)
If anyone is interested I will try to make more screenshots of other assetts as well.
