Project UV from Camera/Scene Capture?

Is there a way to project a game object’s UV from a Scene Capture or Camera’s screen space?

There’s a Unity asset that achieves this UV projection effect [click here for an example vid]](Project UV from Camera - Unity realtime Spherical mapping - YouTube), but is there a way to do it in UE4?

For example, say I want to take two angled planes (pictured below) and project the view of an observer onto them so that the resulting image appears seamless when viewed from the observer’s vantage point. This technique could be useful in creating images for a CAVE, for instance.

Another example application of this type of effect would be the portals in, well… Portal. The projection of a view from the other end of a portal is always from the first person vantage point.

Any update on this?
