I’m sure this can be done but I’ve just never looked into it. Maybe its with scenecap2d or something, but essentially:
Is there a way to put a camera somewhere that moves around, and on a tv screen or a tablet that the player is carrying they can look at the tablet and see whatever the camera sees in real time?
yep !
you answered yourself put a camera in the scene, create a scene capture asset and assign it to this cam, then use this texture in your tablet material and it should work.
