Not sure if this has been asked before, I couldnt find it if it has, but I'm trying to do a render in which someone is taking a picture of her own in scene.

What I'm doing at the moment is rendering the POV of her camera with a dolly cam I've attached to her phone, saving that render, then assigning it to the screen material of the phone for the wider shot I actually want. So my question is, to streamline things a little, is there a way to assign a camera to be a material? I've poked around in the materials room and found a few things that looked promising, but got nowhere with them. Anyone have any ideas, or is the way I'm already doing it all that there is?

I'm hoping it isnt, as in an upcoming series of renders I kinda want to do a mall security room kinda thing with multiple CCTV cameras that will have changing scenes in each shot, and I'd very much prefer to just set up cameras and feed their view into a material to put onto the monitors, over rendering every shot individually and then assigning each monitor's display.

And if thats not possible, lets see that in Poser14 huh? ^_^'
