Lets say i have four cameras.
Is it possible to view all of those cameras at once?

Would i have to have Unity3D Pro so that i can show the camera as a texture on an object?

Simply repeat the process for each camera.

  1. Yes, you need pro to render camera to surface, though there are some read from camera to create texture to apply to surface scripts out there. Check the Unity Wiki.
