How can I render what a camera views on a plane?

I’m making a world I want to give the illusion of being noneuclidean. Some windows will be unreachable, however I want the player to see the render view of a camera that I place somewhere else in the map. So 1 player walks through a hallway somewhere, and another player sees that person cross the window, appearing as if they are in the building. How would I go about this? also, If you know any discords you think might be interested in helping me please let me know.

This is more of a Unity question than an Udon Question. You can place a camera anywhere on your map, then you’ll have to create a Render Material that you apply to the plane that you want showing the camera. Make sure within the Render material you drag and drop the camera object into the camera field.
