So I play on a forge server hosted on my PC with friends. Before we had lookingglass installed, cameras would work at all, I would bind them, right click, then click #1 and it would just bug out, I would disappear from my friends prespective, but stay where I was in mine. I decided maybe it was not having lookingglass, so I installed it. Now, I can bind 1 camera at a time, and can only view in from my hands, not in a full-frame POV. I right click and nothing happens! Please help.

If the server has LookingGlass installed but the client doesn't, unexpected behavior will happen. The fact that you can only view one camera with LookingGlass is intended.
