Cameras

[distant jolt]

The trick with cameras is that there should only be one locally in the scene. I prefer cinemachine for controlling the camera.
Check out the ClientDriven Sample from Unity. It uses the 3rd person controller and cinemachine.

I'm trying to stay away from client authoritative gameplay, though.

for the stuff I want to do, I want to raycast towards other players to allow / disallow visibility

if the client can be authorittative, the server has to decide every aspect of location.

I mis spoke there. if the client is authoritative it can allow for being able to see people / etc.

by raycasting on the server side of things and allowing disallowing positions, I can allow for other players to exist or not exist on the map.

IDK. I have read this already, and that's my two cents on clientnetworktransform, which I'm trying to stay away from. I will read it again though.
