Thank you! That is the first thing anyone has suggested that has actually moved this issue forward.
So, I can’t find the spawned camera. Literally. I can find spawned cameras, one for each of the four local players. Just not the one that the PlayerCameraManager is actually talking to. Not the one that’s actually used for the viewport. So…where the heck is my camera when I use a PlayerCameraManager? I can tell that none of the spawned cameras are my camera because (1) they are all set to perspective, and my viewport is very obviously working well orthographically, and (2) nothing that I do to the spawned cameras has any effect on the viewport.
If I touch the PlayerCameraManager’s attributes in anyway, they instantly take effect (like adjusting the orthographic width, for example). The PlayerCameraManager doesn’t have a “constrain aspect ratio” option, unfortunately. And I can’t find the camera.
So we have moved forward (the spawned cameras are red herrings). But I am still stumped.
Suggestions?
