host error : PF_setview_1:not a client
The only time I came across this, it was some error with a camera shot that started the level, and taking the camera out fixed it.
EsBe says: As the name implies, this error occurs when the game tries to change the view of a non-client to that of the trigger_camera. What isn't so obvious is that the trigger_camera doesn't automatically target the player. It will target who-/whatever triggered the camera entity.
Note that the game can trace the "activator" back through multiple entities. For example, if the player walked through a trigger_once which triggered a camera, the game knows that the trigger_once triggered the camera, but it also knows that the player triggered the trigger_once. The same applies to a func_button, etc. I'm guessing that you tried to trigger the camera with a trigger_auto. This would cause the camera to try to change the trigger_auto's view, not the client's, because the player didn't actually trigger the trigger_auto. I would assume that this error would also occur when a path_corner, etc., triggers a camera.
i found this. not a mapper so i don't know what it means.
