I think that KRS only allows two camera positions per camera blueprint. For example, I'm in the cab of the subway car and I had to define only two camera positions in the cab camera blueprint. I defined one camera position as the view from the train operator's seat and another position as the view as if the train conductor sticks his/her head out the side cab window while he/she operates the doors and checks to make sure that nobody gets stuck in doors when the train starts moving. How do I create another camera position for the other side of the subway car? Auran Trainz lets me define as many camera positions as I want.
