Question: How can I look back? I want 360° rotation during on-ride, not only 180°.
As Luuknaard says, you can only really do this from the "Interest" camera (the right-hand of the 3 different camera position options).
To be more specific.... The "Interest" option cycles through several different camera positions around the train as you keep clicking. The 1st one (which is what it defaults to when you choose "Interest") is what you want. In this mode, the camera can be rotated in a circle around 1 specific seat on the train, and can be zoomed in and out from this seat. So, the basic idea is, you get in this camera mode, which defaults to being a bit above and behind the train, then rotate the camera around so it's looking backwards down the length of the train.
HOWEVER, the seat around which the camera pivots in this mode is determined by which car/seat is selected in the POV camera mode. This is important because you can only zoom in to within about 4m of the selected seat. The default seat is car 1, seat 1, at the very front of the train. Thus, as long as this seat is still selected (which it is by default), the camera will always be about 4m in front of the train. If this isn't what you want, then before you got to the "Interest" camera, you first need to go to the POV camera and change it to be some seat towards the middle or rear of the train, THEN change to the Interest mode that orbits that seat. Now you can aim the camera to the rear and then zoom in to whatever point along the train you want the camera to be.
