Hi Smokey,
…where you could actually see things in front of the train as you travelled along.
Do you mean a cabview (with or without cab) or with other words a driver’s view? If yes, that doesn’t exist in Rule The Rail. If that would be implemented, it would mean, to implement real tunnels, too.
At the moment the camera “flies” over the mountains, using its collision detection. But that wouldn’t make sense in a cabview. So we would need tunnel walls, otherwise you can see through the mountains from their back or inner side, as polygons are only rendered from one side.
Kind regards,
Willi
