Development of the openBVE material was a two-stage process - first stage was to get the BVE4 routes to run under openBVE as you would see them in BVE4. Next stage was to update to current timetables and start to use some of the great new features of openBVE such as animated objects - this was a huge undertaking. My original plan was to re-write to get a good external cab camera image in both directions, but this would involve much more complex scenery and would mean a very severe frame rate hit, so I have stuck with "staying in the cab" optimisation.
