Sway, again

Hello,

The sway in TRS22 is not quite what I would expect. I am not referring to the external view of the body, but rather about the view from the cab.
In the first place, the motion is not realistic. It is the opposite of what I expect. It is more like the game is simulating superelevation of the track when it is not there. The body shell should tilt in the other direction than it does, if it would respond to centrifugal forces. For instance, on a sharp turn to the right, the roof of the train would move to the left with respect to the rails, and the skyline would rotate to the right clockwise. Not so in Trainz. Moreover, it is like the viewer is detached from the body, not sitting or standing in the cab.
In my models I use the config.txt option "outside-visible-from-cabin 1", since I use the actual body model as cab interior. The "interior" file contains only the controls. In this way I can also move through the compartments of the train in a realistic way, or look at the exterior by moving the viewpoint.
I found out that using this option changes the sway behavior. The A-cab is now free of sway and remains level with the outside world (with the track probably, but I have not tested superelevation), whereas the B-cab now gets in full swing: it sways, rocks and rolls more than without the aforementioned option.
I conclude that the A and B-positions are not equivalent in this respect. Moreover I found that the further the cab controls are removed from the origin (0,0,0) of their mesh (it is the point of the cab-mesh that will be connected to a.cabfront and a.cabback), the wilder the motion of the B-cab gets, looking from the cab interior to the outside world.
Anyone else dealing with this?

Regards,
Paul
 
I've never dealt with anything like this. In general, I minimize the cab sway because it gives me a migraine-like headache due to my own sight issues. With this behavior not being what you expect, there's a possibility it's a bug. Report this to N3V via the form.

 
Hi John,

Thanks for replying. I have not read your reaction before, since I have not been here for some time.
I think I will leave it for the moment.

Regards,
Paul
