The "Modify" ssc command in Celestia 1.3.2pre11 has the side effect of removing all rotation information about the planet in question. I first noticed this when using the Modify command to incorporate Praesepe's (I think) Jupiter Rings add-on, with the following ssc:



Jupiter now has a day length the same as its orbital period.



This confirms the loss of rotation period information, and also shows that information about the tilt of the planet's axis has also been lost. In addition, the inner and outer ring distances are also lost.

Surely this shouldn't be happening, as "Modify" implies that all previously specified characteristics should be preserved.

I've found the problem with the rotation period as well as the wrong treatment of rings, but I don't know what the problem with tilt should be. Can you explain, or even better give an example?

Oops

I was misled by the synchronous rotation into thinking the axis tilt had been lost.

My mistake. However the point about the rotation period still stands.
