Uranian Moon Texture Misorientation?

[Hungry4info]

Taking Celestia 1.6.0 back to the time of the Voyager 2 flyby, I find the visible surface of the five large moons of Uranus to be almost completely covered by the LOK mask.

Can anyone confirm?

Looks ok in the latest SVN. (I don't have official 1.6 on this OS). Are you running any add-ons?

[Hungry4info]

I do have add-ons but none that affect the Uranian moons to the best I'm aware.

I'll redownload the official 1.6.0 and take a look at it in there where it won't be affected by add-ons that have slipped my mind. If it's okay in the latest SVN, then it may not matter anymore anyway.

[Hungry4info]

Just checked the official 1.6.0 and it was fine. It's just my set-up then.

I appreciate the double-check.

That then raises the question of what it was that was causing the texture reorientation. Any chance you could try to identify which add-on caused the issue?

I found the problem.

I've incorporated the maps of Uranus' moons Ariel, Titania, Oberon, from Steve Albers's page and colour-filled the areas on the map where there's no imagery. It seems these maps are misoriented with respect to Celestia... I confused the colour-fill with the LOK mask. After rotating them 180° (and a 180° longitude shift), they match Celestia's textures.


So in summary the issue arises from using Steve Albers textures instead of Celestia's default.

To illustrate, here is Ariel, for which I've made the correction, and Oberon, for which I have not.
