Thanks!
When you say ancient history, do you mean back when mars had water (probably never like in my picture) or back when I made a lot of mars pictures?
Anyway, tis one has a way to go, but just to have a working tgd with that kind of resolution is new. I tried to make some global clouds, but as nice as the easy clouds are for skies, I did not like what I got for the global look yet.
Cheers,
