Well, SSS will have made it a christmas card for next year... :)

By "not much control" you mean really "no control at all", isn't? I
think this is a "feature", the main feature for a sky model, IMHO: I
don't have to think on the colors. Of course, you can always ignore
SunColor and use whatever you want for a concrete artistic effect. I
tried for example using a blackbody between 2000 and 6500 K, depending
on the altitude, and it also works nicely.

Yes, the mesh is a bit slow to generate when you need great detail on
the sky, to avoid seing the triangles. I hope Phillipe will have the
time this year to add the save/load feature for the mesh.
