Thank you for your comment in post #1215. I somehow missed it.
... how did you create that sky
I learnt from the basic tutorial which is buried in a post in the sticky thread over in the Content Creators Support thread. You have to be logged in and registered to read it. It’s the one I mentioned in post #1217, link repeated
here.
To get an idea of where the coloured streaks might appear I used a test sky which is a basic black on white square grid. This helps to identify the distortions and behaviour of the sky which, if you watch one, isn’t displayed as a flat image above the baseboard. In places it is irregularly rippled. It is useful to know where those distortions occur in relation to the baseboard positions, and their orientation in relation to north.
It’s also interesting to see in which direction the sky moves, and how the distortion changes as you travel and turn across the baseboard. I'm still on that voyage of discovery!
The grid isn't part of the finished product though. It was simply used to understand how the sky works; I initially made it to see whether a large .tga file with hard black lines on a white background gives a better resolution than a smaller one. I thought that hard lines could be more easily assessed for sharpness than fluffy coloured clouds.
On my system 512x512 provides the best image. Anything larger gives no noticeable improvement.
I made the posted image from a sunset photo which has been modified through Gimp2. The four matching images, set into the conventional seamless square, initially gave me four bright yellow sunsets (3 too many!) and some very noticeable mirror imagery. I wiped and blurred these with the Gimp Smudge tool, set at different diameters to make sure that it didn’t look too smeary.
The image is still being tweaked. The angle of the sunset is not quite right, but I'm still experimenting with that and some other ideas.

There have been no colour changes in Surveyor other than what can be achieved by altering the time of day. I don't mess with the colour settings. That shot was early morning which tends to give slightly clearer imagery (before the heat of the day has has time to build up).
Apologies if this is a bit detailed for this thread. I was going to put it, perhaps with a few illustrations of the test grid and distortion effect etc, in the “How do you create a Sky” thread, but it won’t let me post. When I try to put up a reply it says, "Your user account may not have sufficient privileges to access this page".
