What is causing this?

The sky is cut in two.

It's your Virtual Sky settings. Try this:1. Get the latest FSUIPC from http://www.schiratti.com/dowson.html and enable the Virtual Sky settings on the Clouds page.2. Get the latest version of FS Sky World Virtual Sky w/ Alpha Blending3. Choose a lighter V-Sky shade; that's a pretty dark blue you have there4. In order for V-Sky to work, you must have a layer of cirrus below the V-Sky layer (which is absent in your above picture). Optimally a mid-level stratus or cumulus layer will improve the look. FSUIPC's Virtual Sky setting will do this for you.Cheers,JPS. You will still have a slight line anywhere you have an upper level cloud layer. This has to do with MS modelling the sky as a plane and not a hemisphere. There isn't much you can do about this. Below is what your V-Sky *should* look like (this was taken with V-Sky #12). You will see there is still a slight line, but you won't be able to get rid of it entirely short of restoring the original dull-blue sky color.http://ftp.avsim.com/dcforum/User_files/3dd89eb94c5449d5.jpg

Thank you very much. I thought it might have something to do with V-Sky. I'll do the changes you suggested. And thank you again.
