This pack of sky_dome ships provides over thirty different vehicles with which to decorate your project's skybox. They are divided up into four side .lvl s with resulting smaller file sizes and greater ease of use. Such as all, imp, cis and rep. A brief editing tutorial with some examples which can be copied and pasted with an ordinary text editor includes an example of cis rockets (technounion_dome) which are descending rather than rising up.
