This add-on represents my planetary design research (this is why it may feel "incomplete" and lack unified style) considering texture maps, planetary mesh (not 2014 beta feature!) and its mapping, cloud maps and higher levels of jovian atmosphere.
System contains seven planets (two of which are moons), textures are custom, made in different ways.
Tips: use time warp to see cloud flow over 5631 e; 5631 f is a hypothetical semi-gas or sub-neptunian, or call it whatever you want, but the point is that it has thick hydrogen atmosphere which lasts for miles above the rocky surface; try "diving" into 5631 e and 5631 f atmosphere, watch the gauges for atmosphere params, and speed of descend.
