May be I will retry in future to use explasm, bt honestly it gived me more headackes than actual info that I couln't manually find out by myself so far, but yet again I mostly dealt with realistic Earth like planets apart the one I did for Ausur, but even there I slightly altered features of the planet like size, density ,gravity and atmosphere but to very small changes to get a desertic worldscape mostly, its a delicate balance seems , as soon as you move a number here or there everything unbalances and life sustainability becomes difficult.
