have you checked out any other planets people here have made?  i've done
some.  my latest (which i haven't posted) is pretty darn good in my
opinion.  i think i posted some source in p.t.s-f.  just look for my
name as the poster (postee?).  i based my atmosphere on jeff lee's
tutorial, but changed quite a few things.  i used image maps which
you'll have to replace with your own.  good luck.
