I was not expecting (and greatly appreciate!) the quick responses to my problem.
 Since this is the second time (2 out of 2) that the use of blob objects for
creating craters has been mentioned as a possible solution, I would like to try
this approach.  I can understand how "negative" blobs could be used to simulate
the smooth dimples of a golfball, but the rim of an impact craters wall is
usually sharp, jagged and abrupt. the same is true for the more complex
features of the inside of very large impact craters such as central peaks and
peak rings.  Is is possible to get such "sharp" effects and still use blobs?
