>>glacier retreating… First, I would ask how does a glacier retreat? Does it retreat by slowly melting just at the leading edge, or more likely, by overall melting, sublimating, and settling over a wide area? Given a fairly hilly terrain (i.e., just been scarred by a glacier!), I would try modeling a single (fairly organic) sloped glacier mass protruding into the valleys from beneath the terrain mesh. (Use Displace and perhaps fractalize or a good bump map?) To make it move, my first thought would be to make a copy or two for morph targets, then manually distort the morph targets with a little vertex editing near the front (retreating) edges of the ice mass. Perhaps gradually lowering the sloped glacier mass while morphing would give the appearance of a retreating glacier. But then again, maybe not. <g> JKJ
