Yeah, $300 dollars US seems very high given that the earlier iteration 'Super Erosion' is only $15 at the Cornucopia Store. Still, having used that piece of the GeoGlyph package, I found it very impressive. Also very slow. Working in the World Machine environment to create height fields seems more fluid to me then my less then satisfying forays into TG's node network. So despite the fact that this 'macro' costs as much as the host app, I'm considering it. While TG may be able to duplicate all of the aspects of GeoGlyph, I've come to question whether the time invested trying to accomplish that might be more then the cost of the $300. Still, that's pretty pricey considering...
