One of these days i might take the time out to learn Modo but more then anything i was curious to see how it handled 16bit grey scale maps for displacements. I might buy it to tinker with it. Digital painting/drawing various media seems to be more my interest. This terrain thing is more for the love of Geology and how software can mimic these things.
Also the color maps in Modo 201 were of the same color gradient maps that i had made and use in GeoControl as well.
