I've glanced at Bryce4's claim to be able to import DEM's. I think my scales needed adjusting [the Z-scales -- not the ones on my hide >;/ ] I wasn't able to spend so much time on it, but it looked promising. Unfortunately, real life concerns and writing a novel get in the way of playing with all these 3D programs, and what little time I can spend has been in Poser & RDD building centaurs, mermaids, & scenes with dragons [to highlight my novel;)]. Keep plugging away at it & good luck!
