I have been importing grayscale photoshop height maps into Bryce 4 and and applying them to terrains. This has worked out great for my custom landscapes ....however, when I import and apply maps that show shapes with sharp edges..they seem to "melt down" when I apply them to a bryce terrain. Is there anything I can do to use grayscale maps with sharp edges and produce 3D mesh which maintains the clean and sharp shapes? Thanks for your support!!
