I'll try more later! Sculptris looks very cool. It looks (...) (14 years ago, 29-Sep-10, to lugnet.cad.dev, FTX)

Hi Bram, Looks stunning. Downloading now! Now if I could find some more time for LEGO I could actually build the horse I sculpted with the earlier version of LSculpt. (URL) Jaco (14 years ago, 29-Sep-10, to lugnet.cad.dev, FTX)
