@Erlik- where did you see that? I looked at the rules and I quote-(rule #3)- "Pre-fabricated models are not allowed to be used. These include parametric models generated from Poser or Daz3D". When I use a terrain in Bryce it is never a "default" one. I either use the brushes or the filters to build from "scratch", or import a heightfield greyscale I made in PS.
