Well, with all my renewed 3D activity I've decided to reinstall Bryce 7 Pro, as it's faster for some kinds of scenes than Carrara or Daz Studio. Amazing discovery - I have several gigabytes of Bryce content!
So, back into the downloads I go, and grab all my old Bryce stuff before it falls off the face of the earth. Who knows how long Daz will keep the older Bryce goodies? They still work with the new Bryce, but Daz has a history of dropping things past a certain point.. better safe than sorry!
