I have a bunch of Bryce files that I downloaded a while back that I never installed. I now notice that they have ".BRY" extensions. I do not see anywhere in Bryce 4 that these files can be imported (i.e., into Sky, Material, etc. settings). Does anyone know if ".BRY" files are usefull in Bryce 4, or are they from some older Bryce version fie format and are useless now?
