well out of all these posts only Bea pointed this person to the one place for importing the models they have ;) When Bea said click on the .br5 scene file it will open in bryce for you, if you still have troubles doing it that way go to File/open then select the .br5 scene file and click on open..it should work fine that way for you. You can also open Bryce 3, 4 scene files that way if you come across any.

I have opinions of my own -- strong opinions -- but I don't always agree with them.
