Hey Spit.:-)) Thank you very much for your help. We are almost there.:) I mean my autokey was off. I remember I did some changes at key thing when I was playing with rotate objects (I saw on manual something to do with keys) and after this I didnt work with Bryce. After lost graphics a lots I decided dont sleep this night to finish what I wanted to do because I was afraid to lost everything again. So, I received your reply and I followed your instructions (I saved several versions because I was not sure I understood about time selection versus time mode) and I got the same at all of them: I lost only the first mountain I did (used almost as terrain). Not too bad huh? I dont think is a hard drive problem: I am a norton holic. Maybe have some tool checked when it should be disabled, dont know.. And I think dont have any problem use mountain at terrains place: I did it already (before play with rotation) and it worked fine. Thank you a lots! Its not perfect but I can assure you Its not funny see a work lost, mainly because I am newbie with Bryce, so I spend hours to make only a mountain. Beth
