I usually save mine as object presets (OBP)Once I have finished a model, I group it together ( making sure not to include the camera in the group..LOL) then I click on the triangle next to "create" at the top of the screen, this will open your objects library. Then you click on the triangle next to "installed" at the bottom left which will show a drop down menu: select "user". This will give you your user object library. YOu then click on "ADD". A window will open allowing you to name your new object and write a description if you want to. Then click on the check marks to close each window and your done. To show them in the freebies section or anywhere else you would then export them as obp's from your user objects library. I hope this helps as I am new to Bryce myself and don't even know if I used correct terminology:)But if you can understand what I am sayin gthis will do it for you.
