Thank's for the tips. In fact I don't want to export .3ds format INTO Bryce; I want the oposite: export .3ds FROM Bryce. Why? Because I have several Bryce free models that I found in the internet, and I want to be able to open them in other 3D programs, like Poser for example. The 3ds format it's the most uniiversal format for exange models between diferent 3D programs.
