the inability to directly export .obj .3ds is one thing about Bryce that puts me off. but it can be done, open the object (hilight it)with the list to the right hit the E so that you are bringing up the smoothing tool but at this point do a Ctrl-D and this will bring up export dialog box pick the format and where to send it just like other programs from there on. now you havethe model to use in another program.
