I think you really do need patches. The Poser patch can be downloaded from the Curious Labs site. The essential Bryce 3 to 3.1 patch is obviously not current, but you can get it at Brycetech. Poser, when you export an obj, should give you a dialogue box with three options asking how you want to export groups and stuff. If you don't see it, something is wrong. You don't really need to smooth a Poser obj file in Bryce. Upgrading from Bryce 3 to 4 is really worth while if you want to work with Poser also - if you can still find B4. Textures should be loaded in the far LEFT window. The middle one is for masks. When you say "doesn't work" what happens? If it looks jumbled, that's because with Bryce 3 you have to rotate the texture in X by 180o.
