Hi Acadia, the answer is yep it can export .objs to Poser and your default settings shown should work just fine--one thing about Carrara (if you want to use the materials room to change the textures on the .obj)--each part of the obj should have its own color--this is an example:  suppose you make a balcony.  You will need a fence, floor, a wall, and perhaps a wall with a doorway in it.  Color the fence red, the floor blue, first wall orange and wall with doorway green.  When you save the scene (after grouping fence, floor, wall one and wall two together) and export it as an .obj.  When you pull it up in Poser and enter the Materials room you can make the fence rusty metal, etc, your floor a tile, and your individual walls, stone, bricks etc.

That may also answer your question on why you would want to create stuff in Carrara (like walls, furniture-tables chairs etc for export into Poser.  These are very easy to make-and the furniture, goblets etc look very realistic.

Carrara looks overwhelming, but it really isn't and we can get you up and running within a week.  Jan
