actually all I do to speed up import/export transfer is create an alpha plane or a terrain in Vue PLE (or Infinite or Xstream if you own them), assign a material, select  and export it as .3ds object  paying attention to check color and bump maps and map resolution at 400x400 and then simply import into Carrara; in the linked image walls painting, wood floor, wood side tables and sofa texture were made this way; obviously with Carrara you can reach same results but in Vue there are many excellent prompt shaders so why not to be useful of?
