If you look at other threads.
Were you trying to import Poser7?
Was it right IN POSER befor you saved for Carrara.
Which method did you use to import into Carrara?
Did you have light through transparency checked in Carrara?
Was the result as a Carrara save OK?
Save as that good Carrarra as  .car
Open that good .car file and save THAT as a .obj or .3ds.

Just ideas to think on.
