Esther,

You can adjust the depth of field using the camera focal length.  The higher the focal length the greater the dof.  Using your top view, you can  see lines in the camera field of view showing the area that is in focus... anything between the lines is in focus, anything between the camera and the first line and beyond the second line is blurred.

1% is usually fine and, for a still image, I would recommend Hybrid 2.5 in the render blur settings over distributed ray trace which is pretty noisy.

Looks good... glad it worked.  My advice was the voice of experience.  I did the same thing once and was lucky enough to discover the nuance before I flung expensive hardware across the room.

I'm sorry I wasn't more clear Lyne.  I think you accidently advanced to a frame other than the first frame (little slider beneath the pose window) in Poser before you posed your character.  The result of this is when you import your pz3 into Vue and select import single frame and leave it set to frame 0 (default) in the frame to import box... your character will come in with no morphs applied.  What I was suggesting is to set the frame to import to frame 30 in Vue as this frame would almost certainly be beyond the frame you had set in Poser when you applied your morphs and so the character will import with all its morphs applied.

I hope this makes sense.

I think what you did was pose V3 in a frame other than zero/one.  When you import into Vue, you are importing frame 0 (default pose).  All you need to do is import single frame 30 and you will have your pose intact.

I am just guessing but it is an educated guess as I chased this same problem around myself once.
