When im importing an animation from Poser 6 to Daz , my victoria 4.1 character loses all its head morphforms and expressions.Should this happen? and is there anyway around it?

Also , another question. Ive noticed Daz3d renders hair better in preview mode then it does in Poser 6 (sometimes only produces white meshes or the underside of hair has no textures). I do alot of 500-600 frame animations in Preview textured mode. Is there anyway to use the Daz3d preview renderer in Poser6?
