If you're talking about textures, you need the original image files, Open Poser, go to material room, apply textures to object. I don't have a modern enough computer to run the lastest DAZ Studio so I might not know everything about this. Since DAZ Studio was designed to be able to open Poser files, it is often easier to distribute Poser files to be used in both systems.

I don't know if the procedure textures are compatible or not. If not you'll have to look for simular effects when converting for the other.

Sorry if I was not able to help you more.
