If you’re using the set Jaderail posted, that’s a Daz only product. For Poser, you’ll need to add in a math node between displacement and the image_map and set it to subtract .5. This is only needed when using DS bump/displacement maps in Poser. For maps made for Poser, you won’t need to do this.
From there you play the the displacement amount on the PoserSurface node, mindful of the units you have set in Poser’s general preferences.
If you want more of a 1-click solution for Poser, Zev0 and Draagonstorm have a Vascularity product for M4/V4 at Rendo (currently on sale for $5.56).
