Robynsveil, from my experience with the remapped Posette, I think you should load the Terai Yuki V3 Cr2 and not the default one. I made the same mistake the first time I tried to use it. I am not sure whether this remapped Terai Yuki can take mat poses or whether you need to apply the textures in the material room. Did the textures "take" - appear on the figure? If they didn't appear I think you need to go to the material room. I apply the Posette and Dork textures manually and then save the materials to the library for future use, so I only need to go through the exercise once. DPH has to use different material zones to the original figures for copyright reasons.
