Okay, I did some more checking on how the textures for M4 work (see the graphic). Apparently, DAZ loads the top cuttoff version of the low-res textures when you first load M4 into a scene. If however you inject the low-res textures from the supplied Pose file. You get the non-cuttoff textures shown at the bottom which will work fine in SkinVue. I will add this issue into the Plugin Documentation.
