A suggestion from a fellow Poser user (assuming that this is a Poser-related issue):
Load up the ORIGINAL Shadow Dancer oufit into Poser, WITH the original Shadow Dancer textures applied.
Then MANUALLY load in the relevant textures from Wayii's set (via the Material Room), for each material zone. Once all the textures are loaded in, ADD this to your runtime as a NEW MATERIAL SET (click the + icon to save, then click on Material Collection in the window that opens - click on Select Materials to open another window - click Select All, then Okay. Give the set a NAME, and click OK to save). Once this is done, you can easily apply the texture set via the Material Room. You will need to repeat this for each texture variation - but once done it is simple to reuse them.
You may need to tweak the Material Settings, although by using the original Shadowdancer Outfit as a starting point and loading in Wayii's textures, you should be fairly close to a good result.
Please note that there are large differences to how Daz Studio and Poser handle textures. It is an issue in both directions - most Poser created texture sets don't render very well in Studio by default, and vice-versa. Usually some adjustments in material settings will be required. Just a fact of life, unfortunately.
Cheers
