Not tested in Daz studio is often that a vendor doesnt use Daz Studio and hasnt set up materials for it.  Most itejms will work in Studio but can not use Poser node based materials. 

If you can set up materials in Studio you could easily do your own textures. Image maps will  work in either.

 Smith Mico has a 30 day trial download of Poser. They do hold funds on a credit card though.
