Since I work on a Mac, I have to manually load all of my Poser assets into the Runtime. The templates are generally UV maps produced by the merchant to allow users to create their own textures. I know that some products include texture templates, but I never bother with them. You can create a templates directory if you wish. My guess is that it would be within the Runtime directory (i.e. Runtime/templates/...)

Daz Studio doesn't use python scripts... those are for Poser. You can get around them with most products.
