"Actually ynsaen - the textures are derivatives of the mesh as the UV's dictate the placement of textures. Without the mesh or the UV's in question to base the texture on - you are stabbing in the dark. As such, textures can be classified as derivative products." That's a reach -- and a long one in the wrong direction. It's based on not understanding the legal use of the word derivative as it applies in these cases. Seriously -- textures are not derivatives of meshes. Now, the UV Map itself, if one created and owned by DAZ is used, may be used to create a derivative work but that still doesn't make it a derivative of the mesh -- only of the image of the map.

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
