I dont know about the texture names being an issue or not...though that does explain why sometimes certain textures just wont show up half the time.  But I found a way where I can do this challenge and still keep my sanity.  For any of you having similar issues and want an alternative route, here is what I am doing;  Rendering a background in Vue.  Turning said background into a HDRI map.  Taking my model from DAZ into Bryce along with the new HDRI...render...clean...submit.  Time consuming yes, but at least I can get to the rendering part now!
