I've been running five different runtimes with P4 PP (one at a time, of course) and after I gave DAZ Studio the go to find my other content it was able to load a DAZ Charger Pz3 from Drive F and use the textures and obj stored in my P4 Animals runtime on Drive E. I think it is like PBoost or Correct Reference- it needs to run a search to catalog where everything is. After it has done that it seems to work. I imagine a really EXOTIC setup could probably fake it out quite nicely, but if you have used the standard runtime hiearchy, even in mutltiple runtimes on different drives, it seems to work 95% of the time. I think you need to consider also that if the Poser files already have "Incorrect References", which is likely the case in those other 5%, that will lead to a missing texture map that has to be found manually. Obviously-then- either DAZ will provide a better search mechanism- or someone like Horseless Headsmen will provide a plug-in utilty optimized for DAZ Studio! Since DAZ Studio is starting from 2004 technology, this could be MUCH MORE accurate, especially using the new DAZ indexing file- something Poser doesn't have.
