The reason it doesn't work to have nested sub-dirs in Poser4 is that P4 is hard-coded that way. It's not that a CR2 in a nested folder can not find the path to the OBJ... Poser actually can't even SEE any content you might try to put in a nested dir. It's hard-coded to only look one level down in libraries. :( Bad. I'm assuming (ha! you know what that'll earn me) that when you set up an external Runtime in P5 you define the root, so this would not be a problem. OBJ references work just like an html link, as you said. If your CR2 points to Runtime:whatever.obj, the program should look forward in the directory tree relative to the CR2. If it points to ..:Runtime:whatever.obj that should look backwards in the directory tree relative to the CR2. But if you start with : that says go back to the root and look forward from there, losing all dependence on the location of the CR2. Similarly, if you have a web page www.me.com/contacts/index.html you can call up that page from any other page on your site no matter where it is located by using the URL /contacts/index.html. And I have no idea why I just typed this. :) I think I may be a tad obsessed. CL, it's daylight in California now. Come answer the question please. ;) Phoenix
