I am using Poser 5, and am interested in releasing some items to (hopefully) be used with both poser 4 and 5. My props (pp2 files) have references to materials (mine) which seem to be P5 specific (node). Is there a way to create props with material references that are backward compatible, thus requiring the same product for both versions of poser? Does P4 simply ignore parts of the pp2 that don't make sense to it, or does is really hate that? Your thoughts are appreciated!
