I've been working on some textures for Shadownet's unicorn and in using them in Poser, I've run into a problem. Whenever I get the unicorn looking the way I like and then save it back into the library, when I bring it up again, the tail has turned "solid": it is no longer wispy and it is no longer listed in the materials editor, so that I can assign material/colors to it. None of my transparency settings are changed.
