Encoded as in pcf encoded to be sure that you have the necessary seed file. I think those are the right initials. The other is rte or something like that. (past my bedtime... again) Anyway, suppose that you have taken the head of one character and the body of another and want to distribute your creation... or suppose that you've made a passel of morphs and want to share the character... you can't legally give away somebody else's mesh. But what if the person already owns it? How do you prove it? You make sure that they can't use your file unless they have the seed file installed. There are encoders/decoders, but they are PC only. MacInstaller had a built-in decoder for one of them... so we didn't need to use a separate product, it was just part of the installation. DAZ does this with their own products all the time, for upgrades and expansion packs, but since they use installers with everything, you don't notice when it is looking for the right seed file. Unfortunately, their installer is pretty useless if you want to do your own organization (I install into a temp file and then use MacInstaller, which makes 2 steps). If you use mostly independent stuff, you'll need a decoder for some of it. Carolly
