V3 has "empty dial slots." This is where the injections go when you inject morphs and ERC morph control dials into her. When these empty slots aren't injected, they are still there, but they are hidden. When you save a copy of V3 to the character library, Poser unhides all those empty dial slots. That's why you get the "-" dial names all over the place. If you run a saved V3 cr2 through Dial Cleaner, it hides the empty dial slots that should be hidden, the ones that weren't injected at the time of the save. As I understand it, Injection Poser Builder looks at a V3 cr2 and doesn't really care what's hidden and not hidden. It's looking for morph dial settings. You can inject all the dials into V3, make a character morph with those dials, then remove the injections -- IPB will still be able to see those dial settings, because they are still there. They just aren't acting on anything because all the morph data has been removed. So, make your V3 character morph with injected dials. Remove the injected dials. Save the uninjected character to the character library. IPB can look at that cr2, figure out what the dial settings were prior to injection removal and make INJ pose files that inject only the morphs that character needs, at the proper settings you had. Once IPB has made the INJ pose files for you, you can always get your character back by simply injecting her with the INJ pose files you made in IPB. And she'll only contain the required dials/morphs, so she is optimized as far as RAM goes. BTW, you want to remove the injected dials prior to using IPB because it makes IPB faster -- far less data to parse.
