Okay, there's a couple of versions of this. In general inj stands for injection - meaning you add something to the figure already in the scene. There's MOR poses, which set the values for the morph dials. If you have Victoria 2, for example, and you have a character that you've customized with several of the V2 morphs, you can either save the entire thing as a new character (which takes up a lot of hard drive space) or you can create a MOR file which injects the morph values. (It's saved as a .pz2 pose file.) You would then load V2 and then doubleclick the MOR file. Voila! You now have the character you designed earlier. This saves on hard drive space. V2 is 21MB. Imagine having 10 unique V2 characters - that's 210MB of space, besides the original V2 .cr2 character file. A MOR file is only about 100-200KB. It would save you almost 200MB of space to use just 1 V2 and use the MOR files as needed. I think there's some utilities out there to make MOR poses for you. The few I've made have been by hand. I save the character, go into the file and strip out everything but the morph dial settings. Yes, I'm a masochist! There's a new type of inj - morph injection. In order to save space, DAZ created V3 and put all of her morphs somewhere else. You then load V3 and INJect only the morphs you want into the character. You can also REMove morphs if you decide you don't need them. A truly loaded V3 is about 100MB. The base form is 2MB. Even if you go truly nuts on injecting morphs, you probably won't get near the 100MB of the fully loaded V3. You can either save the new character -or- you can use DAZ's INJection Builder which will create a file that not only injects the morphs you need, but also set them to the values you want. It's a nice little utility, but it only runs for V3, I believe. I hope this explains it. If anything isn't clear, give a holler.
