It's pretty self explainatory. INJ files add morphs REMs remove them. They also have a little Plus or minus in the thumbnail incase you forget what folder you are in. :D Having Just got V3 and played with her this afternoon, I have to say I LOVE the Injection concept. At first it seemed like it would slow down my character designing by adding an extra step, but actually once you get the hang of it it's faster because you don't waste as much time looking for a morph in a huge list. Another brilliant thing was once I was happy with the face I created I spawned a morph target and hit the REMove all face morphs button. and I was left with a nice clean character with just the one Morph target. which I can now add expressions to. :D
