To make JCM correctly, you need to create a morph to cover the poke thru, then add the JCM call to it. When you get down to the bare bones of it, it can be as simple as adding 4 lines of code to your cr2 and some *load into Poser, conform, bend, see if there is poke thru still, go back to cr2 in text editor, tweak, save, load into Poser, conform, bend, check for poke thru* tweaking. valueOpDeltaAdd Figure 1 BODY:1 deltaAddDelta 0.013 <-this is the tweaking part This is the main control for JCM to work. This needs to be added into every morph you want to turn into a JCM. It goes directly below the interpStyleLocked reference. Rob Whizenant (sp?) has an excellet tutorial at his site that will teach you how to add JCM to your clothing, but your JCM is only going to as good as your morphing skills. Good JCM work doesn't cover up bad morphing. Also Jaager over at Poser Pros is an utter genius. He's got plenty of info posted on this technical stuff.
