As images shows when ever i bent her leg this thing happen. i search around daz forum and saw do with some JCM but i'm not a artist programmer nor haven't used zbrush.
Is there way to fix this? and if i had to use to use zbrush to fix this issue how can i fix this?
I've had the same problem with two characters last week, both male and female. When the full body morphs were set at less than 100% the thighs and also the hands deformed when posed. The male one was Joel from LOU and the female was a toon character. My guess is that some characters are designed to have their FBM loaded fully or they will deform when in some poses. They're fine in the default pose but don't like it when the limbs are bent.
Question - do these characters only have a single morph dial, or did they have separate body and head dials?
I ask because I've seen it once, and I wound up uninstalling the thing (because I rarely if ever use a character morph with any dial fully set.) That character (forgot what it was) only had one big, fat dial.
Have a look under Pose Controls > Legs > Flex Quad (left and right) to see if the limits have become disabled. I've seen issues where, for some reason, limits have been disabled which can make those morphs apply in the hundreds of percent.
