Quote - When fingers bend- the knuckle are supposed to pop up. No doubt- this could be done with a JCM.  An ancillary question: could this also be done using a displacement map with its strength tied to the joint bend ?  A joint controlled texture? 

Good questions, and while we don't have all the partial body detail morphs like this created yet, we do plan on releasing a morph pack full of body sculpting morphs like this.

This is something we'd love to get community input on - what PBM's are the most used, most desired, most important for such a pack? Make a list and chime in with which ones you feel are most important so we can begin collecting data for which things we should spend the most time on.
