I strongly suggest that folks take a look at Frederic's Joint Parameter fixes for the knees and elbows in Free Stuff. Download the file (.pz3) and examine the thighs, calves, and shoulders (not collars) with the joint parameter window open and make the same adjustments to your P4 figures. In fact, the symmetry command takes the burden of copying the JP settings to the other side of your model, so you only have to change the settings to those three body parts for the left side, and let the symmetry command do the right side for you. [Frederic's model only comes in P3 format. They are the same JP adjustments that Yamato made to her Nene character]
