> Quote - Are you sure that it does not?

I'm pretty sure that it does not mirroring left to right. I have tried everything I can think of. In the image above is the Poser Frog. Note that it is the Bend parameter and the weights for the "Right Bulge" that are being displayed. Also note that the "Right Bulge" is actual the top bulge, and the "Left Bulge" is actually the bottom bulge (Kafkaesque).

An exaggerated bulge has been made on the left side of the head (see arrow). I then used 'Figure > Symmetry > Left to Right'. Everything looks the same, the bulge has not been copied to the right side.

If you like I can send you the pz3.
