Scaling Ratios for G3/G8 Texture Maps

Gregorius

I finally got G8 and all her morphs working in Poser, so I'm starting to assemble a custom texture set.  What are the scaling ratios of the face, torso, arm, and leg maps for G3/G8?  For example, if I use a repeating pattern to apply freckles, should the spots be denser on the torso map than on the face map in order for the density to look consistent across material groups when rendered?  Thanks in advance!
