When I'm using subsurface scattering I had to change my textures (I've to bleach them, the girls become reddish).
But it is also possible to get good results in MH - well at least in my opinion. Before I started to learn blender, I tried to reach my results only using MH.
I was simply playing around with the litspheres. In both picture I use them only for hair and skin. When I take the litsphere from the first model for the second one it looks weird indeed, so every model gets her own litsphere.
I also reactivated the perspective code and put that in the animation modul of MH (well with some unpredictible results when you switch back to orbital view etc.).
But I was totally unhappy with things like polygon hair (which of course sticks to the body as you can see) and I wanted to understand more of 3D. So I use MH for what it is designed for. For hair and posing, location etc. I now use Blender. The only problem: For a picture I've to wait for hours (CPU-rendering) until it is finished. In MH this only takes a second. GIMP (for textures), MH and Blender: for me it is a perfect combination.
