SVDL has a tutorial on how to create displacement maps in Poser using 2nd Skins. I've been trying, largely without success to replicate something simliar in Vue. The net effect is that he subtracts the base skin texture from the 2nd skin texture to create a displacement map. Works well in Poser, but does not work so well in Vue.
I'm hoping someone can point me in the right direction.
Here's what I've done so far:

1. I first tried to copy Svdl's method directly in Vue in a single layer to create my bump (displacement) map. Does not work as the displacement affects the entire texture, and not just the clothing areas.
2. Created a mixed material, using the base texture first, then the new displacement layer as a second layer with the same results as before. (Both textures showing displacement)
3. Same as 2. above, but created a distribution map using the same process as for the displacement map for the two materials. This had better results, but I am having trouble creating the distribution map in pure black and white.
   Several questions have arisen from playing with this:
   1.) how do you get displacement to affect only certain areas of the texture map? Nothing worse than seeing your figure suddenly swell up as if it were allergic to a bee sting.
   2.) How does one obtain true black and white from color images in the function editor? (I can get gray scale, but I need black and white.)
   I'm attempting to do this without having to create  other texture maps.

I would include images of my settings, but I'm on a Mac, and haven't learned how to do screen captures yet.
