We need more information. How are you separating the layers?
Are you using separate passes manually, or framebuffers?
The skin shader has explicit separate weights for the various components.
Manually, you'd 0 out all but the weight you want for your pass.

For using framebuffers, you might need to have several skin shaders each with an individual component isolated, and all sharing the same lightmap.

I'd make a Phenomenon to do this.

If you are using Maya 6.5 there is a new extra attribute (dynamic attribute) that can be used to replace a whole material with a Phenomena. See the Help manual. I haven't tried it yet.

Hmm, this would make an excellent example for the next LAmrUG in which we want to show how to use Phenomena from the UI.
