My Skin Material Renders Pitch Black

[dro]

For some reason my skin material objects are rendering completely black. Yet if I change the material to something else, it renders fine. It only seems to happen with the translucent materials. The render only shows a black silhouette of the object.

Has anyone encountered this problem?

To those finding a similar solution. Make sure your raybouncing is turned up (although mines was already). The solution for me was turing off one of my lights in my lighting setup. Don't know why but thats what it was! It works now.
