Hey mikerz, Are you sure you're providing all the necessary BitmapData's in the constructor, and not just null (for normal map or environment map for instance)? In the blogpost introducing the material, there's an example of how to use it, maybe it helps: http://www.derschmale.com/2010/04/21/fresnel-reflective-shading-with-away3d/ (there's a link to source somewhere :) ).
Hope it helps!
