Robert, I'm actually planning on providing FixedFunctionTechnique as a fallback codepath for rare cases. As such, I was hoping to get lighting working with FixedFunctionTechnique. I'm confused by the interface of createNormalMapTexture. Specifically, is there an interface for passing the resulting buffer of surface normals to somewhere in the osgVolume/layer/tile hierarchy so that lighting sources can use this information? It's unclear to me what I'd do with the result of createNormalMapTexture. I can't find any examples of code using this function with a google search.
