Hi Alex, The osgVolume::MultipassTechnique supports mixing geometry with the volume and constraining to a convex hull geometry. This is what you should use instead of FixedFunctionTechnique, the only reason to use this now is that you've have completely hopeless hardware+drivers that are incapable of doing proper volume rendering.
