Max 2009 Flakes?

[TwoOneOne]

With the "Car Paint Material(mr)" and the "ProMaterials: Metallic Paint" Materials we have access to metallic flakes. I guess those flakes are done with some sort of procedural map. I had an Idea where i wanted to use those kind of flakes in the specular slot of let´s say an A&D mat. Basically that could even work but i can´t find anything to unhide this flakes shader. I found an entry in the "adsk_Mtl_MetallicPaint.mi" which looks something like that:

    # Flakes
    #-------------------------------------
    shader "flakes"  "mi_bump_flakes" 
    (
        "flake_scale"    = interface "f.flake_scale",
        "flake_strength" 0.8,
        "flake_density"  0.5        
    )

that somehow ensures me that there has to be some sort of flake shader which can be unlocked.


So the question is:

Is there a way to unhide and use that flakes shader?
