Changing the default shader balls in 3dsmax

[MoonDoggie]

Hey all,
Does anyone remember how to change the default materials in the material editor? Mine keeps coming up with a bunch of A&D shaders when I "Reset Material Editor Slots". I think I remember it's some .mat file on my drive, but can't figure out where it is.

Thanks,
Colin

Found it! (Be sure to have your "Customize-> Customize UI and Defaults Switcher" set to MAX.vray

Hope this helps someone else.
