How to use falloff maps in 3DS Max.

[TGE]

material editor
in diffuse slot:
falloff (not bitmap)
in the black material slot, put the diffuse bitmap.
in the white material slot, put the falloff bitmap.
change the perpendicular/parallel setting to fresnel<--- IMPORTANT
you should now have this specular hair effect
if not, switch the bitmaps. i cant remember which bitmap went where

Worked.
