Workaround for exporting 3dsmax modifier animations to Unity3d.
Export Noise, Wave, Bend, Twist etc... to Unity3d as morpher vertex animation.

Turn Default IN/OUT Tangents for New Keys to Linear!

Max script:
copy this code and put your Objectname(Cylinder002)  and Framecount(0 to your Framecount) in it:

with animate on  for i = 0 to 250 do (slidertime = i;WM3_MC_SetValue $Cylinder002.Morpher i 100.0;t = i-1;f=i+1;WM3_MC_SetValue $Cylinder002.Morpher f 0.0;WM3_MC_SetValue $Cylinder002.Morpher t 0.0;)animate off
