Issue with motionbuilder to UE livelink using morphtargets?

hiya,

on morphtargets/blendshapes in motionbuilder they use 0 - 100 values and unreal uses 0 - 1 numbers.
im getting the huge scaling effect on my morph targets.
do you know if there is a work around on this in BP or in UE chnaging the values on the targets themself to use 0- 100?
or do i have to make a converter setup in motionbuilder for my face rig to output 0 - 1

cheers!
