Issue with SSS from Substance to Arnold (Maya)

Hello, ive been trying to to export the subsurface scattering effect that i created in substance painter in my current proyect to arnold (maya) and then plug it in the hypershade to apply it to my model, i followed an internet guide to do it, but its completely a mess now... im connecting the scattering map that i exported from substance to subsurface-weight in arnold and then setting it to raw and alfa is luminance but i get a white model... its driving me crazy because is the only thing left to do with the proyect, thanks for the attention.
