Problem importing ForestPack from 3DSMax into UE (no texture, shows white)

Hi

I have created a carpet using ForestPack in 3DSMax.

It imports fine but the strands show as a white material in UE instead of the texture applied to it in 3DSMax (I use datasmith). Any idea what the best way to achieve what I want?
I have played with parallax occlusion a bit but the result is not satisfactory.

Thank you.

I tried forest pack too, but using blender + groom hair worked best for me to get a carpet done. There are good tutorials out there on youtube showing how to set this up.
