Hi there, 

I've done as much digging as I can and can't find an adequate solution for this problem:


Using the vanilla import with no changes (only for reference no troubleshooting):


Tried with suggestions found here, but still no luck:
materials - How to use Subsurface Scattering in Principled BSDF - Blender Stack Exchange




Amongst other settings. 

Really hoping to get this fixed! 
CC4 & Blender Addon is updated to latest (as of 2nd July). 

Many thanks,
