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,

If that's Cycles in Blender 4.0+, then try to separate the Eyelashes from the body mesh.

The Random Walk Scattering will bleed in colours from any connected meshes and doesn't take transparency into account. So the black colouring of the eyelashes bleeds into the neighbouring skin, which usually looks like blueish smears near the eyes and around the eyelids.

Or change the Subsurface scattering method to Christensen-Burley, which is much less interesting but doesn't do this.

Edit: You can also try turning down the Subsurface Weight in the material paramters. Depending on the skin textures the subsurface effects can get out of hand.

Many thanks for the quick response, and resolution to my problems, both amending the Substance weight and seperating the eyelash mesh from the body helped (still slight green hue but much better). 

Thanks again!
