Blood spots appear when using "SSS Set Name".

When I include the head model in the collection, strange red dots appear on the nose. Is this a problem with my operation or parameter settings? 

 

 Please reply if you know, thank you!

Perhaps the displacement map is causing the voids inside the skin.

Check if the issue is resolved by raising the zero plane，0.55 for instance.

I think @oxdfang is right. I had a similar displacement issue that was fixed by increasing the displacement.bounds_padding.
