Hat and Hair Helper Genesis 2
Hat and Hair Helper Genesis 2 Daz 3D model
Now you have many more options using the Hat and Hair Helper. This conforming object (a version for Genesis 2 Female and Genesis 2 Male is included) fits invisibly into your scene, and when hair is conformed to it, you can morph the hair to hide it under hats, caps, crowns, hoods, et cetera. Because the conformer is used while invisible, it will not increase render time.
