Unfortunately, it just what it is right now. This is more a function of brightness blending. If you put is in a brighter background then the halo would show up so much, if at all.
For 7.1, I’m looking into adding in an auto brightness adjustment for the hair. This is a little tricky though because it can look different depending on the background choice and the screen brightness. So I’m still trying to figure out how to make it more automated without a bunch of confusing adjustments like EZGS 6 had. This is one of my winter projects.
