Requirements:
If you build your HS2 setup from scratch you need:
-Bepinex 
-Bepis Plugins for HS2
-Resource Redirector 
-HS2API 
-HS2ABMX 
-HeadBundleRedirect for HS2 (check this if the makeup is misaglined)
If you use a repack then it *may* have all of them installed already

How to use:
Just drop the mods and UserData folder to your HS2 folder (no need to extract the zipmod file)
Load the included card then modify it if you want, I do not suggest building the character from scratch
Adjust the color of skin/hair/etc to fit your lighting setup
But the sliders don't work and you shouldn't change eyebrows/lashes/makeup to something else
Card with (Mod Neck) on its name has neck extended by 1.12 using ABMX and enlarged; looks better IMO but might cause animation issue
Use normal version should that happen
There's problem with texture stretching around the chin and also neck seam but only noticeable if you zoom very close
Optional Next-Gen shader textures included

Limitation:
-HS2 ONLY! Not tweaked or tested for AI as I don't have that game anymore
-No bones framework (for now) meaning limited customization, and compatibility with other hair if they clip
