I always loved the Skinshade 4 MatCap from Zbrush, especially for stylized/anime characters. I don't know, but it really fits well with the anime characters and it really makes them stand out. Here's my attempt to get it looking like SkinShade 4 in Unreal using my old Cammy model as an example. Please let me know if I was able to copy the style or not.
