I've updated the shader used for creating CUA's from KK hair.
Kaede will receive the first of these updates, and her updated file is now on MEGA.
Its an overall upgrade in appearance compared to the old shader, and should fit together a lot nicer when combined with the anime shader as well.
The main issue I had with Koikatsu hair is that it will frequently look blocky when exported out of the game, due to a lack of cell a shader. This is because a lot of hair from KK are an amalgamation of different shapes fitted together.
By no means is this 100% perfect, as KK hair does have a layer of specular shine over the hair that I am figuring out how to replicate. But for now this is a substantial enough upgrade.
