Hello,
Since Lain was a favortie of mine, i gave your idea a try :
Go there :
github.com/AlucardDH/dh-reshade-shaders
You need
DH_Lain.fx and the 2 textures :
lain_blood_1024.png and
lain_cloud_1024.png
The blood texture could be better but you can change it
There is also a few parameters to customize the rendering to your liking.
