Thanks to @Altasigna's help, I might be able to finally make a visor shader. If I do get this to work, you won't need to render the visor separately!
@MTSstreetlight This is it. But now I have big problems with my eyebrow, it doesn't curve quite right, and so far I don't know how to move it left and right
