Glitter Shader

I made this shader when I was inspired looking at older pokemon cards and wanted to try to imitate the foil sticker look in Unreal.

Technique

The trick to it is that I am superposing a UV noise texture on a mesh and that same noise texture aligned with the Camera. Where they intersect, I shoot the emissive value way up! This is a similar technique as the glitter for the sand and snow in Octopath Traveler.
