I'm trying to simulate the metal flakes that you can see in this helmet. It looks close to a metallic paint + flakes, but it definitely is something else.
I found a few materials that come close to it, like Mike Pan's Car Paint Material, but if you look at the video it seems to only show up when it's in the specular and there's a bit of iridescence to it. Also, it completely disappears once it's outside the specular glow.
Do you guys have any idea how to approach this? Any idea of a material that's a bit closer to it?
