This shader creates a procedural flake normal map that can be used for materials such as car paint.

Flakes to Normal Camera

A typical workflow would be to connect flakes to the 'normal' of standard_surface.

Flakes to Mix Shader (Mix Weight)

You can also connect the mask (alpha channel) of the flakes shader to a mix_shader to drive different colors for the flakes. For example, you could make the flakes metallic and the other parts glass by mixing them together using a mix_shader.

You can use the mix_shader to mix multiple flakes shaders together with different density and normal_randomize values. In the car paint example below, a second flakes shader has been used to create brighter flakes that are visible around the highlight.
