Metal Flake

Concept

This metal flake shader uses an angle-based color lerp effect to create extra depth and color intensity, alongside realistic dust particle simulation covering the top of the object.

Angle color lerp

This material has two color attributes that are lerped between depending on the angle from which you look at the object.

Flaking

Through the use of a few layers of roughness masks this material looks like it is covered in fine dust, creating the well known metal flake effect.

Colors and textures

All layers can be recolored, meaning that this material can easily be re-used for other effects in combination with different textures.

Optimizations

There is a feature switch allowing users to disable to color lerp or metal flakes on demand.

Not my textures

Disclaimer: I only made the shader. I did not make the textures.
