This 3D texture shader generates random flakes. This pattern is used, for example, to generate micro-shading details in Car Paint.
→ Scale
Defines the size of the scales.
→ Randomness
How randomly distributed are the scales.
→ Density
Defines the proportion of the plane covered by flakes. A 0.5 density means that 50% of the surface is covered by flakes, the other 50% produces no flakes (empty).
→ Layers
On how may layers are the flakes distributed. Top layers hide bottom layers.
