Eevee & Cycles Car Paint Shader
This Blender 3D shader works in both render engines, Eevee and Cycles. There are barely any noticeable differences at all. It's free!
Overall color setting
Just select a color of choice. This color will change the overall look of the reflective flakes. These have the most significant impact on the look and feel.
When making changes to this color (usually clear coat is white ;) ), you can add additional color effects to the clear-coat itself.
Base Color & Base Color Effect
The upper color adds a diffuse base color while the lower color will add color only visible are specific viewing angles.
I hope you'll find this shader useful. I had tons of fun creating it.
