In the process of modelling the last couple of cars I’ve made, one thing I’ve really focused on is creating a realistic, physically accurate metallic paint shader to bring my renders to a new level of realism. Finally I think I’ve achieved something worth while that looks good, is physically accurate, easily controllable and works well even at low samples both up close and from afar.
The node setup for the paint itself is quite simple, comprising of a total of four nodes.
The first render shows a simple scene with a HDRi and a sun lamp. The two left spheres both use the same main coat, however the left most sphere has a silver undercoat whilst the 2nd sphere uses a golden undercoat. The third purple sphere has a dark purple main coat with brighter flakes and uses a silver undercoat. The fourth green sphere still uses a silver undercoat and a brighter top coat however it has a candy effect which darkens as the angle between the paint and the camera increases. The render is at the resolution 2000*800 with 300 samples. The only post-processing done was RGB curves to bring out the highlights.
This render shows the material in the context of a car, showing close up detail even when using low samples (32 in this case)
I was wondering if anyone has any interest in a material such as this?
