We will cover the car’s steering wheel with a light lacquer color. And we won’t even need to reach very far into our bag of tricks to do so. We’ll start by defining an ivory color in the Color channel. Alternatively you also use a Fresnel shader as a texture to add color variation from the center of the steering wheel to the edges. Set the left end of the gradient scale to white and define the warmer ivory color at the right end.
Lacquer needs to have a smooth, polished surface and must therefore also have reflective properties. Rename the layer Default Specular to Reflection and set its mix mode to Normal. Set the layer type to Beckmann. This type can generate sharper highlights than the GGX type. Set Attenuation to Additive so the reflectivity lies over the color, which prevents a reduction of color or reflectivity. To avoid the highlights being minimized we have to add a certain degree of Roughness, even to surfaces that are actually smooth. Set Roughness to 20%, Reflection Strength to 70% and Specular Strength to 100%.
In the Layer Fresnel menu, set Fresnel to Dielectric and Preset to Glass. Glass is the option that comes closest to looking like lacquer. Now drag the material onto the Null object Steering (Lacquer object group) in the Object Manager. We don’t need to define a Projection type since the material does not contain any patterns or bitmap images.
