Chrome
Use the Chrome material type for all kinds of chromic and metallic materials. When more control about scale and orientation of the surface structure is required, use brushed metal, instead. Metal type presets are available within the Properties Editor.
Chrome Material
Reflection Color - Sets the chrome reflection color. When the chrome reflection is colored, reflected objects are also colored. The higher the brightness the higher the reflection on the surface. Black means no reflection; white gives full reflection. Click the color field on the right to open the color chooser; when the chrome reflection is colored, reflected objects are also colored.
Contrast - Sets the sharpness of reflections. Increase contrast with multiple reflections to draw out more detail.
Saturation - Affects the specular reflection. The higher the saturation, the less the specular reflection.
Metal Type - Sets the metal types used, changing the characteristics of the metal. These metal types are available: Highly Reflective, Aluminum, Amorphous Carbon, Silver, Gold, Cobalt, Copper, Chromium, Lithium, Mercury, Nickel, Potassium, Platinum, Iridium, Silicon, Amorphous Silicon, Sodium, Rhodium, Tungsten, Vanadium, and Iron.
Roughness - Activates/Deactivates the roughness of the material and controls the sharpness of the glossy reflections. The higher the value, the rougher the microscopic structure of the surface and more diffuse the reflections. Use Roughness must be enabled.
