metallic
A value that you set to control whether the material has a metallic look.
Declaration
var metallic: MaterialScalarParameter { get set }Discussion
This property defines whether a material is dielectric (0.0) or a metallic (1.0). Although this property can be set to any value between 0 and 1, to create a realistic material, set it to either 0 or 1.).
- Dielectric materials
These are materials that simulate real-world materials that are poor conductors. In these materials, light travels into the surface of the material and the color is mostly controlled by the color of the sub-surface. Typical examples of dielectric materaisl include organic materials, plastics, and industrial minerals such as sand, limestone, marble, clay and salt.
- Metallic
A metallic (or conductive) material reflects light differently than dielectric ones. The overall color is caused by an immediate re-emission of the light from the entity’s surface. Typical examples of metallic materials include aluminum, chassis metal, chromium, copper, gold, silver, and titanium
