WebSpecularity refers to the amount of specular light reflected by a surface. This value is inherent to the Material type, and usually the default value of 0.5 is accurate. The Specular input is not used for reflection/specularity maps or to add surface variation. These should be handled in the Roughness map. Metallic Webwater: ior = 1.33, specular = 0.25; glass: ior = 1.5, specular = 0.5; diamond: ior = 2.417, specular = 2.15; Since materials with reflectivity above 8% do exist, the field allows values above 1. Specular Tint. Tints the facing specular reflection using the base color, while glancing reflection remains white.

Essentially, the IOR value is used to determine how much the ray will be bent when it passes through one medium to another. For example, water has an IOR of 1.33, whereas plate glass has an IOR of 1.52. incarnation\\u0027s 1t
