WebI didn't realize the specular was tuned to 1.45, thanks for pointing that out! I found this formula for the principled shader. I am not sure if its correct but it appears to be in line with what said. Specular = ( ( IOR − 1 ) / ( IOR + 1 ) ) ² / 0.08. Thanks for the help u/sumofsines, I really appreciate it as always. 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 WebBui Tuong Phong (1942-1975) was a Vietnamese-born computer graphics pioneer that developed the first algorithm for simulating specular phenomenon. His model included components not only for specular lighting, but also diffuse and ambient lighting. Options ¶ Hardness Size of the specular highlight.

Web11 apr. 2024 · Change this to Specular for the best results. Diffuse transmission will, well, diffuse the light and not concentrate the rays into caustic patterns like we want. IOR is a balancing act with geometry and placement of the lights. In general, the lower the IOR, the less the light will bend, and the further away the focal point will be. WebThe index of refraction, or IOR, is an optical measurement that describes the change in the direction a light ray is traveling. 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.
