Web1 feb. 2015 · As a general guideline, here are the Reflect IOR values for some common object types: water 1.33. plastic 1.45. glass 1.5-1.8. diamond 2.4. compound materials like wood, stone, concrete etc 3-6. metals 20-100. I know that in vray the Fresnel IOR and IOR are linked. I believe that the Fresnel IOR is actually locked by default. WebThe index of refraction is a formula used to calculate the exact change of direction for a beam of light based on the material of the second medium (which is normally the 3D object in Blender). Below is the formula used to calculate the index of refraction for a given material. IOR Formula In this formula, we have the following variables…

Plus I found the IOR of clear … WebMany materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion.Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength (λ) of 589 nanometers. There are also weaker dependencies on temperature, pressure/stress, etc., … how far do humpback whales migrate
