Adjusting Refractions with Index of Refraction<br />
IOR (Index of Refraction) is used to calculate among of the light refracted from transparent object.<br />
The newly added IOR default is set to 1.55. Please see the chart <strong>for</strong> typical objects' IOR value.<br />

Default set the Refraction IOR to 1.55; please refer to images below <strong>for</strong> setting of IOR to create<br />
desire material.<br />
Please note that reflection and refraction IOR values are separate, but to achieve an accurate<br />
effect these values should be the same<br />
