IOR / Index of Refraction List

Index of Refraction values IOR – For use with 3d modeling / rendering and animation applications, Over the past few years I have been collecting IOR Index of Refraction values I can find for use in 3d rendering applications, Many 3d applications these days allow you to input actual IOR values in order to achieve a more accurate representation of surfaces during rendering of your 3d models,

RGB IOR values for common metals – Chris Hindefjord

These IOR values are taken from the great resource RefractiveIndex,INFO, but it only includes the values relevant for setting up materials for physically based rendering, The values listed here should work with several different rendering engines, such as Octane Render and Arnold, RGB IOR Values for metals; Red 650nm Green 550nm Blue 450nm Aluminium Al n= 1,34560: 0,96521: 0,61722: k

Fresnel IOR

I know that in vray the Fresnel IOR and IOR are linked, I believe that the Fresnel IOR is actually locked by default, My thing is which one to use,? Later in the guide it says: Index of Refraction has been calculated for many materials, so you don’t need to guess, You can find various IOR tables on the internet, Here is one of them: Steel 2,50

I see how this can be confusing and while I always recomend Viscorbel’s great tutorials, he’s including this info without really understanding it mSo what your saying and from the article, I should not use Fresnal IOR and IOR for metal materials at all? Also for other materials, I should leaveVray uses the IOR driven fresnel effect for both reflection and refraction, but each only aplies to its property so either reflection or refractionhmm i was wondering what the IOR of moss was the other day most useful!Hi Jojo, I totally agree with all Juray wrotes if I may I would add some tought about :- Actually if you create a plastic material, you can simThank you very much for your excellent explanation, How do you know when to change the Fresnel IOR from 1,6? Do you have some guiding values for arThere are many lists online, Lots of them don’t really offer the every day materials that one would hope to see, but instead they consist of chemicJust keep it 1,6 for everything except metals, Most non-conductor but really, for CGI purpose, just non-metals, have extremely little front angle

Material IOR Value reference

Incorrect! If you have your IOR and Fresnel set, you can have alpha at 1 and you’ll still get transparent renders… don’t believe me, try it out, Both the glass IOR 1,53 and the water 1,333 are set as solid as the slider goes, 1,0, it’s the nature of the beast, This is Blender internal, btw, …

Understanding metalness

As we mentioned before, the IOR still plays an important role when creating a physically based material, Therefore, we still need to consider this as part of the shader, In fact, the site RefractiveIndex,info is a great resource for understanding the proper IOR of different materials, However, inputting those numbers into a V-Ray shader will
