Index of Refraction values (IOR)
To create realistic PBR Materials for use in 3D Applications you will need the right Fresnel or IOR Factor in order to achieve a more accurate representation of a surface material. These values are are used in many 3D applications like Blender, Cinema 4D, Maya, 3DS Max and so on.
Here is my list of commonly used materials which I use in my daily 3D life 😉
IOR List – Commonly used materials

Please be aware that these values are approximations for use in 3D applications and not for scientific use!
If you have more IOR values you find useful, just leave me a comment below and I will insert them into the list.
