IOR List for PBR Materials

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 😉
