IOR to Reflectance |
- Where to find it:
- Add Adjustment Layer / Extension Pack / Specular /
- NodeGraph / Right Mouse Click / Nodes / Filter / Extension Pack / Specular /
IOR to Reflectance will convert an IOR value to a Surface Reflectance Value.
For example an IOR or 1.5 equals a reflectance value of 0.04 or 4% reflectance.
This can be useful if you are working with specular reflectance maps in your shaders and only
have access to a surface's IOR Value (for example from various Internet resources such as https://refractiveindex.info)

When the Manual Input option of the node is disabled you can feed in values from other layers or nodes
that will then be converted.
