Is there a description about how IOR vs Specular works for non-metals?

Hey Michael,

there is nothing (afaik) from our side, however there are many great online sources that explain the topic thoroughly.

As for us, we implemented it so that it is possible to use both Fresnel IOR maps as well as Specular maps. There is some internal formula that calculates Specular off of IOR and vice-versa (0.5 Specular == 1.5 IOR).

I hope this is enough (I am not a scholar on the subject),

Something like this may contain closer information: https://www.programmersought.com/article/9101852439/ , if that's what you desire

Thx.
After scrolling through the article and feeling smaller with every page, I decided to stick with the IOR setting (where I can pretend to understand what it does) before I shrunk too much to reach the mouse on my desktop.
