IOR / Index of Refraction List For Common Materials [For Use In 3D Materials / Rendering]

IOR, or “Index of Refraction.” You might’ve heard these words being thrown around if you’ve ever looked at a metal or glass shader tutorial.

But what is it really?

It’s hard to find a simple answer to explain what it’s all about, so I’ll be changing that in this article and explaining what exactly IOR is, why it’s important, how you use it, and lay out some common IOR values for materials so that you can use them in your 3D Application and Renderer of choice.

What's the Best 3D Render Engine (GPU & CPU) for your Needs?

“What is the best 3D render engine?” The question that pretty much every 3D artist has asked at least once. And with good reason.

You spend hours inside the viewport modeling, sculpting, texturing, and shaping your perfect creation—do you just leave it at that? Of course not.

You didn’t do all of that work for it to just sit in that dull gray viewport and be nothing.

No, you want that magnificent creation to shine in all its highly detailed, immaculately shaded, ray- & path-traced glory!

Normal vs Displacement vs Bump Maps: Differences and when to use which

You might’ve heard the words “normal map” or “bump map” or any assortment of other weirdly named “maps” when you’ve been scouring the internet for texture maps.

These maps sometimes trip up even experienced artists. So in this article, I’m going to explain to you exactly what these maps are and how you can use them.

What Are These “Maps”?

Sadly, these aren’t maps that’ll lead you to treasure, but they can sure lead you to better renders.
