f0 to IOR online calculator?
Hello Everybody! so I have been learning a lot about PBR materials and their uses, and that f0 and IOR is one of the essential things to achieve a realistic effect on materials. so I have figured out how to obtain f0 values from IOR online but have not found easy f0 from IOR calculators. some calculators give the IOR to f0… -
3d coat how to input measured IOR values?
so I am using 3d coat for a material study and i need to use measured IOR levels but I don't know how to input those values, for example I have a gold coin and the measured value for gold is 0.470 . Do I input 47% into the metelness value? that dos not seem right what do i do? -
IonBlaster 2.0
Hey Guys! :) I was browsing trough my old files a couple of days ago, and I happen to stumble over some old work. It was my idea of an Ion-Canon (Star Wars); if it was made in modern time... I have been looking for a "firsttime" project for the new Pbr method, so I have remade the textures for this one. :) Nothing fancy… -
SOLVED: IOR map
Guys, I outputed an IOR map from DDO, and obviously it's giving me a map from 0 to 1, with values around 0.1 and 0.4. Does anyone know how to interpret this map? Arnold shaders reads an IOR like 1.0, 1.33, 1.4, 2.2, like proper refraction index. How can I map this map to my shader? Is it like a Fresnel value? Percentage of… -
Where to find IoR value in https://refractiveindex.info/
I've been looking at this site for IoR value for some time. But everytime I get on this site it confuses me. Some element seems right some doesn't. Eg, plastics(under shelf 3D, book plastics). it says reflractive index n=1.48. I assume 1.48 is the IoR. I put it into some render engine like vray/mental ray. It seems giving… -
Game engines and IOR
Hey guys, I have a question concerning the use of IOR on games. We know that one of the key points on making a believable material is adjusting the IOR value, specially when talking about metal and glass. I know that there are ways to change the IOR value of your metal on engines like UE4 and unity, but my questions is: Is… -

PBR IOR Setting for Wet Surfaces
When needing specularity on a mesh, I suppose depending on your render you use, you may be using PBR reflect, what was surprising to me, as I'm use to the old workflow, although understanding PBR probably won't take me long is; index of refraction plays a role when attempting to give a material specularity, whether to make… -
metalness vs IOR
Hi. I am sorry if this topic appears again but i am still confused about the metalness workflow and was wondering if someone could help me out and shed some light on it :) Lets take the IOR first. First of all i am confused by all those different IOR lists excisting online. If I take "Iron" for example, I can find totally… -
PBR material reflectance / IOR / fresnel database? + question about sRGB and Linear interpretations
Hello artists, I'm reading the book "The PBR Guide" by Wes McDermott. In the book, Wes explains the importance of finding the right physically accurate values for settings such as reflectance/specularity, IOR and Fresnel. Is there a good resource or image that might list various materials (metals to dielectrics) and their…
