Adding 3 glass shader on top of each other isn't physical. You have three channels for R, G, and B and adding them together is physical. But these colors are just for refraction and reflection is still white. Adding three whites means if reflection bsdf recieves 1watt, it reflects 3 watts.
Omg, you are absolutely right. That is brilliant, thanks! I will make an update. I have some questions about it, because you have pointed out very interesting thing. Can I contact you on messenger or somewhere else? This is my facebook: facebook.com/cg.vertex.73
This is absolutely incredible!! Brilliant glass shader with so many useful options to achieve the perfect level of realism. Thank you for this fantastic gift to the Blender community!!
Oh, thanks. 😁 Yes, a little easter egg there! 😂 It is actually quite an interesting stuff because I was wondering how can I do it with modifiers, so what you can see is made in 20 minutes and has 73 vertices.
Sorry if this is nitpicky, but from what I understand after reading some stuff regarding abbe's number on some IOR data sets, I learned that blue light disperses a little bit more than red light - that is, the difference between the blue IOR should be slightly larger than the difference between the red IOR due to the actual wave length of various light colors. Of course, for the best dispersion you would have to create a total rainbow gradient and not JUST limit the dispersion to red, green, and blue but that does work well and most people won't notice, however the clear delineation between R, G, and B will become more evident as you increase your dispersion amount. I actually was never able to solve this myself - how to use a rainbow ramp to get even, smooth dispersion. I chalk that up to my inexperience with the node editor.
I appreciate this and don't worry, there is nothing wrong about this type of nitpicking! 😁You are absolutely right and to be honest I am now working on how to improve the dispersion. Your comment inspired me to do so! 😀 Honestly, what I've done in the video is completely wrong for so many reasons. Just adding glass BSDF on top of another is basically wrong for dispersion. If I make something that I will be satisfied with I will definitely post it on my Facebook and make a video about it, but if you have some ideas let me know. It's quite a difficult task for me. Ones more thanks for the comment! This type of feedback is very nice.😁
I know you said that there isn't a point to using it for cycles but hear me out, it would be nice have a physically based cycles shader output and eevee one that could be used with the same settings so we could use eevee for lookdev and cycles for a physically based final render
Thanks for this great node! But I Can't figure out how to reduce noise, trying to make wine glass, under the bottom part of the glass i get a lot of noise( If I import my glass model to your sample scene, all is fine. I found it), choose Alpha Blend instead of hashed, still looks great in my scene!)
I am a bеginner and just finished watching your video and wanted to ask. I know that video was uploaded a long time ago.. but.. i want to make glowing object inside a glass sphere, how do you think this will work?
Well, I was wondering if it is possible to do that with modifiers and the result is quite interesting, because it is like 73 vertices or something like that and the rest are just modifiers. But what should I do with it, so I put it into a video about glass. 😂
Great tut! Following you from Cuba. Thanks for sharing, was very usefull , but when i downloaded the blend file from Blend Swap , i didn't found the group glass 2.0 in the nodes at the shader editor. Seems to be just a file with the default cube scene. Can you help me?
Thank you! I've just tried to download the file, and everything seems to work. The node group is currently called Glass 2.3. After opening the blend file you should see two glass objects. Maybe try to download it agin. If that still doesn't work, I can send it to you in another way.
@@cgvertex hey, thanks for the help , after downloading for the fifth time i cuold actually se the entire scene with the objects and group nodes, thanks a lot, i wish one day i can help you as you helped all of us with this shader . From Cuba many LOVE♥️♥️♥️
I followed this tutorial and found that mixing a transparent node with the finished glass shader is kind of limited. In your example, it indeed allows you to see a transparent material behind another, but if you were to switch the square "glass" panel for a sphere, you'll notice that it indeed shows the object behind it, but it is not refracted as it should, following the sphere's geometry. Have you found a fix for it? - I can provide pictures of this issue on twitter if you have one.
Me looks at the video " Eevee is not physically accurate when creating Glass because of so many limitation " Me looking back at my laptop who are on the verge on dying while rendering in eevee : "Iam sorry for sacrificing you for nothing "
Amazing work, didn't think it was possible to do such thing with EEVEE. But I can't see any dispersion. Screen Space Reflection is on EEVEE settings and material, blend mode and shadow mode are both "Alpha hashed". I've played with all settings of the node but defintily no dispersion. What am I doing wrong ? Thanks for this shader, you rock so hard
Hi. Thanks! 😁 What you are describing is probably a problem with high IOR. I am working on a way how to make the dispersion way better but now it is limited to the IOR. You have probably set it very high. Try to set it to like 1.45 and then slowly magnify it. You should see the dispersion.
@@cgvertex Thanks for your answer and indeed you're absolutly right, I should have think of that in the first place. This was a too high IOR. With a regular (!) value it works like a charm. Thanks again and keep your stunning work it's a pleasue to see how people can twist eevee in all directions and make it better each day because of guys like you
Hey! Do you know if it's possible to shift the pixels of screen with a black and white texture applied to an object? I've been trying to find a solution for a while without using the compositor
Hi 😁 I'm not sure I understand what you're asking for, but I can try to help. If you don't want to write here, you can write me a message on my Facebook.

I missed something, downloaded a blend file from you link- how do I save the material so that it is always available? I ask because you opened a material file you had saved. Thanks for any help in this.
I appended the material from the glass 2 blend file and then saved it as the default scene. But it's a quite silly way to do that. Take a look at the Material Library add-on that comes with blender. Asset management for blender will soon be available, but the material library add-on should work just fine.
Hi! Thank you for sharing this with us :) I believe that I am the only one here that don't know how to import shaders for Cycles (I am new in Blender). I have done everything the same as you are for the Evee shader and it work great, but when I try to do the same for Cycles shaders I can't find them in "Add". Sorry to bother you with this, but can you tell me how can I import Cycles shaders?
Hi. I have a simple method for you. If you need to get specific material from one blendfile to another, just copy the object with that material and paste it into your scene. The material is copied with the object, so you can now get rid of it and the material stays in your scene. You can then apply this material to any object. I hope this helps. I can bother you with the append and materials and node trees and so on, but to be honest, I personally do it as I described. It is just faster.
Absolutely agree, if you want physically accurate caustics, something like Luxcore or Appleseed is a much better choice. I was just curious if I can achieve something slightly similar with real time eevee.
Well, it can be anything. Check the normals of your object, make sure you enable all Eevee settings and load an environmental HDR image. If the problem still remains we can solve it privately via Facebook or whatever you want. Also check that the node group has the same values as the one in the file you downloaded.
thanks for the tutorial, the only feedback i have is that your editing is a little disorienting. Re the diffusion method, where is this in relation to the rest of the shader?
Hey uhm, so apparently my pc crashes when I try to use the node(glass 2.0) after I grouped it, the file is reletively low in size, when I try to switch to viewport shading,it crashes 😭
Yeah, for some reason it seems to be quite heavy in the new blender updates. I may try to optimize it a bit or try to do a lighter version with some basic functionalities.
All the options of the node group work very well, but when I try to change the color of the glass in the color option, it only adds a strange color reflection but the color of the glass does not change, that parameter I have to change inside the groups node ?
@@cgvertex Thanks for your answer, when I lowered the IOR value to 1.45 (the value original when I opened it was 30) it gave me a whitish crystal with very little transparency, I was able to change the color but it loses a lot of transparency and reflection, I think it would be easier if I could send you an image to an email, thanks for trying to help me

@@cgvertex sorry that I didn't reply. I don't know why youtube doesn't notify me for comments
Rather than Add use two mix shaders, first glass Red & Green with a factor of 0.5 then mix blue with a factor of 0.333_
Eevee is not realistic ;)
This is absolutely incredible!! Brilliant glass shader with so many useful options to achieve the perfect level of realism. Thank you for this fantastic gift to the Blender community!!
My guru didn’t tell me to make my chair out of glass.... but I caaaan use it for my donut and coffee 😏
Thank you so much!! I'm a digital nomad using an MacBook Air with the M1 chip so using Eevee helps me a ton!
Rarely do I ever just randomly come across something so convenient that subscribing is a no brainer. Thanks a bunch
cant thank you enough man! This is the most detailed tut ive seen about eevee nodes/materials. THANKS!!

You are a god for all Eevee users and we will protect you at all cost.
Yeah, I hear you up here! 😀 It is very kind of you. Thanks! 😁
Great video overall mate, a good looking glass shader and top notch explanation.
Dude this is literally the best eevee glass shader..(works soo well)keep up the good work and thank u vm
How do I install it?
I was waiting for this for a while. Beautiful.
Yes, it took much longer to make than I expected. I'm glad you like it! 😁
Thanks. Most vids use Principled BSDF and I had no clue how to use it in my toon shader.
You're the best, please keep doing videos. You focused on something everyone need
This is seriously one of the most impressive nodes ive ever seen in eevee. Insanely great job man, subscribed
