This must be an April Fool's joke, right? However, thank you, I really appreciate it. And you can be sure that I will continue! You should know that there would be no CG Vertex without you. So thanks. P.S. Don't watch my previous videos, I shamelessly used the same music as you. P.P.S. I don't regret it!

@@cgvertex no its true. excellent shader breakdown.

CG Vertex and Default Cube ma men be ruling!

You jinxed it cube he disappeared

and he stopped

How did it go? Did it go as well as illustrated or were you not able to get it to work? I have heard other people couldn’t get it to work and im paranoid that i am waisting my time if i try to attempt this

Sorry its just how i go i prob know its not that bad but still hearing from you would be good assurance

Thank you! To be fair, the three shader method is still much faster, unless you use eevee.

This sounds amazing.... is there any image you can show to see the difference in this method? also have you achieved this more realistic dispersion for evee. Tell me more this is an exelent coment

If only there was the ability to adjust samples for individual types materials ( like there was for light bounces)

Fabulous !

Or why use a colour ramp at all? Why not use Combine HSV and synthesize the components yourself?

this was covered in the video

@@bank8489 In the video, he uses RGB colors spread out with black points at the end. My method does this procedurally, which gives you a more uniform distribution of all colors instead of just RGB and colors that are linearly interpolated between those 3

@@xXWhatzUpH8erzXx yeah but didnt he show the technique you describe toward the beginning

I got that too and found that I had plugged in "color" instead of "value" on the white noise texture

And is that a good thing?

@@cgvertex This thing is more than good, this is great. Love the effort

Thanks! Well the laser light was tricky, and it is not really a laser but it works ok. The node setup for the light is included in the blendfile if you want to play with it. The material is called Material. 🤦‍♂️

I quite like your videos BTW. Keep it up!

Thanks! No, I didn't compare them, but at 1:00 you can see how fast is Luxcore in the viewport. I believe you can get a nice dispersion with luxcore is a matter of minutes.

Priceless !! Can you make this tutorial work with Blender 3.1.x on Linux?

but then the edges are not black (there will be red twice) :(

Thank you. Unfortunately it's way slower than normal glass.

Also i first followed the first method you showed, i saw this on a CG Cookie tutorial. For funky result i added a Hue/Saturation node, on each glass/refraction bsdf, with the respective colors. Then i connected a value on all the Hue sliders. Changing the value gave me some really cool results :)

I guess cycles is quite similar to Arnold in certain ways. I've just tried rendering the scene in a volume, and it doesn't seem to work that well. What's important to understand, and I feel like I did not emphasize it enough, is that this is the most "accurate" way that I could find of faking glass dispersion. However, there are other, computationally cheaper ways of faking it. It might not behave as "accurately" as this one, but it looks just as good. If I may be a bit more technical, the shader in the video is taking advantage of something that is known as fireflies. It is a defect produced by cycles-like engines. When we try to render something like a glass dispersion in such engine the fireflies (very bright spots) look like defects, but If we were to let the engine run for a while, and I mean for an unreasonably long, these defects would form a vague illusion of caustics. That's what I'm doing in the shader. It is not efficient at all, but it works, and it should behave somewhat like in reality. The volume just adds complexity to it. The fireflies, which will eventually form the dispersive caustics, are now not only on the floor but scattered everywhere in the volume, which makes the image even more noisy and hard to process. There are engines like Appleseed and Luxcore, which are designed to render caustics dispersion really fast and extremely accurately. As I said, there are other ways of faking this effect and getting much faster results. Many people have made such shaders, but they put it on sale, so it is hard to guess how they work. I may try to do something more efficient myself at some point, people really seem to be interested in that. Sorry for such a long response, but I really wanted to cover everything. I'm not really familiar with Arnold, so these are just general concepts.

@@cgvertex oooh i see, thank you very much for the detailed explanation! I will look more into other engines, this has just been a fun side project but I've been learning a lot from it. I would absolutely watch another video from you about this haha

Thank you! Do you mean literally the object or NFTs and Ethereum in general?

@@cgvertex yes object itself 😍

Well, it was quite simple to model so I won't make a tutorial about it. But you can easily find some models of Ethereum logo online.

@@cgvertex thank you sir !! will do that 👍

Hi, I just downloaded blender 4.1 and opened the blender file from gumroad. Everything seems to be working fine. Where exactly did you run into the problem?

Thanks! As far as I know, luxcore does not currently support blender 3. But I think it's just a matter of time.

I don't know how is it in general but when talking about glass, LuxCore is like million times faster and more accurate. Doesn't mean it's better in general though.

Thanks! I usually just imagine what I want to create and then look for a way to achieve it. Trial and error plays a huge role in this process.

I'll check it out. This was more of a proof of concept, but I'd like to make an optimized version in the future.

if you slowed down the video you can see he typed "Math" in the search bar, you can find it then.
