I compared this with a 1 minute tutorial and yeah it's worth every second to put in the effort to include dispersion.

Instead of me adding all those nodes and since glass is basically glass everywhere on planet Earth, I wonder is there a way to download your glass setup? The basic glass node just looks like chrome reflecting the environment with no real transparency. Maybe someone has this online somewhere if you don't. very nice results.

No, this setup pretty much works for all use cases Just make sure that your solid object doesnt intersect with the glass itself since that will always create weird results, no matter what shader you use

Should the Math node to the red Refraction BSDF node use the Subtract function and Add for the blue? In the video you are using Add for the red and Subtract for the blue. I ask because you had 1.4 set as the red IDR and 1.5 for the blue. Maybe I'm not understanding how the Math node works.

Thank you so much for this tutorial. It is a very nice shader. But please note at the end the math nodes feeding the Refraction BSDF IOR values are wrong... the red IOR should be set to subtract (not add) and the blue IOR set to add (not subtract) because in glass/crystal/ice the red IOR is lowest and the blue IOR is highest.

@philipkriegel

Жыл бұрын

Hey there! Thanks for trying to improve the shader, but what you are talking about is the wavelength of the light that is going through the medium. You're right, red is lower than blue on that scale, but the index of refraction (IOR) has nothing to do with that fact. The way the colors are produced are controlled by the shape and physical attributes of the object, more than light wavelength itself, which is why sometimes you get disperion that is yellow and purple, rather than red and blue. So really, which way you plug it is personal preference and won't change the outcome too much, especially not the physical correctness of the shader, so don't worry :D But you can of course do it your way, just make sure not to mix up those 2 things, since they are somewhat connected, but not in the way that you think they are

with blender 3.4 for some reason my caustics turn only red or green or blue depending on what color I'm adding first. Can't understand if it's a bug or i'm doing something wrong

That really depends on the scene and your other settings. I find about 1024 samples for a still image to be enough for the denoiser at 4k resolution When rendering glass, I always set my glossy rays to 32 at least :) Can you tell me the resolution you're working with? It really matters, because the higher it is the more information the denoising algorithm gets, so that can help you a lot. Try doubling your resolution and then devide the amount of samples by 4 That should give you the same render time, but better results :)

It helps, but generally, even in engones like luxcore or octane, enabling dispersion tends to bump up render times and generally make the glass noisier So really, try to fiddle around until it sticks As I said, doubling the resolution and dividing the samples by 4 always seems to do it for me, in the end, you can always just resize the image down to what you needed originally :)

@philipkriegel

I rarely use Eevee to be honest. Most of the stuff I do is done in Cycles. I like experimenting with nodes and that isn't always very intuitive with Eevee. Of course eevee is a lot faster and can get good looking results, but it's simply not worth it for me to trade years of experience over fiddling with eevee until I just kinda get what I wanted. But I think unreal engine has quite good looking glass right now, and character shading is also really nice. Over all, I like Cycles because it's simple and it just works 100% of the time But of course, someone who is more imvested in eevee could get production grade value out of eevee, it's just that I don't know how and never got invested in learning it

It's a little hard to explain via text, there are a few tutorials on that sort of glass online, but here are some basics: - import a circle with 8 vertices - subdivide the edges so you get a vertex in the middle of each edge and bevel them so they are close to the initial vertices of the octagon - extrude upwards to the height of three octagonal part of your mesh, then do it once more to the height of your indents on the top - use the loop tools add-on (circle option) to make it perfectly round and extrude to get the rest of the glass and you're basically done Note that I am not a good author so you are probably best off watching a tutorial either way, because my written explanations tend to leave more questions than answers behind :)

If you're talking about the advanced glass shader from the viseo I made a while back, it's actually pretty easy You just need to add another add shader and place it all the way in the back, connect the red refraction node to it and then create another refraction node, make it white and place it in the top input of the add shader :) Make sure to tweak the brightest of your other colored refraction nodes so the glass isn't too bright and you're good to go, you can do that by eye, just make sure they all have the same brigthness

Hey Jack, So basically every bsdf node in blender resembles a basic physical property shown in real life objects, be it the ability to refract light, reflect it, scatter it uppon impact etc... So what do in blender is more or less analyze what an object looks like, see which traits it has and then we try to recreate it using the same properties in blender. For instance for paper, you could use a diffuse BSDF + glossy BSDF + subsurface scattering, combine them using mix shaders and a fresnel node and then you just adjust the values until they fit You up the rougness for instance on the glossy node so it's less shiny and increase the subsurface scattering so light shines through it (also would work with a translucent BSDF node) So by that logic, it's easy to assume, that glass is just a refraction BSDF + glossy shader because because it only refracts and reflects light They share the same indeed of refraction because that is the only thing that is physically plausible This is basically how we used to do all of the our shading before blender 2.79b (when the principled BSDF got implemented) A lot of it is just thinking about the basic function of a material, but there is also some learning by doing + trial and error involved As far as I know there is no real documentation on that subject, but I also didn't check in great detail, should you need anything, I'll always be glad to help though!

anyone reading: if the glass looks broken and glitched out in cycles mode check if theres mistakes in the faces duplicating etc

Yes, the thickness of the glass is just as important in 3D as it is in reality.
