Thank you, I'm glad you liked it :D

Steve for the win! Thanks, I'm glad you enjoy the pace, I always hated it when people rushed a tutorial, I think learning takes tame and understanding :D

#AbsorbtionSteve! I'm glad you liked it :D

Thank you! I'm glad you liked it :)

Gerne! Danke für's Feedback :D

I'm glad you enjoyed the tutorial :D

It also helps alot that you are explains the physics and the wayworking of each nodes also! Thank you so much fo the tut and keep up the awesome work!!!

I'm glad you liked it!

@@philipkriegel Would love to know how to extend these refractions into the shadows (like how like goes through cut glass) Is that an easy adjustment to the shadow ray?

I have a tutorial on custom caustics which is probably what you are looking for, feel free to check it out, it's fairly easy to do once you see the setup!

@@philipkriegel On my way!

Gerne :)

You're welcome! The average IOR for diamons is 2.418 Make sure to change that from the standard 1.45 to get the best results :)

@@philipkriegel ya i surely will, thanks!

I don't plan on making any lighting tutorials since I need to still become better at it myself, but once I'm on a more confident level, I'll cover that as well :D

I'm glad you liked it :D

@@philipkriegel amazing work man! keep em coming!

Immer gerne, Kasbär! :D

@@philipkriegel Du bist ja ein Glas Experte. Hättest du Mal Lust ein Video zu machen, wie man "antique Glas" in blender machen kann ? Also mit der schönen Reflexion? Ich habe mich gestern dumm und dämlich herumprobiert.

Das macht so gut wie keinen Unterschied wie alt das Glas ist. Wenn du Probleme mit der Spiegelung und der Lichtbrechung hast, dann liegt es vermutlich daran, dass dein IOR falsch eingestellt ist. Darauf ankommend aus welcher Zeit das Glas kommt, wurde vermutlich eine andere Form von Glas benutzt, die haben alle einen anderen Lichtbrechungsindex. Hier ist eine Seite auf der du viele verschiedene Optionen gelistet bekommst, unter der du bestimmt auch dein Wunschglas finden wirst: pixelandpoly.com/ior.html ansonsten, wenn du weiterhin Probleme damit haben solltest, kannst du mir gerne Privat auf Discord schreiben und mir die Datei senden an der du arbeitest, ich helfe dir gerne weiter :)

@@philipkriegel oh ja sehr gerne, wie ist denn dein discord Tag ? Ja ich meine mit antique Glas nicht unbedingt altes Glas. So heißt die Art von Glas. Kannst ja Mal googlen. Das Glas hat eine ähnliche Reflexion wie Wasser auf dem Meeresgrund.

Philip Kriegel#4553 Das ist der Tag kannst es mir gerne schicken, ich schaue es mir dann nach der Arbeit oder in meiner Pause an :) du findest aber auch meinen Discord Server in der Videobeschreibung

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

Yes! That's a cool idea and you could totally do that! :D

I'm glad you enjoyed it!

@@philipkriegel yes, light with transparent object is a hard topic. I saw that you got other videos about. So that's cool. Thanks for sharing

You're welcome :) if you need help with anything make sure to join the discord server linked in the description, we've got lots of members ready to help each other

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

It's not supposed to be dark, you either didn't connect something the way it's supposed to be, out you might be using Eevee

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 :)

I have the same issue. Switching to the OpenImageDenoiser on the Accurate setting seems to help.

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 :)

Do you mean something like this? ae01.alicdn.com/kf/Hbec9e8d8cde9456596fbf938844bfd64u.jpg_640x640Q90.jpg_.webp

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 :)

@@philipkriegel can you please make a tutorial of that? pleaseeeeee

I just posted it :D

What shadow issue? There is no issue with the shadows, perhaps you could explain the issue you're facing?

@@philipkriegel Casts a solid shadow.

Then perhaps you have not connected something right or you might be using Eevee, I have used this shader on multiple occasions, yet have never found it to showcase any specific issues, especially not regarding shadows

Sadly not, it is really hard to get good looking glass in Eevee I definitely have some shaders made that look better than the standard glass bsdf, but obviously when I make a tutorial, I want it to be as close to perfection as I can get it So you might have to wait a little for it but once I figure it out, it'll look really good :)

@@philipkriegel Ah! I am delighted and sad at the same time, but definitely understand the effort. It's true, eevee needs much more work for things to look good. The SSGI re-write for "eevee next" with 3.3 looks promising and I hope it'll make things easier. In any case, you are absolutely amazing and I can not wait to see what you'll do next! ^.^

I have recently been inspired by blenders native caustic system Since I wasn't really satisfied with the results I'm getting and the limitations, I chose to make my own node setup that will resolve the native limitations with shorter render times But I have yet to flesh out some minute errors before I can call it done, I'll upload it soon though

@@philipkriegel Sounds like you are experiencing quite a lot with blender (as one should). Very exciting times ahead then. One of the hardest difficulties in eevee, I find, is skin shading, shadows, and glass. If they ever manage to make that better, there's really no telling how far eevee will go in comparison.

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

Yeah I have one on my channel. It's the Pokal glass tutorial, you should be able to find it easily when scrolling through

@@philipkriegel Found it! Thank you!

Can you send me a screenshot on discord of what is happening? Also have you connected the gloss shader yet? Maybe your normals are inverted, try going to edit mode and selecting everything Then press shift+N and see if it is still like that

You use the same inputs as with the principled bsdf Roughness for rougness maps and normal for normal/bump maps

Thank you :)@@philipkriegel

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

@@philipkriegel Yes! It works! A bit difficult for a beginner, but I did it! Thank you so much!

You're welcome :D

What version is this blender?

@@philipkriegel unfortunately by doing this the caustic will no longer be affected by the absorption cloror, now I have a blue glass with a white caustic sigh

Hey there! Glad you liked it! I got that covered in here too :D kzfaq.info/get/bejne/hs5_oKWTzqmUpIE.html

@@philipkriegel I already found it! Thank You!

Hey there! Usually it works equally well on all meshes, perhaps you could send me your blend file on discord or via email so I could check what the issue is :)

@@philipkriegel Ок). Thanks!

Here's a video covering just that: kzfaq.info/get/bejne/edd5pchzmLy-XZ8.html

What texture do you want to bake?

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!

It's just the lighting from the HDRI. The texture you're referring to is just the background being refracted by the mesh, when rendering glass topology is really important for the final look of refractive objects.

@@philipkriegel Does the thickness of the glass in the model play a role like it would in reality? I think my glass a few mm too thick but not sure...

Yes, the thickness of the glass is just as important in 3D as it is in reality. When it comes to path teaching, the render engine tries to simulate reality as closely as possible with all of it's variables, so it's generally a good idea to stick to real world measurements when making a model so everything reflects and refracts as expected

Sure can, that's it: polyhaven.com/a/kiara_interior

@@philipkriegel thanks

Sure it's a lot, I wouldn't recommend making animations with this setup, but this is made for quality, not quantity

Check if your glass has a realistic size and if your scale is applied. Perhaps your dispersion is too high, try lowering that value to get a better suiting result

​@@philipkriegelokay I will check, I'm amazed by the fast answer!

@@philipkriegel It worked Thanks! I lowered dispersion to 0.010 and now its perfect. It might be too low but Im satisfied.

I'm not gonna say that blender is the easiest 3D program to use But it's definitely the easiest production-ready program Compared to autodesks alternative, blender is a breeze to learn :D
