Hi! Very nice tutorial. I'm especially impressed by your approach to realism... even going so far as to explain the reasons for your modelling. This is something I found missing in so many - very good - tutorials and builds: things that _look_ good and real, but simply would work in the real world.
Hey there! I think that a good tutorial doesn't only consist of raw information about how to do something. You need to understand why you're doing something, so you can never do it wrong when trying out something new :) I'm glad you like my video and I am thankful for your comment ^^
I know why the model is red instead of blue. When you do ALT + E, it's to Extrude the faces (bring them outwards). When you did it, you place them inwards, so the entire thing was "inside out" :) You can see that if you enable face orientation *before* extruding the faces, it will be red if you place them inwards, and blue if you drag them outwards.
Just my thoughts exactly... I had a little laugh when he said he had "done this like 200 times over for this tutorial and it's always red" :) Maybe after let's say 100 times it would have been time to either 1. switch the face normals before extruding or 2. extrude outwards instead of inwards (okay, that's a problem if you modeled the outer shape of the glass) or 3. use a Solidify Modifier and apply it afterwards.
Guys I know why it happens But you'll have to understand that making tutorials is really hard, you gotta do things over and over again and remember every single step to make it as efficient as possible I generally record one and the same tutorial between 5 and 20 times until I feel it's good enough That usually ends up being something between 4h and 20h of work just to record it I just want people to know that stuff like that happens if you aren't careful about what you're doing and how to fix it, since it is a good learning experience
@@philipkriegel I totally understand that, my channel is nothing but tutorials lol :) I do the same thing. I just thought I would mention it because it sounded like you didn't know why it was happening every time
I've been using blender for about 6 years now I know why it happens, but I'm trying to have every single issue a person might have while recreating my stuff in my videos so they see how to fix them And people still surprise me sometimes on my server with problems that I never would've thought of
Thank you :) currently 96% of my active viewers aren't subscribed, which is odd to me, but what can you do :/ I'm glad if I can at least help others with what I do 😌
Great tutorial! In some parts though, you don’t say which mode you’re going into and tend to skip over the tiny details that matter. Was very confused but, managed to make a cup!
Ohh I'm sorry I thought saying it once or twice would be enough and later I must've gotten carried away I'm trying to make my videos understandable for new users and I'm glad you managed to finish it anyway If you have any questions about anything you can join my discord server, there I and other people will try to help you as a community :)
Hi. I watched a lot of tutorials about making glass in Blender, and You are the first one who talked about Volume Absorption node. I just only want to say Thank You for that :)
Great Tutorial, before this I cannot understand how it a glass material into Blender. I pursuit this for years! Now I known how it easy to make glasses! Thanks!
Perfect tutorial! Great explanation of how the glass settings work. I also like how you get a little bit into the render settngs > lights paths, not mentioning the modelling with the lip etc. Thank you!
Came for the orange juice, stayed for nice explanations and smooth music :D so learnt a nice glass cycles shader For anyone if principled volume density DOESN'T work, it can be because you didn't apply the scale (select obj CTRL + A, apply) BUT if density still doesn't works, it is probably, you are like me, designing things with real world sizes. I made a 3cm/10cm glass, so I tried density 200-420 and it works! Volume bounce 12 with 300 sampling.
Yes, that's exactly how it is Most BSDF nodes will be distorted or stretched if the scale of the object is not applied Also volume nodes won't give you realistic outputs if your object is too big or too small
If your size is of by a lot, it's simply not going to look realistic. You values will need to be bigger and therefore it will have a different look to it I suggest making things to scale whenever possible
Absolutely fantastic tutorial! I've been wanting some realistic looking glass, but more importantly, I've been wanting to make something called "depression glass." Specifically a color called "Ruby Red." I always thought that changing the base color made it look a bit weird, so the trick with volume absorption looks perfect! I had to crank the density way up to something like 2000, but it worked perfectly! And it makes perfect sense, because just like you said, the thickness of the glass will drive how that looks, which I can observe in real life when looking at my glass! Thank you, sir!
You are very welcome! Some objects will require you to use higher values, that is absolutely normal, especially when they are very thin. I'm glad you enjoyed the video :)
It is still by far one of the biggest glasses ever created. The scale is still in meters and you haven't really scaled it down.^^ Otherwise a great design, love it.
You're welcome :) The IOR is the index of refraction For the most realistic results, it should be set to 1.44-1.46 for glass and about 1.333 for liquids Having an IOR of 1 is like looking at air If you're unsure what the index of refraction is, I suggest you watch a video on it or read an article, as it's something every material has :)
@@philipkriegel Sorry to ask... Do you accept suggestions? It would be great to see how to make realistic bubbles in a colored liquid, especially when the bubbles are half above the surface. Almost all I can find on TH-cam is about animation not shaders. Thank you.
You can create a liquid like shown in the video with the volume nodes. After that you can add little spheres with a normal glass shader inside your liquid, that usually does the trick. There is sadly no other way to do it because those bubbles need to affect the volume of the liquid and there's currently no way to erase volume from an object without boolean, and that would pretty much destroy the mesh, so the sphere method is the best I could think of.
@@philipkriegel I think I've tried something similar, but the underwater part of the bubble was almost invisible, while the liquid surface inside the bubble was visible more than needed.. I've even tried boolean, with the very same result. Gonna try again at home.
Amazing tips about how to approach realism. I have a question. instead of Extrude Faces Along Normals for thickness can we use solidify modifier? what are the pro and cons?
Thanks for the tutorial on this topic. Regarding the lip on the edge, I don’t think it’s for safety. It’s just chipper in mass production. Expensive glasses often doesn’t have any lip or it is barely noticeable.
Expensive glasses like wine glasses also tend to not be used as often and are usually a lot easier to break It's a deliberate manufacturing decision which actually increases the production cost While for mass production mainstream glass, the lip offers more durability, expensive glassware like wine glasses use the lip to better distribute the liquid for a finer taste Glasses without a lip are usually cheaper and made out of more brittle glass You can read more about it on the internet if you are interested :D
I try to avoid creases because they don't add topology so you need a higher topology count to make them work Also you would want a little bit of roundong on the top of the liquid to showcase the surface tention, which in the end, doesn't add much, but at least in some cases, it'll show you a reflective line where the liquid ends. You should try to avoid creases unless you make film assets where even topology is important, or you do boolean operations without retopology afterwards
Hi, I've noticed should you Extrude along normals scaling outside the cylinder, rather than towards inside as in your example, face orientation of normals stays in blue color, no need to Shift+N to invert. However very clear explanation and useful. Bests TY TY TY BTW I just saw someone else already remarque same stuff. LOL
Thank you, Philip! Building my first glass object was a breeze with your input. One question, the color for Volume Absorption comes out inverted in Cycles Rendering. I can make it work but am wondering how to fix this. Any hints you can give? Edit: Turns out this must be some sort of bug. After restarting twice it works.
Thanks a lot, I'm always glad to hear that I'm helping people If that happens in the future, selecting the object and pressing control+A and then applying the scale should fix the issue If you scale the object and don't apply the scale, blender thinks that it has different dimensions and things get calculated differently
I already bought a whole new PC at the beginning of December I'm just waiting for the parts to arrive, but everything is taking really long But once they are here, I'll be able to render a lot faster Let's hope they arrive soon
Do you think you can add some caustics which doesn't seem to happen in the final render? Because apart from that it's pretty photorealistic and simple to achieve (which is great). Thank you!
Adding caustics to this scene wouldn't make it more realistic at all When I started using blender, I thought I had to have them Everytime I use glass, but in reality, you don't always have caustics In fact they only appear when you have a lot of light coming from one direction (for instance at direct sunlight, or when you put a flashlight directly next to the glass So if you want photorealism, you should let blender do it's thing, and when they appear, it's fine, when they don't, you most likely don't need them There is a lot of Tutorials online on how to fake them (I'm not interested in making one, as I think it doesn't add much to the scene and decreases believability) , so if you really want them, I recommend Gleb Alexandrov's tutorial
Blender is my only friend, so I play sad music since nobody likes me Jokes aside, I like the music and I think it might help people focus and fills in the spots where I'm not talking without being too distracting
Hey Philip, I've been experimenting with your glass shader setup and noticed something strange. I put liquid in one glass, and set a glass with no liquid next to it. The light that passes through the empty glass has a red tinge to it, while the one that is full of liquid (amber colour) casts a black shadow. What might the reason for this be? Edit: this was not the correct video where you set up your complicated RBG shaders, whoops
actually I sense sarcasm in this comment. The melancholic piano is just so distracting and there were some parts that just don't work (3:32 Shift+End hotkey doesn't work. also there was no info what does the red mean)
Having shortcuts that don't work on a 1 year old tech video is nothing extraordinary But shift+end is not what was asked The actual shortcut is Shift+N Red means that the normals of the object are facing the wrong dorection :) I chose melanchonic piano because it's easy on the ears, maybe a bit loud, bit it's a little less noticable in the newer videos, thanks for the feedback
ill add that to my Arsenal... Orange Juice is just a Volume Node (Principle) (Change the # of Bounces to Something Higher than 0 xD). and Water is Volume Scatter... You can also make Col-aid Looking Drinks.. xD
Hey, great tutorial- thanks a ton! One quick question tho. My glass would not see through. Instead it has this inverted reflection of what's behind the glass (in this case, the drawers and the floor are reflected on the glass) I think I messed up the geometry somewhere along the way but I just want to avoid the mistake if I were to do it again. Any suggestion?
Make sure youre using the cycles render engine! Glass does not work that well in EEVEE If youbare using cycles, select it and go into edit mode Press A to select everything and press shift+N That should fix the normals if they are inverted If it's none of that, tou probably have some overlapping geometry down at the bottom of the glass (inside)
In Blender 4.0.2 when I use Principled Volume to make the orange juice the "color" seens to work "inverted". I mean, qhen I choose blue my material become yellow... Thanks for this tutorial.
Great technique. Thanks! At the end though it looks like there might be something odd with the normals at the bottom of the glass. Kind of a pointy, wave-like pattern?
Thank you! It's just the glass refracting itself because the bottom is lifted up The normals are fine, I checked it You have a good eye though, I didn't even notice the waves, they disappear once you tilt the camera by even as much as half a degree sadly
@@philipkriegel Thanks. Would there be any benefit to making the glass bottom and/or liquid top surface with grid fill? I seem to recall a technique of using proportional editing on a grid fill to pull the liquid surface up slightly from the center to get a slightly convex shape to simulate the surface tension.
You could do that if the liquid is the focal point of your scene and you think that people will look at it a lot But people usually won't notice it's not there if you don't mention it Surface tention goes downwards though as seen in this image: previews.123rf.com/images/utima/utima1603/utima160300178/54252997-water-glass-isolated-with-clipping-path.jpg I hope I could help you with this and you can feel free to join my discord server should you have more questions :)
Very nice video! thx a lot! I have one question. What if I want to set the background to an object. For example, through the glass I want to see the object behind it, how do i do that? :(
If you followed the tutorial, glass in itself is transmissive (light passes through, so you can see what's behind it). If you however have a curved piece of glass, like a cup, what you are seeing might get distorted, especially if there is water inside. So if you have a glass that is a little bit flatter, you will be able to see through just fine, with curved glasses, you're always going to have a little bit of distortion, that's just how physics work unfortunately But generally, you should always be able to see what's behind it if you keep the roughness of both the glass and the liquid close to 0 (in my opinion, best at 0.01 Make sure to ask further questions if anything is unclear :)
Amazing tutorial, I found it very useful for my practices. Do you have an tutorial like a Sauce bowl o something similar, with a fluid/liquid but static? Thanks bro!
Hey there! Thanks, I'm glad you liked the tutorial, sadly I don't have that, boy you might just have given me an idea 👀 Expect something along these lines soon!
@@philipkriegel Usually I always see tutorials on liquids and fluids in motion here on TH-cam but only a few with static fluids like soda glasses with ice cubes or something like that but not with Sauces or other liquids that have pieces of solids inside. If you do, it would be super cool! Really thanks bro!
The reason why you see them in motion, is because that's the easiest thing to do. If you want a static fluid without simulating it, you would need to sculpt it and make sure it looks realistic. Thats why people choose to simply let the computer do the work :)
Someone please help, how do you get the glass to be so clear, every time i try this the glass comes out still noisy it never comes out as clear as his especially when i have a area where i can see another layer of glass through the first one
Make sure your roughness is reasonably low. Also make sure your normals are facing the right direction by selecting everything in edit mode and pressing shift+N. If you are still getting darker spots then make sure that under the light path settings you turn the glossy rays higher (something like 10 or 12) Hope this helps
If you mean plastic cups then no, they usually are shaped differently at the top and bottom and the materials are different as well If you're looking for plastic this is not the right tutorial for you, but thanks for the idea 👀
OMG! your left and right mouse buttons are switched! That really messed me up! I knew people did that but.... didn't catch it for a few. Ha. Good times. Learning so much.
Glad you learned something! When I started learning blender, right click select was the default setting, it was only years later that blender started asking you what you prefer when you boot up for the first time, but by then I got used to it already :D
It depends on what juice you tried making. If it's the apple juice, you might have turned the roughness up too high If it's the orange juice, you might also have the roughness too high, but that could also happen when pushing up the density too high as well If lowering either of them doesn't help, make sure to join my discord server and send me the file so we can look at it together :)
when i am dublicating the faces like you did to make the liquied its getting linked to the original object and not coming out as seprate object what to do
Tutorial is ok. I append a figure blend file, the glass is a big vase. No water, the optical distortion of thin glass cyclinder is as if a solid crystal ball effect. Not as in your HDR. Which I will not have because it just a dark theatre stage. So what is wrong? Will this not work for animation with moving camera/figures etc?
Hey there. I'm not sure if I understand your question Could you perhaps ask the question in a different way? If I get what you are saying, you're having trouble with the reflection and the refraction Are your normals pointing in the right direction? Are you using eevee or cycles? You can only render realistic glass with this method in cycles
That depends on the scene you are trying to render. This one should render perfectly fine with 600 samples, but some might need more or less, depending on the complexity of the scene

Hi!
Very nice tutorial. I'm especially impressed by your approach to realism... even going so far as to explain the reasons for your modelling.
This is something I found missing in so many - very good - tutorials and builds: things that _look_ good and real, but simply would work in the real world.

@@philipkriegel couldn't agree more learning about why something works is just as important as knowing how to do it

thank you so much very nice and i made it as well to the end ,, i'm learning blender so this was amazing looking for more and more explination
Many thanks again Philip! I wondered what the edge loops might be doing. I reduced the IOR value and that gives a result that I can use.
You're welcome :)
The IOR is the index of refraction
For the most realistic results, it should be set to 1.44-1.46 for glass and about 1.333 for liquids
Having an IOR of 1 is like looking at air
If you're unsure what the index of refraction is, I suggest you watch a video on it or read an article, as it's something every material has :)

I try to avoid creases because they don't add topology so you need a higher topology count to make them work
Also you would want a little bit of roundong on the top of the liquid to showcase the surface tention, which in the end, doesn't add much, but at least in some cases, it'll show you a reflective line where the liquid ends.

finally let's apply some water drops on a glass surface to be totally excited! =)
great tutorial!
Thanks a lot! :D
you are very welcome mate!
Hey Philip, I've been experimenting with your glass shader setup and noticed something strange. I put liquid in one glass, and set a glass with no liquid next to it. The light that passes through the empty glass has a red tinge to it, while the one that is full of liquid (amber colour) casts a black shadow. What might the reason for this be? Edit: this was not the correct video where you set up your complicated RBG shaders, whoops
2:21 haha it took me about 20 minutes to realize that you were selecting 4 layers not 2. Amazing tutorial, I love the music!
Thank you! I'm glad you liked it :D
actually I sense sarcasm in this comment. The melancholic piano is just so distracting and there were some parts that just don't work (3:32 Shift+End hotkey doesn't work. also there was no info what does the red mean)
@@annaczyz7185 no sarcasm
Having shortcuts that don't work on a 1 year old tech video is nothing extraordinary
But shift+end is not what was asked
The actual shortcut is Shift+N
Red means that the normals of the object are facing the wrong dorection :)
I chose melanchonic piano because it's easy on the ears, maybe a bit loud, bit it's a little less noticable in the newer videos, thanks for the feedback
@@philipkriegel thank you guys for answer!
Amazing tutorial, really helpful but I can't find light path, do you know why that is?
Make sure you're in cycles
Also what version of blender are you using?
@@philipkriegel you are right, my render engine was in Eevee instead. I really appreciate the fast response from you, you are lovely
ill add that to my Arsenal...
Orange Juice is just a Volume Node (Principle) (Change the # of Bounces to Something Higher than 0 xD).
and Water is Volume Scatter... You can also make Col-aid Looking Drinks.. xD
How is moving the bottom up happening only along one axis? You blaze through this part and it's unclear
Hey, great tutorial- thanks a ton!
One quick question tho. My glass would not see through. Instead it has this inverted reflection of what's behind the glass (in this case, the drawers and the floor are reflected on the glass) I think I messed up the geometry somewhere along the way but I just want to avoid the mistake if I were to do it again. Any suggestion?
Make sure youre using the cycles render engine!
Glass does not work that well in EEVEE
If youbare using cycles, select it and go into edit mode
Press A to select everything and press shift+N
That should fix the normals if they are inverted
If it's none of that, tou probably have some overlapping geometry down at the bottom of the glass (inside)
So nice
Good choice of background music, It was relaxing, Also very helpful.
Thank you! I'm glad you liked it
To me it sounded like sitting in the waiting room at the dentist's office :(
You better floss, or I won't delete the default cube in the next tutorial.
@@philipkriegel I do better than that: I use a WaterPik every night.
Nice.exe
Brilliant

hank you!
In Blender 4.0.2 when I use Principled Volume to make the orange juice the "color" seens to work "inverted". I mean, qhen I choose blue my material become yellow... Thanks for this tutorial.
Thanks for your tutorial. But I am not getting a result close to you. I am not getting the color right its always too dark.
amazing thanx mate
You're welcome
when I hit alt+E the bottom face extrudes only the top face .It leaves the bottom part blank
Blender 4.0
fantastic!
Great technique. Thanks! At the end though it looks like there might be something odd with the normals at the bottom of the glass. Kind of a pointy, wave-like pattern?
Thank you!
It's just the glass refracting itself because the bottom is lifted up
The normals are fine, I checked it
You have a good eye though, I didn't even notice the waves, they disappear once you tilt the camera by even as much as half a degree sadly
@@philipkriegel Thanks. Would there be any benefit to making the glass bottom and/or liquid top surface with grid fill? I seem to recall a technique of using proportional editing on a grid fill to pull the liquid surface up slightly from the center to get a slightly convex shape to simulate the surface tension.
You could do that if the liquid is the focal point of your scene and you think that people will look at it a lot
But people usually won't notice it's not there if you don't mention it
Surface tention goes downwards though as seen in this image: previews.123rf.com/images/utima/utima1603/utima160300178/54252997-water-glass-isolated-with-clipping-path.jpg
I hope I could help you with this and you can feel free to join my discord server should you have more questions :)
pained me when i noticed you didnt switch to gpu rendering at the start
Very nice video! thx a lot!
I have one question.
What if I want to set the background to an object. For example, through the glass I want to see the object behind it, how do i do that? :(
If you followed the tutorial, glass in itself is transmissive (light passes through, so you can see what's behind it). If you however have a curved piece of glass, like a cup, what you are seeing might get distorted, especially if there is water inside. So if you have a glass that is a little bit flatter, you will be able to see through just fine, with curved glasses, you're always going to have a little bit of distortion, that's just how physics work unfortunately
But generally, you should always be able to see what's behind it if you keep the roughness of both the glass and the liquid close to 0 (in my opinion, best at 0.01
Make sure to ask further questions if anything is unclear :)
@@philipkriegel thx for your replay, I appreciate 🙏
You saved me ! Hope you get surprise from life for this
now im subscribing ty mate
Thank you too :)
Amazing tutorial, I found it very useful for my practices. Do you have an tutorial like a Sauce bowl o something similar, with a fluid/liquid but static? Thanks bro!
Hey there!
Thanks, I'm glad you liked the tutorial, sadly I don't have that, boy you might just have given me an idea 👀
Expect something along these lines soon!
@@philipkriegel Usually I always see tutorials on liquids and fluids in motion here on TH-cam but only a few with static fluids like soda glasses with ice cubes or something like that but not with Sauces or other liquids that have pieces of solids inside. If you do, it would be super cool! Really thanks bro!
The reason why you see them in motion, is because that's the easiest thing to do. If you want a static fluid without simulating it, you would need to sculpt it and make sure it looks realistic. Thats why people choose to simply let the computer do the work :)
Someone please help, how do you get the glass to be so clear, every time i try this the glass comes out still noisy it never comes out as clear as his especially when i have a area where i can see another layer of glass through the first one
Make sure your roughness is reasonably low.
Also make sure your normals are facing the right direction by selecting everything in edit mode and pressing shift+N.
If you are still getting darker spots then make sure that under the light path settings you turn the glossy rays higher (something like 10 or 12)
Hope this helps
Thanks 謝謝
What was your video card when you recorded this video?
What about plastic? Does this video apply to that as well?
If you mean plastic cups then no, they usually are shaped differently at the top and bottom and the materials are different as well
If you're looking for plastic this is not the right tutorial for you, but thanks for the idea 👀
OMG! your left and right mouse buttons are switched! That really messed me up! I knew people did that but.... didn't catch it for a few. Ha. Good times. Learning so much.
Glad you learned something!
When I started learning blender, right click select was the default setting, it was only years later that blender started asking you what you prefer when you boot up for the first time, but by then I got used to it already :D
Wow
hey... thank u so much
You're welcome
my juice is the right color in cycle but turns plain white (not transparent) in render :( what did I do wrong
It depends on what juice you tried making. If it's the apple juice, you might have turned the roughness up too high
If it's the orange juice, you might also have the roughness too high, but that could also happen when pushing up the density too high as well
If lowering either of them doesn't help, make sure to join my discord server and send me the file so we can look at it together :)
When the liquid is more transparent, like the apple juice, the top should be more reflective when viewed from below... how would you make this?
You don't need to change anything, it depends on the lighting conditions and the camera angle
Wow super realistic
Thank you :) It is not that hard either
when i am dublicating the faces like you did to make the liquied its getting linked to the original object and not coming out as seprate object what to do
You need to press "P" and then "selection"
really good video 👍
Thank you ^^
Tutorial is ok. I append a figure blend file, the glass is a big vase. No water, the optical distortion of thin glass cyclinder is as if a solid crystal ball effect. Not as in your HDR. Which I will not have because it just a dark theatre stage. So what is wrong? Will this not work for animation with moving camera/figures etc?
Hey there.
I'm not sure if I understand your question
Could you perhaps ask the question in a different way?
If I get what you are saying, you're having trouble with the reflection and the refraction
Are your normals pointing in the right direction?
Are you using eevee or cycles?
You can only render realistic glass with this method in cycles
Please join our discord server so we can further help you
is 600 samples enough to create no noise rendered images?
That depends on the scene you are trying to render. This one should render perfectly fine with 600 samples, but some might need more or less, depending on the complexity of the scene
Good lesson. Many thanks! But I didn't get orange juice. I'm probably doing something wrong. I don't understand English well.
You use the volume shader to make the Orange juice less transparent and give it color
@@philipkriegel Thanks, I will try.
