there are many useful addons that are turned off by default turn all of them on especially add extra mesh you can add gears or palnes using mathematical equations
i have never doubted any of your tutorials cause i always learn one or two things from them,keep up with the good work,may God Bless you for your Artistic Skills and for the help you have been giving us..
I drank a beer while watching this video and somehow tool lots of good notes (I may gave to watch this again in the morning if my notes are not good in reality). Thanks for the great tutorial. I also appreciate the background details and research that make this tutorial more rich than other bland tutorials out there.
The bubbles form in places that allow better nucleation effect - like impurities and scratches on the surface of the glass itself or pieces of dust and grease being result of not cleaning the glass well. So in a clean, freshly washed glass there would be only a few subtle streams of bubbles in your beer. So, knowing this, now you if you get a beer in a bar and you see a lot bubbles creating in the liquid, especially on the sides of the glass, then you know that it wasn't cleaned and rinsed before pouring beer in.
True, though you used to get a lot of bubbles forming due to the imperfections in the glass when the beer glass was made (so it wasn't necessarily dirty yet still produced a lot of bubbles) but with the amazingly precise manufacturing we have now, very few imperfections make it into the glass so beer glass manufacturers add the equivalent of your bubble emitter planes, laser etched into the glass in order to create bubbles. brucrafter.com/wp-content/uploads/2019/03/etched-nucleated-bottom-beer-glass-muffin-top-review.jpg
A precise video for those who want to make realistic fluids in containers. I experimented with a couple of HDRIs. The results created a conducive environment for the beer, like in a in a hotel or in a studio. Really enjoyed this tutorial and learnt a lot. Thank You.
These are great tutorials to learn your way around Blender. Taken me about 3 days to follow this all the way through, as it's hard to keep track at some points but love doing them and very well explained 👍🏼
OMG - I've seen the thumbnail for a couple of days but thought it was about home brewing! I'm so glad your graphics, after 38 years* in CG, fooled me! *I was animating graphics on my ZX80 in 1980!
Great tutorial. I believe I heard once that bubbles tend to form where ever there is an imperfection or particle on the glass. A perfectly smooth glass would have bubbles form randomly but since no glass is perfectly smooth they all seem to form from common areas, those areas being a spot with an imperfection... and now I want a beer.
20 People disliked the video because they thought they are going to learn how to make beer in a blender device xD PS: Why don't you monetarize your videos ?! Every penny that you earn would be absolutely deserved!
If anyone is wondering how to select all the faces at 6:48 just use "Alt-RMB" when you select each line. ANd hold shift when selecting the second line so that you select them both.
The bubbles are emitted from little scratches. By the way: it is the same with cheese. If you'd take 100% clean milc, you wont get any holes. So cheese factorys really add some flour to get bubbles. (If you wonder, why i am telling this: i used your beer tutorial to fix a wine scene of mine, wich includes cheese, too. I'll post it, when it's finished.)
Dude, Andrew...I just gotta say I've got to know 3D modelling so much more since I started watching your tutorial videos and so I thank you so much for that and keep doing what you do because you're awesome :)
When adding the face on the bottom of the glass...easy fix for the wierd shape that results. Inset bottom face, drag to end edge, then edge loop and drag to bottom. if you want the slight bevel, don't drag faces all the way to the edge
Fizzy drinks bubble from single points because they need to nucleate. Basically, the nucleation points are small enough, that the gas in the beverage can escape into them easier than the liquid, and then cluster together and bubble out. That is the easy explanation. It's also the same reason why Mentos make soda explode. The surface of a Mento is covered in pits, which act as nucleation points.
Thank you so much for this one. I have been wrestling with the intricacies of liquids in glasses for months. I was doing whiskey on the rocks. Your particle bubble ice cubes from the splash drink tutorial made the day but getting volumes and lighting right for the ice protruding from the top of the fluid was KILLING me. I was throwing the Knife Project tool around like it was beads at Mardi Gras. I think I can apply the tricks I learned here to get past that. And now I know how to do the "sweat" above the drink, too. Thanks again!
About bubbles: 1) realistic bubbles has a lower size when they are lying on the bottom than when they are blowing up to the surface. It's like inflating a balloon. The reason is the pressure inside the liquid is linearly increasing as we go to the bottom and it comprises the bubbles. 2) Another thing is the separation between bubbles because they are more separated each time going up, because the bigger they are the floating force push it up stronger and they are growing up as they are going up to the surface, positive feedback. 3) Last thing, no linear trajectories is about vortex shedding around the bubbles as they are passing thought fluid (see: von Karman street) it depends on thr Reynolds number, etc...
Hi Blender Guru: a quick response to your bubble question. In beer a lot of gas (mostly CO2 and air) is soluted. However due to the apolair nature of gases, i.e. they do not like to mix with water just like oil. Whenever there are apolair particles (tiny microscopic impuritites like dust particles for example) these molecules adhere to the particles. Bubbles are formed whenever enough gas molecules stick together. If the particles are big enough you can actually see this with the naked eye: just boil an egg for example, you'll see bubbles forming on the egg. The impurities in beer are not visible to the naked eye and the float around via a random pattern (a.k.a. Brownian motion (sounds familiar?)). That's why these streams of bubbles seam to spawn at random locations in the beverage.
Bubbles do that because of nucleation sites. Basicaly the gas in the liquid needs a place to diffuse out and form a bubble, It can´t do that spontaniusly. The glass has tiny imperfections that make nucleation sites where gas can form bubbles and then rise up. Some materials have more imperfections hence more nucleation sites, thats why if you pour a beer in a plastic cup it will have more foam and its the same reason mentos create that extreme foam in sodas.
For realistic IOR for the bubbles, I think the reason why setting the IOR to 1 doesn't produce a good value is because the light refraction is determined by the surface, not by volume. If you put an icosphere with an IOR of 1 inside of another object with higher IOR, blender does not calculate the IOR of the fluid. So having an IOR of 1 for the bubble has no effect. Instead, try setting the bubble's IOR to be the same as the fluid, and flip the normals to face inwards. That way, cycles will treat the side which the normals are pointing to as the same as air. I'm not exactly sure if this is how cycles rendering for refraction works, but it's the best explanation I can think of. I think it is (theoretically) possible to use a stack data structure for each sample, to keep track of the IOR which the sample last passed through, which could be used to calculate better results, by pushing the new IOR onto the stack whenever it passes against a normal plane, then popping that value off of the stack when passing with the direction of a normal to simulate the entering and leaving of a solid object. Though this would take longer to render and require more memory. That's why I think that cycles calculates refractions manually (the way I described it earlier) instead of using an IOR stack data structure.
You should really flip the normals to make it look right! When light goes from air to glass, there's an IOR of ~1.45, and when light goes from glass to water, there's an IOR of 0.85. Since You can't have IOR lower than 1.0, you must make the IOR 1.15 and flip the normals. If cycles volumetrics doesn't work with flipped normals, you should make the volume a separate object (with normals outwards), and pull it in a bit if the overlapping faces are a problem.
I wish you still continued to use the new format you used in your "Subway" tutorial. It made the video short enough for people just interested in blender to watch something (like me), but long enough and includes all the necessary details for anyone trying to follow along.
I've been using these tutorials since I started learning Blender, but I'm at that phase now where I'm watching hour long videos and picking up one or two really interesting tips and turning to forums for the really difficult problems I run into. Any chance you might make a bunch more quick tip videos for the intermediate Blender artist? Just some short, interesting facts or common mistakes or things that could help would be awesome.
Your tutorial are amazing, thank you so much for existing. I'm going crazy over this, someone please tell me how did he select a whole edge, a whole group of vertices simply with one single click?? How did he do it so fast without hitting "B" or "C"?
I followed along with you at .5 speed and laughed my ass off because you sounded drunk! haha. but... it was easier to follow the steps and not have to pause as much. Thanks for posting!
Would be really good if you could link the image files in the description Andrew. I couldn't find them on Blenderguru.com, I had to go get them from some Russian site that has posted the tutorial as text/images.
Right i know this is a few years too late, and you probably have had the answer by now, but i didnt see it in the comments and couldnt be bothered to keep looking. and since I work with beer i figured Id answer you. The bubbles come out of nucleation points in the glass. C02 in solution needs a nucleation point to form bubbles, that may be a tiny spec of dust, a malformation of the glass, or as its usually the case a pre made nucleation point which is usually a design in the bottom of the glass made of tiny porcelain dots. it will work with any liquid that has c02 in solution in any concentration, the nucleation point gives the co2 a point to come out of solution, and thats why bubbles always come up in a line from the same spot. and beer glasses have those points to make the beer look livelier.
I love your tutorials, but might I suggest an intro theme song, bright colored Korean subtitles, and special guest appearances in your tutorials please?
thanks for the wonderful tutorial.. just started using blender i come from 3ds max i was a beginner there too. But blender caught my eyes.. would be great if you could teach the particle system little more detailed. thanks
Andrew, about the bubbles material. If you look at the 1.45 IOR bubbles shader inside the beer, you'll notice that they actually act like a glass (see the difference between them and the booleaned ones). It's like a glass bubbles inside a glass (which doesn't make sense in the real world). And you couldn't use IOR=1 either, as you mentioned. And you couldn't use boolean on particles (not converted, of course). Well, i found a trick. Set the IOR
Ugh! Blender! Ugh. Great tutorial.... here are a couple of other things I learned through frustration: 1. Make sure you are in Blender's Cycles Render (drop down menu at top middle of interface) before importing images as planes 2. Someone at Blender decided that Auto Perspective would be switched ON in 2.7, so Blender would flip to Perspective View from Orthographic every time I orbited the object. This was driving me insane(er). It's an easy fix under the User Preferences > Interface. Hours of frustration there. But again, GREAT TUTORIAL. And if I live through using Blender, I will finish my beer glass.
Actually I think the IOR of the bubbles is weird because cycles does the IOR calculations based on the previous domain so 1 to 1.45 there is a difference and 1.45 to 1 there is not because unlike IRL it doesn't reverse the effect but instead treats it like a 1 relative to 1.45 aka beer to bee. Acutally you would have needed to do an IOR lower than 1 for the bubbles for it to be realistic.
That's why u are a great teacher Andrew :o it's in your DNA you brightened my days thx u man! if I had someone like u in high school I would be PHD in somthing lol I dont know what but somthing like I m gonna be PHD In Blender because of you x)
hey Andrew! awesome video, your tutorials are extremely helpful! By the way, did you ever consider doing tutorials on low-poly models for games? You are a great teacher, and I think it will bring you more views, and you will help a lot of people as well! Thank you!
Wouldn't it be better to choose the appropriate IORs? 1.63 for glass and 1.345 for beer. These changes would probably be really subtle, but typing in these values when setting up the BSDF isn't much work either.
It's wonderful lesson, i've got so much realistic glass of beer! But i hopedto study Flip Fluid Simulation...:D Well, nevermind) I was pleased with the result of the lesson!!
When you do the uv unwrap as cylinder projection, make sure that you're in orthographic view and view it from the front. Otherwise the projection will be skewed.
Few things. 1) Love the videos and you're hilarious. 2) The blender Guru link is broken. 3) I know you added details to the outside of the glass on the last render there... cheater hahaha. How did you achieve that? Thanks!
Just saw this in my subscription feed... thought it was "How to make a beer in a blender" ... genuinely thought it was a tutorial on how to make beer, then I saw Andrew Price's face at the side... oh well haha.
***** Regarding that Apple iPhone question you mentioned. It is an issue with the person holding their phone vertically while filming (which is portrait mode) instead of turning it sideways so it flips it to widescreen (landscape) mode. Same is true with tablets and the other smart phones (like Android and Windows). People just need to remember to film in landscape mode.
Thanks for your tutorials! Only thing I'm missing is the little droplets on the outside of the glass suggesting it's a real cold and fresh beer. How can I achieve this? Great work, I'm just thinking about subscribing to your nature academy...
You can calculate the actual IOR inside the beer if you learn physics I think, considering the beer is 1.33, I *_THINK_* the bubbles should have a negative value
woops I came to this video thinking it was how to make a drinkable beer in a blender. Lol I watched the video though, good job nice video very informative
Even after 7 years, its still useful. Thank you Andrew
"Import Images as Planes" 8 years on and I never noticed that...
...tis why I still watch tutorials.
there are many useful addons that are turned off by default turn all of them on
especially add extra mesh you can add gears or palnes using mathematical equations

"Actually don't do that that looks horrible." It's details like these that really make your tutorials good!
This is by far the most amazing blender tutorial I ever followed. Took me an agonizing week but so worth it. Thanks so much man
These are great tutorials to learn your way around Blender. Taken me about 3 days to follow this all the way through, as it's hard to keep track at some points but love doing them and very well explained 👍🏼

ZorlacSkater actually I disliked because of beer 😊
why?
It's OK, I liked it twice because beer
Iorweth he already makes ass tons of money off of blender lol, it’s his job
You should be a stupid fool if you thought you could make beer mixing something together. It's not a way that alcohol is made
If anyone is wondering how to select all the faces at 6:48 just use "Alt-RMB" when you select each line. ANd hold shift when selecting the second line so that you select them both.
omg, thank you :D
wow I didn't thought that blender could make this as beautiful
MY TWO FAVORITE THINGS COMBINED>>> BEER AND BLENDER!
Brooooo!

It must be vintage cheese by now ;-)
Dude, Andrew...I just gotta say I've got to know 3D modelling so much more since I started watching your tutorial videos and so I thank you so much for that and keep doing what you do because you're awesome :)
I love how exasperated you are with the haters in this video. It's so entertaining!
Aha the Ancient Blender tutorial 😂
In Cider glasses, they have rough rings at the bottom to make the bubbles so that there is a more consistent formation of bubbles :)
Hey Andrew, never lose your sense of humor.
Anyone else see the "blend responsibly" thing?
Thanks andrew to showing us best blender tutorial
When adding the face on the bottom of the glass...easy fix for the wierd shape that results. Inset bottom face, drag to end edge, then edge loop and drag to bottom. if you want the slight bevel, don't drag faces all the way to the edge

it'd be cool to get an up dated version of this. maybe even an animation. with text in it,
2021 and this is still great content.
Oh this is an old one. Loving it.

The curve you mentioned in the fluid is called 'the error of parralax'

You are so good at what you do. Great personality aswell.
Wow, 2014. Still going through your videos randomly. Good stuff.
Love the tuts. Just slow it down a bit for us newbies. Thanks

Andrew, I am your fan! Fantastic job on all Tutorials!
a beer brewer here in austria told me once, that there are rough spots made on the bottom of glasses. and all bubbles form on those rough areas.
Hi!
Thank you very much for this tutorial.
I learn a lot with the video!
I recommend this tutorial for everyone!
You should really flip the normals to make it look right! When light goes from air to glass, there's an IOR of ~1.45, and when light goes from glass to water, there's an IOR of 0.85.

Bubbles form on microscopic scratches in the glass, that's why they tend to form in the same place all the time.
good tutorial man as always they help a lot and don't stop with your joke is more interesting and funny. love your tutorials...
I wish you still continued to use the new format you used in your "Subway" tutorial.
It made the video short enough for people just interested in blender to watch something (like me), but long enough and includes all the necessary details for anyone trying to follow along.
Hey Andrew, surface tension of water is great.
now how do you print the beer so you can drink it?
That's Blender v.139412.2
You need a 3d printer! lol
3d printer :D
Use the liquify tool in photo shop
Real life printer
lol when you said your computer was gonna crash I got scared and saved my computer. XD
I've been using these tutorials since I started learning Blender, but I'm at that phase now where I'm watching hour long videos and picking up one or two really interesting tips and turning to forums for the really difficult problems I run into. Any chance you might make a bunch more quick tip videos for the intermediate Blender artist? Just some short, interesting facts or common mistakes or things that could help would be awesome.
Dude you are well good at blender I wish I had the skills you have
Thanks again, Andrew. Excellent tutorial! Looking forward to the Architecture Academy!
Andrew, this tutorial was great, thank you.
I really enjoy your tutorials, you are pleasant to watch and you're quite a funny fellow!
Thanks a lot, I learned something new again!
It looks nothing like the finished render. You should do it again.
Just kidding. Thanks A LOT for your work !
Your tutorial are amazing, thank you so much for existing.
I'm going crazy over this, someone please tell me how did he select a whole edge, a whole group of vertices simply with one single click?? How did he do it so fast without hitting "B" or "C"?
Yaaas! The vertical filming rant is legit +1
Worlds quietest default audio levels. Crank up that mic Andrew!
2.5cm x 10cm is sooooo wrong. is it a pint for ants?
the radius is 2.5, the diameter is 5 cm
still way too small. a radius of 3,5cm would be more appropriate i think.
it is still less than 2 dl
Got it :D en.wikipedia.org/wiki/Pint_glass
He doesn't care about the size in blender, he cares about how it looks.
I followed along with you at .5 speed and laughed my ass off because you sounded drunk! haha. but... it was easier to follow the steps and not have to pause as much. Thanks for posting!
Would be really good if you could link the image files in the description Andrew. I couldn't find them on Blenderguru.com, I had to go get them from some Russian site that has posted the tutorial as text/images.
Right i know this is a few years too late, and you probably have had the answer by now, but i didnt see it in the comments and couldnt be bothered to keep looking.
and since I work with beer i figured Id answer you.
The bubbles come out of nucleation points in the glass.
C02 in solution needs a nucleation point to form bubbles, that may be a tiny spec of dust, a malformation of the glass, or as its usually the case a pre made nucleation point which is usually a design in the bottom of the glass made of tiny porcelain dots.
it will work with any liquid that has c02 in solution in any concentration, the nucleation point gives the co2 a point to come out of solution, and thats why bubbles always come up in a line from the same spot.
and beer glasses have those points to make the beer look livelier.
You work with Beer? That's a dream job right there! Can I ask what you do
I'm a Beer enthusiast as well as a 3D hobbyist!
If a beer took that long to make for me, I would've already been gone before my beer was served. LOL jp. Good Job!
I love your tutorials, but might I suggest an intro theme song, bright colored Korean subtitles, and special guest appearances in your tutorials please?
Awsome vid. Been playing with this all day. Looking forward to more of ur great lessons.
This was an awesome one (usually the case with your tuts). It looks as though the DOF in Blender isn't knowing it's looking through glass :-O.
thanks for the wonderful tutorial.. just started using blender i come from 3ds max i was a beginner there too. But blender caught my eyes.. would be great if you could teach the particle system little more detailed. thanks
This is what i needed!
how to select the inside vertex by itself with grabbing the outside?
Andrew, about the bubbles material. If you look at the 1.45 IOR bubbles shader inside the beer, you'll notice that they actually act like a glass (see the difference between them and the booleaned ones). It's like a glass bubbles inside a glass (which doesn't make sense in the real world). And you couldn't use IOR=1 either, as you mentioned. And you couldn't use boolean on particles (not converted, of course). Well, i found a trick. Set the IOR
You are the Blender Guru... =) Thanks for your time and your videos, keep it up!!
Ugh! Blender! Ugh. Great tutorial....
here are a couple of other things I learned through frustration:
1. Make sure you are in Blender's Cycles Render (drop down menu at top middle of interface) before importing images as planes

Acutally you would have needed to do an IOR lower than 1 for the bubbles for it to be realistic.
Thanks for the tutorial, learned some more useful things :) Though sometimes you forget to describe what you're doing when you're bantering about :p
Nice tutorial. I dont think you should edgesplit the surface though because essentially all it does is remove the refraction effect trough the liquid.
That's why u are a great teacher Andrew :o it's in your DNA you brightened my days thx u man! if I had someone like u in high school I would be PHD in somthing lol I dont know what but somthing like I m gonna be PHD In Blender because of you x)
A great teacher would explain shit step by step.
Great tutorial, i am a beginner at blender and this was not too hard to follow :)
hey Andrew! awesome video, your tutorials are extremely helpful! By the way, did you ever consider doing tutorials on low-poly models for games? You are a great teacher, and I think it will bring you more views, and you will help a lot of people as well!
Thank you!
Great Video - thanks!
Wouldn't it be better to choose the appropriate IORs? 1.63 for glass and 1.345 for beer. These changes would probably be really subtle, but typing in these values when setting up the BSDF isn't much work either.
When he said: "Time for the fun stuff, the beer" I honestly 'whooped' like crazy!
Can you please mention the keyboard shortcuts you're using when making tutorials? Hard to follow along when things are just appearing out of nowhere
Look at the lower left corner...
Its so amazing tutorial 💜💜👍👍
Andrew your the man, man!
I just trying to make it,thanks...maybe the summer coming!
It's wonderful lesson, i've got so much realistic glass of beer!
But i hopedto study Flip Fluid Simulation...:D
Well, nevermind) I was pleased with the result of the lesson!!
When you do the uv unwrap as cylinder projection, make sure that you're in orthographic view and view it from the front. Otherwise the projection will be skewed.
Few things. 1) Love the videos and you're hilarious. 2) The blender Guru link is broken. 3) I know you added details to the outside of the glass on the last render there... cheater hahaha. How did you achieve that? Thanks!
for the residue the normals should point outward.
For the air bubbles in a liquids IOR usually = liquid IOR / 2
So IOR about 0.75 works well for me.
Just saw this in my subscription feed... thought it was "How to make a beer in a blender" ... genuinely thought it was a tutorial on how to make beer, then I saw Andrew Price's face at the side... oh well haha.
Great!!!! It's really usefull! Hi from Spain!
NICE WORK
Brilliant as per usual.
***** Regarding that Apple iPhone question you mentioned. It is an issue with the person holding their phone vertically while filming (which is portrait mode) instead of turning it sideways so it flips it to widescreen (landscape) mode. Same is true with tablets and the other smart phones (like Android and Windows). People just need to remember to film in landscape mode.
You still got it Andrew. Epic stuff :D
Thanks for your tutorials!
Only thing I'm missing is the little droplets on the outside of the glass suggesting it's a real cold and fresh beer. How can I achieve this?
Great work, I'm just thinking about subscribing to your nature academy...
Really very helpful tutorial for us
You can calculate the actual IOR inside the beer if you learn physics I think, considering the beer is 1.33, I *_THINK_* the bubbles should have a negative value
i just woke up, and i saw the the internet was gone, and the video stopped at 16:52 LOL xD
Great tutorial , don't make fun of being an alcoholic
woops I came to this video thinking it was how to make a drinkable beer in a blender. Lol I watched the video though, good job nice video very informative
