If all tutorials were like this, people would be learning Blender in a month. Amazing job!
Love that this isn't a "do this, click that, set this" type of video and he actually explains WHY!! More TH-camrs should take notice of this.
Thanks a lot. You explanation got a different project working for me because I had a better understanding of the why.
right
watched about 15 of these before this one actually made sense to me.👌👌 cheers.🌟
This is so useful, much quicker than trying to play with the settings on a local machine & waiting for it to compute. Thank you!
And that's how you got a subscriber. I have been stuck for like a month in this part. Now its starting to make sense.
This is the best tutorial I have ever followed. Sounds like an AI. Well done thanks!
The most dedicated tutorial ever
Hey, I'm just starting to get into making soft and tNice tutorials 17 minute video helped a LOT MORE than those one hour long tutorials out
TNice tutorials is THE most helpful tutorial on TH-cam imo. I am starting production in Hardstyle, and I find soft soft really useful
This is one the THE BEST and most in depth and educational video ever. A video that explains the mechanics of why things work rather than just "click this and it will work"
Thank you SO MUCH for explaining how cells work from the get go. Now I'll now exactly how to scale the resolution, the domain and the flow object properly!
Thank you very much for this video, MK Graphics. The best video about fluids out there, hands down. Great video!
Amazing in-depth video. It's extremely useful to understand what each setting does, so thank you so much for making this.
Finally a video that explains the fluid settings. Thank you very much.
Thank you so much for that tutorial, i like that you just start to explain the basics of every aspect, what they do and how to set up for your own purpose that i haven't heard of from others youtubers
The most breaking tutorial for fluids, TYSM for this video, animated examples for different values explaining it much better than just a tips inside of a Blender
Timesteps is the setting I've been looking for to solve the issue I was having with the velocity.
Watched so many fluid tutorial. This is the best. Thanks
This is what I am looking for today. Thank you very much
Best blender fluid walkthrough/tutorial I've seen!
Thank you very much for this video. The best tutorial I ever seen about fluid system.
Extremadamente útil este tutorial, muchísimas gracias por tomarte el tiempo de hacerlo! creo que es la mejor guía que conseguí de todas las opciones!
Great tutorial! You covered a lot ground here. Very helpful thanks!
This is the most helpful guide I could find
Bravo 🎉
Just what i needed. Thanks!
Amazingly helpful! Thank you, worth every minute!
Very great tutorial, thank you for your efforts
This is terrific! Thank you
Love the tutorial bro! Probably the most helpful on simulation for me! Robotic voice is kinda annoying but appreciate your effort! Thank you for this! Here’s a heart with a subscribe ❤️ ❤️
Great video! Thank you!
Very nice and deep explanation thankyou so much 🙏🏼🙏🏼🙏🏼
I was struggling to learn fluid simulation and i was not able to understand the option i have seen so many tutorials but thanks to you ...for bringing such a beginner friendly tutorial easy to understand!
well detailed for each function with previews ..for water simulation. its very good for a beginner thanks
Two days stuck trying to do the simplest simulation, following at lest 3 different tutorials. Thank you for the amazing and complete tutorial.
I had a problem where the liquid doesn't show, if someone happens to get the same error:
· 1: Remember to check "liquid" under domain.
· 2: By default blender first frame is 1, in frame 0 you won't see the liquid.
· 3: Change the resolution with the slider arrows, under domain.
What tutorials did u watch tho. Every tutorial I have watched told u to check "liquid" , what shitty channels did u watch from. Come share so we know not to watch theirs
Thanks, this was really useful and well presented tutorial.
Thank you. That is so helpful!
thanks for this!!! It answered something I have lost days trying to find an answer for!
Perfect tutorial on the subject
well explained and very easy to understand.
thanks a lot!!! so nice reverb
Best fluid guide!
Thank you, this was very helpful 🙂
super nice tutorial :3
Hey mate, big thanks from brazil! liked subscribed and bigged up
This is such a great educational video! Thank y oh for making yhisv
Nicely explained 😍❤️
you do great tutorials on Blender
Very nice!
very helpful!Thx
Thank you so much ❤
This guide is great
Its helps me a lot
Thank you 💥
very good. thanks
Really good and explain video!
subscribed you are a awesome teacher.
It's vvery usefull video. Easy to understand.
thanks man!
amazing video
Thank you very muck
3.6.10 working WOW!!😘
This is a treasure trove of information. Why didn't you delve into a lesson about rigid body constraint
Thx u. There are lots od topics to lecture.Also I have a plan to make a tutorial about rigid body constraints.
Best video about fluid dynamics, despite the hallucinatory effect that voice has on me
Thanks for nice comment. I have changed that AI voice. I have been using new AI voice in the my lastest video. If u have enough time ,pls watch my lastest tutorial,and give me idea which one is the best voiceover. Thanks in advance.)
best on the internet
U BEST!!!
You Best!!!!
This is a great tutorial and the AI narrator makes for an entertaining viewing experience...
...in the other words...
...it's hilarious :P
You deserve a sub and a like
best tuto at online. thanx for this. i have a small issue, when i export as alembic. splash and foam scales down at another 3d program like c4d. bu fluid scale is normal. any ideas ?
now i am in a good mood
Really detailed Tutorial, Thanks a lot
The voice software you are using a little robotic like, I'm sure there are way better human like voice software. Try to Find that.
Hope your channel will grow into Huge
Thank you for your nice comment.)Actually my voiceover software is not robotic completely. It uses artificial intelligence. But yes must be better softwares. You can recommend me if you know.Thank you again.
Thank you for this beautiful video, MK Graphics! Is it possible to obtain the physical values for velocity and pressure for the flux of liquid/gas in Blender?
Thank you. Unfortunately I dont have any idea.
@MK Graphics is there a way to control/prevent the volume gain problem through high fluid velocity like in 23:36 or 35:53 ?
This Video is really good, thank you.
This tour of the Fluid Simulator settings is enlightening in ways that the typical how-to video isn't.
I can't imagine anything better for making progress on the road to mastering fluids, except maybe this: a video that goes over the several most common problems with fluid simulation.
Myself, I often try to set up a simulation but nothing at all flows out. Why? Domain set to default "gas", or the Inflow object is too small, or ... I could make a list! Or I see the fluid flowing in the 3D editor, but rendering shows nothing. Why? I turned off the domain box visibility in Object Properties - I mean, do we want to see a big box in the final render? But it should be kept on. If it's not that, it's another mistake... I could make a list! Fluid particles shooting off to infinity. Fluid flowing through alleged obstacles.
We all got stuck, and still get stuck, forgetting settings or doing zany things.
Any tips? I’m a newbie learning
why mesh option doesn't work for me ?? please help
22:47
Hi there! Thank you so much for your tutorial ! It's super helpful n exactly what I'm looking for.
I have a question,I followed your steps, but the fluid particles are in bigger size(like balls lol) instead of small particles shown in your video.Plz help me out if u know how to solve this problem..🙏I guess sth went wrong with my setting🥲
Hello thanks for ur nice comment. Most probably your particles size value on the viewport is higher than default. To fix this,click on the particle properties tab,select the liguid particles,expand the viewport section,and set the particles size value to 0.01 again.
@@GraphicsMK Thank u sm!
i dont have time to turn up audio. how do i get rid of the stupid blue and green velocity particles?
I have the Problem that the Liquid domain is a solid Block and when i go to solid mode you cant see the liquid because the domain blocks the view. Does anyone knows how to Make the domain unvisible?
go to viewport display in Object mode with the domain selected and then change "display as" from solid to wire.
"The simulation will not work if flow object is smaller than the resolution cube". You mentioned in this tutorial. I looked at the flow and the cube at the corner of the domain. If those were the ones being referred to. what would indicate their disparity? Which slot must be adjusted?
I dont understand what u ask exactly.But you can decrease the resolution cube size by increasing the resolution division value. Or u can scale up the flow object.
@@GraphicsMK ok. Thanks.
Actually epic.. bro, can we simulate this in a huge scale? Like the size of a huge ocean? If you have a powerful enough computer?
No,almost it is not possible to bake such a huge scale simulation.Maybe ur harddisk wont be enough for baking data.We use Ocean modifier for this.Thx for remind me. Next tutorial will be about Ocean modifier.
@@GraphicsMK sure thanks! Well if I can buy say hdd of size like 10 terabytes... Can we baka it such way? Is it possible? If anyone had access to such stuff? I'll be waiting for the ocean modifer thanks
@@suryakamalnd9888 Why not. But,the larger domain you have,the higher resolution you need to have.Also very long time to bake based on ur com specs.
@@GraphicsMK ohh.. so theoretically if I had a nasa pc that would be possible.. well mabe if Pixar wants they could create it.. anyway I'll recreate this tiny version only.. and ya bro seeing this I got a idea.. is there a way to make a 3D model boat react to this water? My idea is I'll setup a seen with this, I'll render it and using the ocean modifer, I'll setup a huge seen and I'll combine both.. the little part with focus will be this and the baground will be ocean modifer.. this seen is a plane focused seen... The boat will be seen for a split second and the camera will shift towards a plane flying above.. hopefully it will be epic
how do i simulate a fluid in an enclosed space? like a Potions bottle or something ?
I'm not quite the world class guru on Blender Fluid Sim, but I was working on an animation involving that. Make a mesh shaped like the bottle. Make a domain cube enclosing the bottle. The bottle gets a Fluid sim set to Effector. Put a sphere or cube inside set to Flow, Geometry. I'm too lazy to try to make the fluid fit the container, so just a sphere or cube. I set whatever params I like, turn on the Mesh checkbox, and bake 100 - 200 frames. Use the mesh from the final scene as the initial fluid for the real animation. In my case, I want the bottle to tip over and roll. It's not clear to me if that should work, since I keep screwing up simpler things about animating fluids. Good luck!
How would I animate a faucet or hose or drain spout spilling out water for a limited duration? Or have the flow increase slowly over time? It's not obvious which value to animate.
Hi. I have another tutorial about how to animate a faucet. I explained these topics there in detail. th-cam.com/video/pukCAUZu15M/w-d-xo.html
Still new to Bl;ender, have been using it for a while though and I've done some fluid sims before but never in a project, how do you keep the domain from being visible in the scene? For instance, I got the sim to work everything looks good, but then when I render you see the domain until the sim kicks in, the domain goes away and the sim plays, when it's done the domain comes back. if I make the domain big enough to encompass my scene, even if I apply the scale I now don't get any fluids to simulate, could it be because I am scaling the domain big enough to fit my whole scene that my particles are there but a lot smaller than original because of the up scaling of the domain?
Hello.Before rendering pls check your timeline and fluid baking start and end frames are the same.If you scale up ur domain so much,ur voxel (resolution cube ) will become larger.If the voxel size larger than ur flow object,then fluid simulation won't work. In this case,you need to increase resolution division value.
@@GraphicsMK interesting I had a feeling something like that was going on, I'm running low on time for my submission, just gonna forgo the blood squirt for now and focus on the details I can control. But thanks for the info, I'll play around with it after I'm done this render. I just love learning new stuff, and then playing with it until it breaks, then figuring it out how to fix it, it's my convoluted way of letting lol appreciate the help MK!
Sir, thanks for the video In the animation I made, only Liquid is on, but the particle rendering is also visible. How can I fix this situation and make the particles not visible?
Click on the particle properties tab, and disable the camera icon. So , ur particles will be unvisible in render result.
Hello how are you? When I do fluid simulation, in the wireframe view everything is fine... But in the other 3 views the cube appears, what could be wrong?
Thx you. I hope u are fine too. Most probably you didn't enable the mesh option. So, you only display the domain cube in other views.
Hello author, you explained it very well and I really like it🥰🥰. However, in Blender 3.6, the domain guidance function does not work according to your method of operation. Can you share the tutorial files for this issue? I would like to see the details of your operation. Thank you❤❤
Thank u. Yes , as u said domain guidance function doesnt work. I tried to find a solving but I didnt find yet.
@@GraphicsMK It's okay, I'm looking for a solution too, let's cheer together
@@GraphicsMK Hello author, about this problem I have solved in blender 4.1, and have sent the solution to your mailbox, but the effect is not perfect
@@nicon4658 ok thank you for sharing. I will review when I am available.
How his 64 domain subdiv looks 2x better than mine?? I only get that smoothiness from 128 subdiv or above
hi MK I have a problem in the example paragraph 23:28 to 26:15 I did exactly as instructed but in the end I only see smoke but no water but when I don't select "guides" the water appears again, I am using blender 3.4. hope you can help me thank you very much.
Yes as you said I got the same problem in Blender 3.5. I will work on this problem. If I find a solution, I will share.
@@GraphicsMK Thank you! I am looking forward to the latest video from you.
@@GraphicsMK any solucion? really helpful tutorial, thank you so much
baking takes so long for like like 30 minutes and i have resolution set to 24 am i doing something wrong or is my computer just not made for this
hi, i have a question about the visibility of the liquid domain. i start animating the liquid on the middle frame (90th frame until say 120)
the domain appeared in the 89 under frames and after 121th frame. is there a way to get rid of the visible domain outside the animation time.. thanks before
Yes. Go to outliner menu,disable or enable the visibility of the domain object in render result. You need to animate this property.
@@GraphicsMK thanks for the kind reply. i will look to it.
@@GraphicsMK it works i just plug a mix shader on the texture to switch to transparency and cue animation according to start frame.
How do you create a peaceful water surface from the start with the fluid simulation? I mean without it shooting particles from the beginning? Thx alot
Just create a domain.Then add a cube object inside the domain.Just scale down the cube little bit so that almost touch the side faces.Scale down the cube on the Z axis.And add geometry flow for the cube.That's it.
@@GraphicsMK thank u sir
@@GraphicsMK Is it possible for you to make a wave tutorial? It seems every wave videos on YT are made by Flip Fliuds, I tried to make it with manta flow but it just didn't work and I don't know where the problem is
@@GraphicsMK I mean, like ocean waves which you make soemthing to push the water underneath it
where can i get the folder?
Thank you for your sharing. I followed the settings in the "Guide" part, but it didn't work for me. I used the same settings but can't find the reason."😮💨
In the new versions of the Blender, It didnt work for me also. I will share if I find a a way.
Thank you very mush. 🍻@@GraphicsMK
It's better to include all these parameter effect into a complete showcase that we can follow. Cuz we just have no motivation to just play around with these parameters.
when I turn on guides in fluid simulation and choose gas domain as guide parent. The fluid wont bake. It only shows gas after bake. Can you please give me a solution for this or guide me if I am doing anything wrong
Unfortunately, I couldn't find any solution for it in the new version of Blender.
Please moooooooore
4:07 followed every step but no liquid is coming out :(
i have the same issue
I had the same problem. After I activated the "Is Resumable" option in cache setting under type, the particles showed. I deactivated the option right afterwards and it worked. Maybe a bug?
Could you please tell me your computer specs?🙏
Intel(R) Xeon(R) CPU E5-2678 v3 2.50GHz, GTX 1050 Ti Graphic Card . Unfortunately I dont have top level hardware.
@@GraphicsMK Thank you very much. Now I'm looking for a computer. I just want a computer that is suitable for 3D work.☺️
How to make the simulation settle down, how to reduce the energy of the fluid simulation, after stoping flow water calms down, but keeps moving and oscillating to infinity.
I haven't seen that yet, despite my unintentional creativity in messing up fluid sims. More simulator pathology to look forward to! Wild oscillations and shooting off to infinity are often symptoms of loo large time steps. I know from writing and running physics simulations. Not Blender physics, I mean real physics.
Are you making an animation at 24fps? Did you turn up the gravity or mess with the Time Scale?
If not, my first experiment would be to crank up the Timesteps Maximum, from the default of 4 (?) to something like 10. That will render too slow for producing a feature film, but I'd run the sim at least as far as the point in time where things were going wild. If the problem appears to be solved, you could nudge it back down from 10 to maybe 7 or 6, and find other settings to adjust to improve the simulation.
Did you crank up Sampling to more than the default of 1? If so, the next thing to try, and this was happening for me earlier today, the setting under Liquid, Particles Maximum defaults to 16, and Minimum is 8. I was using these with Sampling set to 5. My model looked good at frame 158 but frame 159 had particles all over the domain and all red not blues and greens. I cranked up the Maximum to 33 (too lazy to move my finger over to the '2') and the Minimum to 1. The wild shooting-off particles then behaved nicely. It all has to do with the math of how these kinds of simulators work, how much simulated material can be in one small space at a time.
Particle Radius is usually worth nudging up or down a little. From the default of 1, adjust to 0.8 or 1.2 and try again.
Every time I use Fluid Simulation, I discover new ways to make mistakes, and I am from from done with this learning adventure!
@@DrunkenUFOPilot Tried all of the suggested things, still the same, water just keeps moving, i have a 5 second fill up simulation after 5 - 20 seconds more, water becomes calmer and has to setlle down, but it doesn't calm down eaven after minute, it keeps all the motion energy as you would look at the infinete sea shore motion.
@@migloje Viscosity? Even a little, 0.002, might help.
@@DrunkenUFOPilot tried this not working for me. I spend few weeks on just one purpose to make water go still tried a lot of parameter changes. I just don't understand where the excess energy come from, water gets almost still and then starts oscillating and wavy again. Even if i turn viscosity to become honey like the oscillations won't go away, no gravity or other parameters will effect the osculation.
th-cam.com/video/-OqPLHwVfO4/w-d-xo.html
I made a short primitive video to show the oscillation problem, other setting as viscosity time steps dont make alot of diference to the osccilation, energy somehow wont go away.
