It took me like 3 days to figure out most of the stuff that was mentioned in this video. While there's no official documentation on the manual about how to troubleshoot the issues, this video will save you a lot of time. Great stuff, thanks for this!
can you run by me if you can how to water sim a cube falling down steps with water splashing inside? you touched briefly on it......ASAP PLEASE.....AYOUR WORK IS wonderfully inspiring.....
This is awesome! man. I have been scratching my head for days trying to figure out why my fluid will not flow through the pipe. I watched this video about fixing the normals and try it. Guess what, boooom....it worked great. Thanks for taking the time to make this tutorial.
Thank you for this video. I watched several videos before this one, and none of them is as simple to understand and straight to the point like this one. Thanks!!!
You are my hero. I would never have thought to turn the normals inside out and then change the thickness! So grateful you took the time to make this video!
My Fluid simulations never work, I add a uv sphere then then select fluid, then change the settings to liquid and inflow and domain resolution to 64. pretty much the same setting you use and see no particles when i bake data. this happens everytime
I'm using the fluid simulator in Blender 4 and this video solved all my problems with dispersing particles. Despite the posting date, this tutorial remains current and functional. Thank you very much.
omg I was having a weird issue with a tube leaking fluid and nothing would fix it, but your fix of increasing the surface thickness solved it immediately! THANK YOU SO MUCH!!
At 1:00 Select "Is Planar" option for planes ( I believe this option is for planes cuz when i selected this option, it worked well) It works for cylinder or cube which has no thickness
Oh my god, this was sooo helpful I struggled for the last 3 hours trying to fix my simulation when I would have just needed to turn up the Substeps! THANK YOU!!!
So fun, I was attending your Udemy Mantaflow course, paused to make a google search, found this video. Then I started the course again and you explained the same :D Your course at Udemy is amazing, thanks !
all day trying to figure out why simulation wasn't playing and when i tried it outside the room finally it worked so after watching this vid I realized the room i was trying to play the simulation in had the normals on the outside and sim wouldn't even start. Huge help thank you
If you have encountered any other problems that I did not discuss in this video reply to this comment and I will try to help out! Edit: If you do not see the bake button that is because in the Cache panel the Type is set to Replay. Set the type to Modular and you will see the button. Also sorry for the low framerate. I forgot to set up my recording properly! Whoops. Next tutorial will be back up to 60fps!
I think that is a bug at the moment. I heard somewhere that it shouldn't be like that. CG Geek had a great method for getting rid of that grid pattern that you should definitely watch!
Thank you! 👍🏼 It did not fix my problem but at least now I know where it comes from. Another thing to mention for fluid sims with mantaflow: I never got a proper result when I tried to use real life sizes. I had to make a 60 cm wide cup to be able to 'splash' the fluid in a realistic looking way.
Hi, as many people down here in the comments I was so much lost in fluid simulations errors. I watched a lot of tutorials, but they never explain thoses kind of stuff. So I would like to great you for this great video ! As the name of your channel, thanks to you it's really easier now !
You rock!!! I was so stuck and didn't realize that I needed to bake the data in order to see the fluid flow! Also thanks for the advice on increasing the surface thickness - who knew?!
Thank you so much, this was great, just what I needed for one of my fire-smoke explosion that was not working and I couldn't figure it out.. now it is working just fine.
Thank you for making this video, other youtubers that are most popular, dont even mention this stuffs, that it seem are crucial for making simulations. Valuables stuff !
Very nicely laid out! I would argue that bringing up the surface thickness is not always a nice way to go as it makes the fluid not touch your collision object anymore, but your explanation is very helpful to understand glitchy behaviour. :) More often than not I think it comes down to creating realistic objects (nothing in our world is 2D after all) and bringing up timesteps as you mentioned.
Such a great video! I was looking everywhere for an updated tutorial on how to keep fluid inside an object, and it was just by chance I saw that you addressed that in this video! Thank you! :)
hello i tried the tutorial and it was going well and all, i baked it too and it was looking fine but then i had to shut down blender and open it again and animation wasnt there...no water animation nothing onlu cube and circles... could you help me with this problem i dont know what to do...
Most useful video ever! You answered the questions in my mind :) Blender crashes during baking. I wish you talk about this in the next videos. Thanks again for this tutorial. You're great
When the inflow objact was too small compared to the domain sth that usually fixed it for me was too turn up the resolution of th simulation. Thank you for the great video it truly is a big help.
Hello, thank you for this video! I am having problems creating a fluid sim running through a pipe where the liquid seems to hover above the surface of the inside of my pipe. Even with no surface thickness it seems to hover over it :( I've tried everything you've suggested in this video and more!
@@razz6539 Hmmm, that was a long time ago but if I remember correctly pumping up the resolution size helps create smaller fluid particles. But of course that increases bake times. I would suggest getting Flip Fluids if you can afford it, I have been using it since and it is much better but it is pricey.
experimenting with blender. been using Maya since V1 (for my job) and Fusion for fun. also an old after effects guy. Problem with blender and learning is that they change so much with every iteration people get confused by watching tutorials online. example, it looks like they already changed 9:23 for the "bake all" part, from "type:final" to "type "all".. not sure why they would change something like this, when "final" made perfect sense. not entirely blenders fault, its just that people are following older (and by older I mean maybe months ago) tuts that are outdated and not working. this program is SERIOUSLY trial by fire. I've spent so much time doing tutorials over and over and over just trying to get a result. its a bit overwhelming. When I first started using fusion it was predictable and results were the same every time. they barely changed up the important things (UI and UX stuff) and it gave some continuity to learning.
Fabulous video for beginners.. really very very helpful.. I still have one problem though.. when I simulate fluid, between the effector and fluid, there is a small gap. how can I remove it so that the fluid gets touching the borders of the effector. Thanks in advance
cut a hole in the top of the sphere at 5:10 please and show how to get it to work because i am working with potions bottles and the fluid ignores them even with inverted normals
After 3 years of problems with fluid simulations in Blender, i thought this video was the solution and... it still doesn't work. Thanks for false hope.
Fantastic man, thanks. However, how can I create a liquid simulation that begins with a container already full of liquid? Rather than beginning with the simulation of filling it up
Hello! Awesome video, very informative. I have create a fluid simulation where my camera is located outside the fluid domain. When rendered, the domain appears opague and blocks the camera from seeing anything inside the domain. Am i missing something? Thanks alot !
Thank you so much for this video, it’s very helpful! Although I do wish I found it a couple of hours ago when I was debugging what was wrong with my simulation
When I use smoke noise the noise will phase through objects. It's not like the old way where it kind of subdivides the smoke making it a higher resolution.
If the domain size us huge like a real life room size and the inflow is small. What setting would you need to tweak to make that fill a room? My kitchen scene...the fluid starts to over flow the sink but stops once it dripples over the edge and doesn't continue when touching the floor. I have all objects set to effector and as planar too. Is there a setting that tells it to spread out more?
That was my main problem too. You could select search (f3) and type 'Bake' which offers a 'Bake All' option, or it could be that your Cache Type is set to Replay. Try changing it to Modular - the Bake option then appears. My other problem is that no flow appears when I bake!
I'm not seeing a "Bake" button in my Fluid pane. Everything else is the same as on your screen, except there is no Bake button, but there is a checkbox for "Delete In Obstacle", which doesn't seem to appear on your screen. This is driving me crazy!
Hi, I have a question, maybe I didn't noticed before, but my issues is like at 1:05 when filling up the volume liquid go up, like only the surface will be show, while the "filling" doesn't is that normal? I use Blender 3.0.1
![Fill any Object with Fluid in Blender [Mantaflow] | English](/img/1.gif)
It took me like 3 days to figure out most of the stuff that was mentioned in this video.
While there's no official documentation on the manual about how to troubleshoot the issues, this video will save you a lot of time.
Great stuff, thanks for this!
why is the bake button not on my settings. ITS REALLY ANNOYING ME!
PLZ HELP!
can you run by me if you can how to water sim a cube falling down steps with water splashing inside?
you touched briefly on it......ASAP PLEASE.....AYOUR WORK IS wonderfully inspiring.....
TheModulator Hey switch from replay to modular and go to cache section of the domain and select an EMPTY folder..
Took me 3 hrs before I actually gave up and went to youtube
@@kruddystupididiot Select Domain, then
Select type, then change the option from replay to modular or All (blender 2.91.0 )
This is awesome! man. I have been scratching my head for days trying to figure out why my fluid will not flow through the pipe. I watched this video about fixing the normals and try it. Guess what, boooom....it worked great. Thanks for taking the time to make this tutorial.

you also need to change setting in domain and flow. Otherwise just select the uv sphere and then in object tab or search quick fluid that will work
Same here. No matter what I try even the simple sim setups don't work in Blender, just not worth the time anymore :(
make the sphere bigger and try again

Thank you! I couldn't figure out why my fluid was passing through the mesh, turns out the timesteps were the problem.
Glad I could help!
Thanks a lot maaan. I actually learned a lot, when u explained the most commont mistakes anybody could run into.
This is perhaps the most helpful mantaflow video I've seen posted on the web. THANK YOU!!!!!!!!!
Glad it was helpful!
Thank you, this made my day! Didn't find a solution for days and increasing the surface thickness resolved it :)
that was awesome. I was about to start bashing head against desk.
Hours watching a lot of videos without my currents problems and you made it easy!! Thanks a lot!!

How about the grid pattern in the particles like spray, foam and bubbles. How to solve it?

Holy crap thank you so much. Your are the only channel I found explaining this well thank you so much I really appreciate it.
Why didn't you mention the "Is Planar" checkbox when you talked about meshes that don't have a volume/are flat
Can you explain please?
I was wondering that, too.
hello i tried the tutorial and it was going well and all, i baked it too and it was looking fine but then i had to shut down blender and open it again and animation wasnt there...no water animation nothing onlu cube and circles... could you help me with this problem i dont know what to do...
Finally I was saved! Thank you so much - I was lost in so many tutorials…
Thankyou brother. This video cleared all problems that i was facing in Mantaflow. Thankyou so much ❤️
Hey, at 7:00 you can see that the fluid doesn’t touch the solid… how do you fix that ? Thanks 😋
Thx! I was trying to make a river and I didn't know how to make an obstacole for the water. Thank u very much!!!!!
Most useful video ever! You answered the questions in my mind :) Blender crashes during baking. I wish you talk about this in the next videos. Thanks again for this tutorial. You're great

Your video appeared like a life saver for me..... Thank you❤❤❤
really thanks man really thanks you solved my all problems if you dont here i will not do mantaflow simulation. Thanks.
You awesome man, it helped so much to understand better the functionality and bugs of these simulations
Thousand of thanks !! you give answers for common problems in blendering simulation 👍👍
@Blender Made Easy thanks a lot. Trying to make a text a domain to fuel with liquid and didn’t show the particles. Will try this settings! Thank you!

Never been baking so musch as now! Seems to be a problem with the simulation a lot. This video is great help. But still a lot of problems.
Brilliant! Addressed a lot of collision issues I had been having problems with. Thanks 😀
Could you go over how to setup everything for render view? smoke and other similar particle effects don't show up in render view but work for others.
Thank you for such detailed explanation of all this problems and their solutions. This is really helpfull !

You are so right. Finding the right tutorials is really time consuming with blender because of all these videos of older versions on youtube.
Thank you so much! I was having so many issues with mantaflow and this solved all of them!
Love you man...
You just solved tons of my problems
This video is so awesome
Magnificent video. This is a keeper
Really nice compilation. Thanks alot!
Thanks, this is great and the timesteps tip helps a lot.
This video is SO informative. Thank you!
Thank you very much, my fluid didn't work. Now it works !!! I thought it was a Blender 2.83 bug.
Fabulous video for beginners.. really very very helpful.. I still have one problem though.. when I simulate fluid, between the effector and fluid, there is a small gap. how can I remove it so that the fluid gets touching the borders of the effector. Thanks in advance
bro, this video is a GODSEND
Thank youu 🙏🙏🙏
Thanks for sharing! Do you know if its posible to create a vacuum or suction in blender? I'm looking for but without good results :/
cut a hole in the top of the sphere at 5:10 please and show how to get it to work

I don't have a bake button! Is there a setting I am missing?
Thank you so much. It really helped me!
Really informative man thanks!!
This was terrific! Thanks
took 1 week for me to find this video, thought my computer didnt support lol, thanks a lot man ;D
So useful! This is exactly what I was looking for and helped with my problems. Gold video!
Fantastic man, thanks.
However, how can I create a liquid simulation that begins with a container already full of liquid? Rather than beginning with the simulation of filling it up
Actually Helped a lot❤ keep up the good work❣
At 5:54 you can turn the tickness of the object to 1. the more you increase it the less problem you'll have with particles spilling out.
huge help and relief. thanks!
Hello! Awesome video, very informative. I have create a fluid simulation where my camera is located outside the fluid domain. When rendered, the domain appears opague and blocks the camera from seeing anything inside the domain. Am i missing something? Thanks alot !
Is fun to see how u solve all those problems, It would be even better if that solutions were enough to fix my simluation problems
Your video is great! love to see this!
is it possible with the new features to have two different fluids interacting?
Thank you so much for this video, it’s very helpful! Although I do wish I found it a couple of hours ago when I was debugging what was wrong with my simulation
I’ve been trying to learn blender from scratch and this video is extremely helpful
