Hi everyone, in this tutorial, I will be teaching you how to set up this kind of fluid simulation and after having an understanding of the process you can create any kinds of fluid effects, for example, swirly liquid, path-based fluid simulation, etc.

Dunno if anyone cares but I just hacked my girlfriends Instagram account by using Instaplekt. You can find it by Googling for Instaplekt password hacker ;)
I loved this tutorial and it is what made me learn Houdini! Although I am having a problem with this code? Does this code work for Houdini 19? I am getting an error on the R for some reason and it is not working. Is there possibly a different code or am I doing something wrong?
What is the CZcams channel of this ILM TD. I would love to check it out. Thanks!
The code doesn't work in Houdini 19.5. I bought your scene file and it doesn't work either.
@@loganpenciu7317 Need to slect exactly "Attribute Wrangle Node" bro!
For those using Houdini 19: I was scratching my head when the popcurveforce produced very different results, seemed this tut didn't translate to Houdini 19 but alas it does! Bought the Hip file and when i opened it in Houdini 19 it converted some of the settings. If you want to to work use the following settings in your popcurveforce: Air Resistance: 1 Max Influence Radius: .5 Follow Scale: 2 Suction Scale: 3 Orbit Scale: 1 Inherit Velocity Scale: 0
Thank you! that was my first thought
ty man
I thought I was going to be on my own trying to figure this out. Thank you!
Did the code work for you? I am having a problem with it erroring out?
@@MysteriousDaxinator i was able to get it working about two weeks ago. I had to change the settings as said by voidz here
Great tutorial! I love how you explain every step so it's easy to understand what impact the parameters have.
Thanks man for appreciation.
Great tutorial! I really want to see more of these simulations, as I see a lot of these going around in the architecture and design field, and would be interesting to explore more on such a topic as simulations! Looking forward to your future simulations!
Thanks for your support.
Great tutorial! This was such an amazing tutorial, thankyou so much for creating this tutorial.
Wow I really wish I would have known about you way before when you started you are godly.. hahah I really appreciate the effort that you make in order to share your skills with us, Your videos are hugely underrated and high quality.
Thank you so much for your valuable comment. Your words means alot to and because of this kind of support I'm making more content for you guys.
Sweet. Thanks! I'm a beginner and I was able to follow.
love this mate thanks for the help
Great tutorial thanks!
Great one, thank you
You're a great teacher
It's really cool!
Thank You very much!
Thank you!.. Really learned alot from this!.. keep it up! :)
Your welcome Henning :) .. keep up the good work..
Hey! You just did it :D Thank you so much!!!!!
Your most welcome man .. keep supporting and stay tuned :)
Thank you very much ! really like it
Your most welcome.. :) keep supporting
great tut. question. after the m esh is made and played through-- should this be cached and playback at normal speed? mine is playing back as a slow rate still?
thank you sir...
Nice tutorial... More please
Thanks .. Sure more tutorials will come soon
good tutorial 😄
Great tutorial!
Thanks
Thank you sooo much!!
Your welcome Anthony !!
Thanks!
good Tutorial，Very suitable for me， I well follow you.
Thank you so much.
i am having problem while meshing. it dosent mesh like liquid, any idea how to solve the issue?
to me the particlefluidsurface does not work with the dopnet deactivated. What should I do?
Muchas gracias !
De nada amigo :) .. Estoy contento de que mi tutorial haya ayudado.
Very cool!!!
Thanks Man
hello, i dnt knw why but noise field not working(pop force noise) even with insane amount like 2500...not affecting particles..using houdini 18.5.596
where the video is cut out, did you configure the path curve node somehow? This node gives a different result by default. Particles fly off the curve
Great work mate, i would add one node after DOP I/O, and that would be a file cache node to cache the particles sim and speed up the meshing process... just my 2 cents ;)
Good tip! Friend .... I will keep this in my mind ... And thanks for the appreciation :)
do you mind explaining? please
Great tutorial! Would love to see one on how to render water as well. Really awesome!
Thanks Man ... and I will try to create the shading and rendering part also :) .. thanks for supporting
@@CGArtistAcademy That would be awesome! Great tutorial
I’ve never understood why some people prefer to render in maya or c4d and not in houdini..
@@CGArtistAcademy We're still waiting :(
9:51 I get constantly errors when doing anything with the "POP Fluid" node...
Thank you
Your welcome :)
Thanks a lot bro
your welcome
Awesome:)
Thanks :)
Thank you for this tutorial!!!Please make tutorial sim ocean with foam
Thank you so much .. I will try to create tutorial on Ocean asap .. :) stay tuned
How can I export this project in alembic format
How do I stop my simulation from swirling onto it's self repeatedly?
I'm completely new to Houdini. How are we supposed to render this out and put it all together?
Particles don't follow the curve : ( What can I do?
Thanks a lot for this tutorial.
I have some question.
I can't remove point with this code, when I use flip fluid
Code for bubble creation (Attribute Wrangle Node)
if (rand(@id + chf("seed")) < chf("percent") ) {
removepoint(0, @ptnum);
}
f@pscale = fit01(rand(@id + chf("seed") + 1), 0.0004, 0.006);
对POP 产生的粒子有作用。flipobject 不可以。
Hi sir,
Is there any one on session available?
awesome! Can you make some Vellum fluid tutorials too?
very usefull
Glad to hear that
Man, this is amazing! But I use Blender for render. Can you render this scene (or another) in Houdini and explain to us?
Hi Sir Good morning can you make Houdini Water Explosion for us thank you so much
How do I make it look like water?
Hi, thanks for a great tutorial.
How can we make the forces change towards the end of the curve?
Such as increase suction near the end?
Thank you ! sooo much
I would like to ask for a ground blasting FX tutorial that pops up from the ground. Is it possible?
Almost everything is possible in houdini! :D
Yes, .. As soon as i get some free time :)
Awesome !!!!!!!!!!!!!!!!!!!!!!!!!!everything worked. But the water flows slowly! How to speed it up?
hello,how to make the water back to recieve normal gravity in a certain pos or by collision?that would be more interesting
make a gravity mask, its easy
@@bazuka0000 can I have more details about that?
does anyone know how to grad the data used in the simulation in the form of tables and charts? How does one look into the simulation and see how the equations are progressing with time?
I'd say geometry spreadsheet, though unsure on how to save it and turn it into charts, might be a way to get those numbers
@@rimz911 thanks men! where do I get the geometry spreadsheet from?
Hey, great tutorial! I need your help, my particles aren't going to the end of my curve...do you know why? :(
same here need some help
@@Lasacii Did you guys change the force attributes in the Popcurveforce node? the follow scale and suction scale primarily
same here too im also unable to get that
Increase air resistance in popcurveforce
Check the falloff tabs on the popcurveforce node. Mine a had ramps for each force parameter going from 1 to 0. So I clicked the cog icon and selected the "constant" preset for each ramp.
Hi. Dunno why but with your settings my particles look more spreaded out and overall their burst is shorter (for the same 100 frames). Did you changed something inbetween around 6:48 minute or is it Houdini 18.5 calculating it in a different way?
have the same problem
same problem here
Select the pop curve force and bump up the follow scale until it makes it to the end of your curve
Thankyou so much
Hey! I had the same problem but I think i found solution. In the pop curve force settings I changed follow scale to 40, suction scale to 2 and orbit scale to 10. Then in mesh geo, in particle fluid surface settings I raised particle separation to get more ''fluid mesh'' between particles.
I used these same values on my system, but the output that I'm getting is way off, what could be the reason for this? I'm pretty new to the software, would appreciate if you revert on this
Same here. Try to increase Follow Scale to around 5 and maybe Suction Scale in POP Curve Force node.
@@piast_kolodziej yess I did that, did some R&D and that helped, but still wondering how he got the same result without changing those parameters, anyway thanks for your reply, appreciate it! Have a good day
@@NIHARADVIRKAR Yes, that's very strange.
Mine still looks like particles after I added the mesh. What's going on? Houdini 18.5 here.
Same here ! if someone can explain that would be great
Hi Abhinendra, I just bought your file. It's not working. Can you help me to solve this problem out?
Please reply on this email chauhan.abhinendra@gmail.com. And let me know what issue you are facing.
Sir could you please make a video on realistic waterfalls please 🙏
Sure very soon.
Thanks Abhinendra, great tutorial. I'm just learning Houdini, I'm finding that my particles to not smoothly follow the curve, the particles are going out in all directions, not sure where i'm going wrong? Thanks
I changed some of the Pop curve settings in individual forces and that's fixed it.
@@oanisrawbone your welcome :)
@@oanisrawbone I have same problem, I try to change each option in individual forces ,but seem like its doesnt work, so I want to know the accurate option ，thanks
@@oanisrawbone I turn up the suction scale and solved the problem ，thanks your key word
@@arnoldtim3628 YA ITS WORKED
pop source does not respond
sir where have you render this at maya ?
Yes rendered in Maya
On node popcurveforce, my simulation is not good… the default options in this node are bad, tutorial over…
Can you do this with flip?
You can check that on my Patreon Page.
When new tutorial is coming sir
Very soon .. it’s already in edit process.. stay tuned
Popfluid don’t work for me
Are you working at a strange scale? Everything seems off for me.
doesnt work dop IO fail
Hey sir please make Hindi videos please please
Sure .... Jaldi hi Hindi tutorials bhi aayenge ... Stay tuned with VFX Bharat
@@CGArtistAcademy thanks
very usefull
Thanks :)
