Thanks for your detail examples, it makes following the tutorial very easy.
thank you for making this look so simple!
this is so cool !
i like your tutorial ! thank you！
You are just amazing 👍 the best tutor on the whole Internet - Can you do a tutorial for simulating ink in water?
Very interesting results; I was wondering if you can create another tutorial showing how to apply the Rayleigh-Taylor Instability into a 3D volume.
Thanks a lot for the tutorial! This is a real help!
I was wondering if you could help to figure out the environment for Lava Lamp? I am pretty new to Houdini and tried to build a Lava Lamp only in Flip solver and researched a lot but never got an acceptable result.
Maybe some advice about the direction of how that could be done?
Or any thoughts about that heat attribute to influence the behavior of the particles.
I would really appreciate any help.
Thanks again!
very interesting result !! You can get a lot of detail ignoring 1 dimension... Do you think I could simulate a thin layer on the surface of a sphere? like a planet, constraining them to the surface. To then assign different colors and properties in layers
The final video reminded me of the album cover from a moon shaped pool
for anyone trying this: don't mess with the particle radius scale. I though lowering it would make for a nicer looking sim but it actually made all the particles fall to their doom as if closed boundaries was never enabled
how to make the particles run in a circle ?
Is there a way to export the video of the final product to a video playing software? thank you!
how can i easy change the shape of the box to an extruded curve? i thing somewhere in the flip solver?
Cool tutorial! How can I render this in octane? I'm new to Houdini.
I really want to get the final render you show in your tutorials, can you either make a tutorial or share the scene file with render settings please?
HI this is a great tutorial
I tried to apply this effect to an image I have
by applying density for tow separate groups like you did
but I do not want to change the colors of my points in image I want to keep the Cd value of the points
it didn't work with me can you please tell me what I did mistake
Is there anyway to do this on a sphere instead of a plane for example?
Thanks for nice tutorials:)
How can I make these points slow down? Not the shape, but only speed of particles.
I changed 'viscosicity' value, the shape of flow is changed.
Heyhey,
try attaching a timewarp-node to the end of your node tree, set it's evaluation mode to "by speed" and dial in how much you'd like your simulation to be slowed down. Also manipulating your dopnet's "scale time" parameter on it's "simulation" tab might be an option.
Cheers, Mo
@@Entagma Thanks, I was following the tutorial and I noticed that my simulation is too fast, I thought you might put a comment or a reply to this issue in comments and here I found it, using time warp-node destroyed the simulation, you get some very ugly artifacts, but scale time in flip solver with a value of 0.4 actually solved the issue.
trying this with an image, but get's stuck after the first frame any idea what could be happening?
Nice work 👍. Question can this be exported to ".AbC" or other format to use in c4d as I have third part render engines there . I'm new to the Houdini world thanks for the help
Did you find the solution? I am trying to do this too.
@@ayushsaud they also made a tutorial how to export to alymbic format. They show to how to convert the points.
@@JamalPennant Thank you very much!!
@@JamalPennant Please share the link to this video. Thank you.

I've been trying to do this on a regular windows computer for many weeks now and it doesn't work - granted I have included viscosity in the VEX code. Anyone else having issues using a regular computer?
Hey Stepehen,
been using regular Windows computers since 1994 and constantly having issues. Also tried Linux and MacOS for a few months/years. I think it's computers in general and not the OS :D
Cheers, Mo
@@Entagma Thank you for getting back to me! I really appreciate it! Have you found certain computers that work best? Which one are you using in this video? Everything moves really fast, mine takes forever just to do some of the smaller operations you do. Thank you again!
what computer are you using?
