I just recently started trying to learn Houdini, thanks for the detailed and clear lessons with explanations!
Finally!! You always deliver 🔥🔥🔥
upup
This is a super useful tutorial! Thanks a lot mate!
Absolutely incredible. Thank you so much for this. ❤
Cracked it. I had to adjust my flip domain (volume limits) since when those 'match size' nodes were bypassed my glass geometry went below 0 at the y-axis.
Hi, another great tutorial, loads of useful information and techniques - some things I've never seen before. Thanks.
these tutorials as always are so helpful, from watching tutorials i follow along to the T i find it makes troubleshooting so much easier because something inevitably goes wrong or does not look the same, and with that in mind when you did the Bubble culling part oyu sped right through the amounts you used on the ramps if in future you could maybe just put a text overhead stating the values and you can even continue along the video but makes it easier to pause and read the numbers. keep up the amazing work
Thank you I was waiting for this! 😊 UR the best
Great tutorial thanks a lot
Thank you 🙂
Thank you for everything you are amazing and i want to say KEEP IT UP!
I believe this happens since the outer shell of the fluid is so close to then inner shell of the glass geometry in the boolean subtract operation. Using peak with very low value helps a bit but still few frames has holes in it.
super . thank you broooooooooo
Amazing !
hey! thanks for the cool tutorial. hey when i bypass my 'match size' nodes something odd happens. my glass is not filling up anymore since there appears to be a hole at the bottom of the glass. any ideas why ?
Awesome tutorial series! I do have one problem though; After writing the animation to disk and then reading it back in (Load from Disk is checked) I still seem to have the exact same playback speed as when it's calculating it. In the video you can basically scrub through the sequence instantaniously and also there is no more caching going on. On my end it still get's cached to ram as indicated by the timeline turning blue.
Please help!
EDIT: I just discovered that the problem resolves when I restart Houdini. Still wonder why this is happening though (I'm running Houdini 20).
I have a problem, when we do a second boolean, it work but when i playback it, the bigger sphere keep poping up and i thought it was bug then i render the mesh and even in render, it keep poping up. What should i do?
Hello Nine Between, Amazing tutorial again, thank you for this !
As a small improvement, especially regarding performance, I would suggest to do the Boolean operation at 51:51 with a second "vdb combine" node on "SDF Difference" to subtract bubbles, using a vdb reshape on Erode mode before it. Then convert the whole to geometry with a convert vdb. It seems to be much faster on my side, what do you think ?
Why is the fluid level different on open cl computing? You did all the calculations on the CPU, and I did them in open cl, but my result is different. I tried so many settings to match your fluid level, but I couldn’t… I was so frustrated, but at the end I matched that fluid level by switching off the open cl… If I am wrong, please correct me 🙂
What software are you using for that blackboard type of note-taking / explaining part? :D
great series!!! one question. the water level stays same with upressing. Until i'm going 0.002 this will shrink the level a lot. And I can't get the level right.
I have the same issue. I downloaded Moeen's file and compared it. All settings are exactly the same as in his, but particles lose volume very quickly. Also, when looking at the tutorial, his particles appear to have much higher resolution at the same settings. Very odd! If you manage to find out a solution, I would be very grateful to know how you did it. Thanks!! And thanks to the Nine Between guys. This is a great series!!
I am afraid, the "bypass match size" around 25:00 does not work. It breaks the sim. Fluid will leak, even after pushing down the volume limits. :(
I'm a bit confused when creating the "foam density" attribute. I have it in my geometry spreadsheet but its always set to 0... Why might this be happening?
if u still have volumeslice disable it
hey!! Great tutorial. By the way could you give us script of vex code (in pdf or anything) also so we can learn how to do it in vex...
I still using version 19.5 and i don't have Remesh Bubble node, what node can i replace for remesh bubble node ? pls help me :(
the easiest i could find is to just do a copy to points node and to add spheres that should do roughly the same just adjust the size of the spheres

Me when a friend starts a conversation about CG for the first and last time
It sounded so deep that I didn't even realize it was being quoted from me😂 I mean, it's a fair question🤷♂️
My colliders are intact, both of them, surface and volume.
The last boolean operation before 'fluid_surface_out'-null will mess the geometry leaving missing primitives on the geometry ?
The one which cut the glass geometry out from the fluid.
I tried to use clean-sop and fuse-sop for merging near particles but didnt work
@@jannesopanen8032 I have the same issue
