To whoever have doubts about the cache like me, if you are using 'explicit path' instead of 'constructed' in the file cache node, you need to replace $F with $FF or $T in order to write the substeps correctly. I would use $FF in 'constructed' path just in case too. You can see more info by hovering the cursor in the 'substeps' option in the file cache node.
He didn't cover all aspects, he skipped over how to cache the sim and went straight to importing the cache files. I'm confused now how to create the cache.
Hello! really nice tutorial, but I have a problem, my geometry after retime just go through the simulation, there is a small offset, I don't know why, any idea?
Hi! I got this to sim with the .0005 , but redshift would crash when I tried to render, so I re-simmed at .001 and made sure to change it to v2 on the file cache after the DOP I/O, but now the position of the bottle is slightly off and I didn't change any settings. I did change the re-time by 1 frame but since the control null is affecting both retimes, that shouldn't matter. Super weird!
hey I bought an orange off your csgtrader page today but RS doesn't render any texture on it? it never happened to me before so I am really clueless on this one
i did not understood the retime part. I wanted to do your idea whitout watching the video step on step, so I created the fluid sim in a geo node with a dopnet by myself, all this part is working, but i never did a retime before and its not really working. Did u just animate the retime parameter in your null? because i tried it but it dosent affect anything at all
My particles just disappear when I hit play, even without initial velocity. Any ideas? Thank you for the video! Edit:... it helps to make sure the simulation box actually includes the emitter.....
Hi, you can create a Null objects in the obj context and use the edit parameters interface to add a float slider. Simply right-klick it and copy parameter and go to you retime sop and paste relative references into the frame retime slider. Now you can control the retime from outside your sop network
Wonderful tut thank you! Is id really necessary in parts retime node ? Isn't Hou using point number without it ? I have tried to remove it and it seems to work properly without it...thanks!!
probably reducing the substepts right? every substep is a new calculation (i think) and the substeps ini the sim are put to 8 for the retime. @@joshmethven4710
It would have been nice if you explained more about the CACHE step for those who are not so knowledgeable... Can't get CACHE to run even though it saved it
YES! The cache step was super important since you can cache from the dopnet. Or the output in the solver. Or make a filecache node which I don't know where to do any of the cache since NONE of the attempts I have made will cache the substeps like is shown in the video.
@@FabianStrube hey! yeah sorry, I figured it out. I just had to point he UV group to the FBX data and it worked. Thank yo so much for replying. I do have another quesiton though, your PC is running this sooo smothly, what spec do you have? I have a i9 13900ks and 4090 and in struggles, it actually can't even cache 0.0005 like you did. What are you runningg and have you optimised something somwehre? Thank you so much!
Half of my fluid ball keeps going through my geometry even though I’m using 8 substeps on the retime node and the flip solver. I decreased the particle separation and decreased the division size on the object. How can I fix this?
@@FabianStrube Thank you for a great tutorial. Sorry for all the questions if you got the time. Using the trail sop after the retime will set all my v to 0 in the splash any idea what I'm doing wrong? - I tried just skipping the trail node and go directly into the att transfer which works but gives me crazy v values but maybe they just are a bit crazy the way I'm smashing my objects together?
@@JonasJCom Hi, no problem, glad you figured it out. I had some trouble with the velocity after retiming it myself. The trail sop set to compute velocity helped to calculate it again. Usually you can set the retime to scale velocity but it didnt really work for me. Seemed like a weird bug, since it put all my velocity to 0

Really well done tutorial, and appreciate you covered all aspects of the project, including materials and lighting. Great job.
Thanks alot!

So great tutorial. I love slowmo guys videos of all their Phantom footage and this is super great for water vfx !
Thank you Fabian. I was struggling with UV changing. After watching your video, I realized that I should apply only P in the retime SOP. Thank you
I'm happy I have find your channel, It is amazing! Thanks for your work!
goodstuff.. thank you!
thx very simple and cool!
Incredibly helpful, thank you!
That was a beauty! thank you
absolutely gorgeous
Wonderfully simulated fluid, Good job.
arouses admiration✨💎
Very concise and informative, thanks a lot!
very beautiful effect..Keepup
amazing tutorial man love it
Thanks for this great tutorial...
Really appreciate.

Hi, can you check if the uv attribute went missing somewhere on the way?
@@FabianStrube thanks Fabi for such a quick response. will check in a minute but it’s strange as it’s ok textures in vray 👀
@@FabianStrube just found the "bug" - imported obj has attribute of "shop_materialpath" in it so it overrides the material set in file sop it seems
amaizing!!!

I did excatly same as you but with my model and two flip objects with merge pin to flip solver, and after retime i have very bad and strange glitches.
Hi can you explain how your node Null CONTROL get you a frame section at 14:07 ? I don’t have it…. If anyone can help me

How you Render the substeps pls
Amazing tutorial - anything to help the 6+ hour caching on the simulation or is this normal?
I have the same problem with 32 RAM :( curious to have a reply.
@@damiencesure2848 I’ve figured out this is normal unfortunately 😬

Unfortunatly not
Hi! Loved your tutorial! Can I ask you how to export this animation in abc for C4D ? Thanks you!
Thank you! Just add an alembic rop after you meshed the Fluid and Export it 😊👍
I cant seem to get the textures right at all, the UV's don't line up - any idea how to get them to line up? thank you!

Did you check "use deforming geometry" on the static collision Object?
@@FabianStrube Yes, I did. It’s definitely animated in the Flip Sim. Could scene scale be a factor?
@@kextnext yes, it might be. Do you work in Real scale?
@@FabianStrube I fixed it! The deforming object shelf tool applied itself to the retime node instead of the animation. Thanks for your help!
How did. you calculate the initial v for the flipfluid to make it hit the animation? - Trial and error or is there a good way to calculate it?
It was a trail and error. But with the particle position and a velocity you should be able to calculate a future position of a particle in time.
@@FabianStrube Thank you for a great tutorial. Sorry for all the questions if you got the time.

ahh got it working with a shorter shutter speed and using the v directly from the retime without the trail node

Substep is missing in my retime node. I check some video on youtube as well they don't have the substep option too. how can i get it?
Are you using houdini 19?
@@FabianStrube I’m using Houdini 18.5
@@FabianStrube I can find it in the Parameter interface but it’s locked
@@ssaadd13579 I just checked it. It seems like they added the parameter in H19 for the retime Node.
@@FabianStrube thanks a lot!
how do you get the frame slider inside the control null?
On each Node in Houdini you can "edit parameter interface". There you can add different types of extra controls to your nodes.
Which one did you took?
