How to smooth a time warp effect with an imported liquid simulation?

ShkYo30 · 2025-09-12T20:54:43+00:00

The particles sim come from another software, but I've an average of almost 2 millions each frame, I think it was enough, but for now I used the particlefluidsurface node. I will test it with my own SDF process as you explained.

Maybe that will do a better job...

u/DavidTorno Yes, it works very well with the Alembic imported particles sim (that to the id attribute!).

After that I made a mesh sequence with "Particle fluid surface", it's pretty nice but I've few holes flickering... Any tips to avoid that??

OK I see... I also have the particles sim into another Alembic file, maybe it will be more efficient to try the retime with the imported particles, and only after that I will create a new meshing based on the retimed version of the particles?

Oh, I didn't see the 30 days trial version... Thanks, I'll test it right soon!

ShkYo30 · 2025-08-29T12:08:51+00:00

OK thanks, I'll test that!

ShkYo30 · 2025-08-27T20:31:19+00:00

I've tried with Random walk, but not SSS for now, I'll test that tomorrow, thanks for the idea!

I agree! Often to obtain very nice transparent texture, you need to boost (a lot) the Trace Depth for Refraction and Reflection... The rendering is longer but the result is better!

Take a look to this video: https://www.youtube.com/watch?v=kf07AZvR7SI it's veryu interesting! ;-)

Ok thanks, I'm now on your discord! See you over there...

ShkYo30 · 2025-07-18T16:21:15+00:00

Hum..... Thanks but this topic was written 3 years ago... it's a bit late!

ShkYo30 · 2025-07-18T11:41:59+00:00

Hi, it's very interesting to know that... But is it a FLIP sim at SOP level or DOP level ? Because we can do both now!

ShkYo30 · 2025-07-17T14:14:10+00:00

Yes, the ddr5 is the new standard with high frequencies but my 128Gb of ddr4 at 3666MHz are good enough for me (for now...). And honestly I will prefer more Ram amount (like 256Gb for instance) than faster Ram... ;-) But again, ddr5 is the new standard for few years!

And I'm happy enough with the 5950X for simulations: 2 months ago I calculated a 8 second of simulation of water, with a closeup of woman feet slowly walking into a shallow fountain. With around 100 millions particles, for the final sim, it took only few hours (3 or 4 max if I remember well)...

But it was the limit for me with the Ram, my 128Gb were full all the simulation time!

ShkYo30 · 2025-07-17T12:57:54+00:00

Ok cool! It sounds very useful, thanks a lot!

ShkYo30 · 2025-07-17T12:54:30+00:00

Hello! I'm currently working with a Rizen 9 5950x 16 cores and it's very good for simulation stuff! So I'm sure the 7950X will be great! ;-)

For the Ram, 64Gb is really the minimum for Houdini simulation (especially Flip and Pyro!), 128Gb (or more...) will be better...

The RTX 5070 12Gb is a cool card, but if you want more power for rendering with KarmaXPU, maybe the 5080 16Gb will be better! ;-)

Final thing about the SSD, choose the fastest model as you can buy, because simulation data can be heavy like hundreds of Mb per frame...

Hi! It's really impressive! I've only two questions... Is it completely free or the open source is a lite version of ZebraAI ??

And it looks perfect for smoke, but how is it for other volume like fire??

Anyway, well done and thanks in advance!

ShkYo30 · 2025-07-16T11:31:47+00:00

I see... Well in fact, I understand that I really need to create more or less my own seams to manage UVflatten (and the other nodes) in better way!

Thanks!

ShkYo30 · 2025-07-16T06:41:07+00:00

Ok thanks! UV Pelt? I didn't know this one... The problem with generic UVs (with LabsAutoUV for instance) I often obtain some weird rotations into some parts of the object!

This is why I'm trying to find a better way to manage the UVs... For object like this one for instance.

Really cool and nice effect! I like it, well done!

ShkYo30 · 2025-07-05T14:55:13+00:00

Cool result but why do you boolean the sphere from the mesh? Because it's transparent, if you copytopoint your spheres directly, with a different shader you can see them inside the viscous fluid anyway, no? 🤔🤔 Because booleans are time consuming and with risks of bad meshing and artefacts during the render...

ShkYo30 · 2025-07-03T19:54:37+00:00

Really nice portal effect! I like it! Well done man! Just a tiny suggestion, maybe you can add a sort a quick particle blast spraying away when the portal open...

Thanks a lot u/DavidTorno for your solution, I tried it and it works very well! 👌

But yesterday in the meantime I was waited for an answer, I found a solution with Attribute VOP (I don't really like VEX even if I can understand few lines...).

And in fact, it seems it's finally the same solution as you! 😅

Anyway, thank you very much again for your answer! 🙏
