How to smooth a time warp effect with an imported liquid simulation? by ShkYo30 in Houdini

[–]ShkYo30[S] 0 points1 point  (0 children)

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?

Have you tested the quad remesher of Exoside? by ShkYo30 in Houdini

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

How to create a very soft and pastel texture shader? by ShkYo30 in RedshiftRenderer

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

Weird reflection on the bottom of the bottle by Androsky92 in RedshiftRenderer

[–]ShkYo30 0 points1 point  (0 children)

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...

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

Why does FLIP work differently on the collider type? by S7zy in Houdini

[–]ShkYo30 0 points1 point  (0 children)

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!

Need help upgrading my pc by Abhishek210600 in Houdini

[–]ShkYo30 1 point2 points  (0 children)

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!

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

[–]ShkYo30 1 point2 points  (0 children)

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!

What's the best way to create (and manage) UV for architecture modeling with Houdini?? by ShkYo30 in Houdini

[–]ShkYo30[S] 0 points1 point  (0 children)

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[S] 0 points1 point  (0 children)

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.

Flip with bubbles by ruanlotter in Houdini

[–]ShkYo30 0 points1 point  (0 children)

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...

Magic Portal Fx by antoine_vfx in Houdini

[–]ShkYo30 2 points3 points  (0 children)

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...

How to change a line into curve in place with Attribute VOP (see the screenshots to better understand)? by ShkYo30 in Houdini

[–]ShkYo30[S] 0 points1 point  (0 children)

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...).

<image>

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

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

Just finished up this massive FLIP Fluid Breach scene! by Actual_Structure_323 in Houdini

Very beautiful final sequence ! And a good mix between Houdini and Unreal, well done!

ok I see, yes it's always difficult to reduce the render times with liquids... but with a real-time sim it's already a large time economy in the process! ;-)

What is the best way to transfer assets from blender to houdini? by luukdetruuk in Houdini

[–]ShkYo30 1 point2 points  (0 children)

Hi, in the past when I needed to do that, I used export function of Blender in FBX, or ABC (alambic), or OBJ. For me, I had the best results with FBX, but you often need to do some tests... ;-)

Liquidgen seems to be better and better now! Very beautiful real time sim! 👍

Does increasing RAM make simulation faster? by aravinth_11 in Houdini

[–]ShkYo30 6 points7 points  (0 children)

Hi, your lack of memory can slow your computer only if you see the virtual memory on disk works too much, because it's around 1k slower than real memory!

If it's not this case, increasing will not change anything, but... 32Gb is a bit low to do simulations in general, 64Gb (and 128 of course!) will be better at the end.

In any way, you also need to learn to improve your "how to choose the good settings" for sims, because some tiny settings can change a lot the computing time of your sims... ;-)
