POV: You jump in to comments to write "twu thaizend" how i pronounced it 19th second lol :D

[@botondkelemen9857]

i just saw the "burning out" interju on the 3D Wizards channel and realliside that i'm on the way to burn out and thinking about a little brake to do something else, but now i see this awsome work and thinking about working again. Your videos are a big inspiration for me. Thank you so much!

[@nickmedukha]

Its always a balance mate, and i cannot say its my strongest side either haha But glad my tuts inspire you. Thank you!

[@Stevierees79]

Awesome tutorial dude. Really easy to follow along. What a awesome effect. Look forward to more tutorials.

[@nickmedukha]

Thanks a lot!

mems and funny character in your tutorial are lit😂😂😂😂😂too funny. its more funny becoz they appear on right time on right sentence .. thank for make me laugh and learn.

Congrats man, you hit the algorithm

thanks, are you referring the KZbin algorithm or Houdini algorithm? :D

Hi Nick, great tutorial btw! I was just wondering, do you happen to know which tutorial you used on the CGWiki that helped you to understand how to do the curved particles? I would like to understand it in more detail but couldn't find it on the CGWiki page.

[@RMAFIRE]

You have done a wonderful job🙂✨

[@focusmaya251]

Great useful ,thanks,subscribed 👍

[@antoningabolde4345]

I'm already doing my render, thanks a lot !

[@nickmedukha]

Wow thats fast :D Glad it was easy to follow!

[@stevenvanderlinden2334]

Really love your video's! Learning a lot!

[@khalilboss2855]

Your tutorials are amazing and unique! Keep it up

[@nickmedukha]

Thanks a lot man!

[@DeadbatteryVT1300]

Great tutorial !!

[@_thomasrichter_]

Hi Nick, first of all Thank you for your tutorials. They are really great and informative. However I have a question regarding the pyrosolver at 5:35. Could you please share your settings for Shape, Look and Export? That would be really helpful and nice of you. Thank you and keep up the great work.

[@ojisan4220]

tried to replicate it in Hou 18.5.596 and it is kinda impossible, Pyro Solver a year ago was not as advanced as these days... aghh

[@prathameshwaghamare4172]

@@ojisan4220 mine actually work till colour setting. colour ramp got update in houdini 19 so i think ramp isnt work in 18.5

welcome :)

[@check99999999999]

Heiy Nick, great tut'. By the way, how would you create particle that interact depending from a pscale attribute ?

[@motiondeshahil]

Thank you 👌👌

[@nickmedukha]

Welcome :)

[@Bacosil]

Thanks 🤩🙌

[@nickmedukha]

You're welcome 😊

[@frigbychilwether]

Hi, quick question. Could you not have just got the lines by adding a trail sop after the popnet - then do the add after that using your pt_id ? I only ask because I saw that trick in a Rohan Dalvi tutorial. Not sure if will have exactly the same look but without trying it but seems like the same sort of thing.

[@mehyarzarathoustra3604]

Hi nick, thanks for this tutorial can you tel how to retime those curves ? the defaults settings can't works correctly thank you

[@barchuk422]

hi, i don't understand how the add in the sop solver make curves, can someone help?

[@uzbtv2927]

Awsome😍😍

[@nickmedukha]

Thank you!

[@DeadbatteryVT1300]

how did you put the hairs on the strings? in the RS material. I have done it in Cinema but dont know how it would be done in Houdini

[@nvav970]

Класс! А почему strands, а не hair?

[@devanshparekh2746]

Hey Nick! I am running into issues with the pyro set up of this. I have followed everything and even tried it in a new project file. After the initial velocity from the point vel node is used in the pyro sim I am getting a very standard push up and then plumes towards the mid-top. What did I do wrong? I have checked the video over and over and my settings are the same as yours.

[@nickmedukha]

Hey Devansh! Rough guess would be - Are you rasterizing v in the volumerasterize? It sounds like the velocity hasnt passed to the solver there

[@yanagiya_rei9925]

Perhaps Nick has turned off Buoyancy in the shape tab of pyro solver.

[@johnlikesdrawing]

In the pyro solver under shape play around with the gravity and gravity direction. I was scratching my head at the same thing. But i think that might solve it, but am a houdini noob so someone might have a better answer.

[@harryward6060]

Hey Nick, do you know where I can find the information to use fox farm for my personal projects using Houdini? there's documentation for everything but Houdini. Cheers

[@nickmedukha]

Hey man, as far as I know they don't have a guide at this moment. I ll record a how-to this weekend.

[@snhly9120]

any good way to bring these into c4d/octane for rendering? with attributes too?

[@nickmedukha]

Nope, thats why Im rendering it in Houdini. To bring attributes you will need to convert these to polygons, which will likely result in Octane crashing. I was a huge fan of transferring .abc to C4d/Octane, but for some setups it just does not work, or works extremely weird/slow

[@aaronversiontwo4995]

Can anyone help with adjusting the Time Scale on the simulation? When I make a slow motion simulation in the pyro sim then the popnet goes crazy and makes a huge mess. What would I need to do to make this slow motion?

[@nickmedukha]

In the end of the chain, add a timewarp node and set a speed. Don't forget to checkbox interpolation :)

[@aaronversiontwo4995]

@@nickmedukha I just tried this and I get a very jittery mess. I was certain it would be some setting in the popnet that i may have missed. Are you sure a timewarp node is the best way?

[@aaronversiontwo4995]

Okay so I found that adjusting the Time Scale in the Pyro Solver and then adjusting the Velocity Scale in the popadvectbyvolume node seems to work.

[@aaronversiontwo4995]

Wait, no it doesn't the wires still go pretty fast just the pyro simulation is slow. I love hate houdini. The Interpolate between input frames on the timewarp node is causing the jitter and I have no idea how to fix it.

[@tomroohan]

What you can do is turn off the sopsolver in the popnet and then add a retime node after the popnet. Then use trails sop. It gives you a similar look.

[@STUDIOSTEPS_motion]

IS this in 19 ? Im running 18.5 and the settings for some stuff is different

[@nickmedukha]

Yes, its the SOP pyro which was introduced in 19 as I know

[@STUDIOSTEPS_motion]

@@nickmedukha cool yeah I would be a bit more upfront with what versions of houdini you are using and if you know if its a new feature in the software etc. I cant see it in your screen record. Thanks so much for doing these.

[@harryward6060]

What version of houdini is this?

[@aaronversiontwo4995]

Judging by all the extra attributes in the solver this is v19... So if you are using 18.5 still you might need to modify a few things.

[@nickmedukha]

19

[@harryward6060]

@@nickmedukha Wow, only 12 minutes to render on the farm. I did the same settings rendering on my pc and 93 frames took 12 hrs, with my scatter set to 600 haha

[@WPSoul]

туториалы все лучше, Октан к стати и в гудини работает хорошо. Хотя для таких вот мошн дизов то Houdini Karma XPU уже вполне подходит

[@nickmedukha]

Спасибо! Октан тестил - согласен, но с редшифтом охват больше, всетаки он популярней для гудини. А вот карма - очень интересно, но елки палки туда нужно времени ввалить чтоб понять :D

[@WPSoul]

@@nickmedukha так это только если что-то замудренное. Для моушн диза там за день разобраться, В 19 версии они как-то упростили все эти LOP контексты и действительно если разобраться то удобнее все потому что можно в основном контексте делать симуляцию а уже в LOP контексте выставлять свет, боксы и прочую геометрию которая нужна только для рендера. На основном канале Houdini была месяц назад серия по Karma XPU - довольно понятно основные вещи объяснили. Сейчас там уже вроде появилась возможность рендерить частицы, light linking. Это вопрос времени когда все перейдут на карму

[@aaronversiontwo4995]

Another downside to this tutorial.. You can only get the render look in the video IF you have Redshift. Rendering in mantra gives you big thick pasta like polygons.

[@nickmedukha]

Just google "Rendering Lines in Mantra", first search result link, sidefx forum. This tutorial specifically says - Houdini & Redshift.
