Pyro for Beginners: Smoke Emitters in Houdini

[@Zango7]

Thank you for explaining each node in-depth, it's hard to find guides like these.

[@bubblepins]

Thanks for the comment!

[@rexxthunder]

I've been learning Houdini from random sources on the web for 3 weeks now. This is by far the best I've found. Great work!

[@bubblepins]

Thanks so much!!

[@Freg094]

Best Houdini guides on KZbin :)

[@bubblepins]

Thanks!

[@DoUGotMusic]

In-depth Houdini tutorials like this are very hard to find. What is even more arduous to find are videos that can concisely describe what each step does without getting too convoluted or complicated. You explained the concepts extremely well. I went through all the steps with you through the video and tested the parameters. Great job with the video. I hope you continue making more. I feel like I'm actually learning through the process and am understanding the parameters and how they work instead of copying someone.

[@bubblepins]

Thank you so much for the wonderful comment!

[@dobis5692]

Wow! You take the time to explain and illustrate the underlying concepts, you walk through the parameters, and even visually highlight what you're focusing on. So efficient. Thank you!

[@bubblepins]

Thanks for the awesome comment!

[@yusrighouse]

Man, you are an absolute saint for making this. Your videos look hard af to edit, but for a learner, it is super duper effective! Thank you so much BubblePins, houdini is my dream program, but without your help, I doubt I would be able to understand it well enough to do much.

[@bubblepins]

Thanks for watching! I had the same problem when I started learning Houdini, so I wanted to make videos that would target the learning curve in Houdini!

[@NaoAdachiVFX]

This is the most well-elaborated tutorial ever! Thank you for making it easy for beginners to understand! I think I will come back to this video many times

[@bubblepins]

THat's awesome to hear! Thanks for watching!

[@marioCazares]

Best tutorial I've seen! You explain everything that's going on so well

[@bubblepins]

Thanks so much! You just made my day a lot happier!

[@i20010]

This is the best pyro tutorial Ive seen so far, thank you!!

[@bubblepins]

Thanks!

[@kevinj9492]

Excellent tutorial. I am new to Houdini and this explains the 'why' as well as the 'how'.

[@bubblepins]

Thanks!

[@san60329]

I'm a Houdini beginner, I like this series of tutorials, very easy to understand.

[@bubblepins]

Thanks! I hope you'll enjoy my other videos too!

[@roachdoggjr722]

This video is really well made. Thank you for making it. Liked and subscribed

[@bubblepins]

Thanks so much! That means a lot!

Hummm... when adding a mountain node to the node tree (at 1:03), Houdini automatically turns it into a noise attribute node and the "time" parameter isn't available. Instead I used the "Animate node" option with a pulsation of 1 (default) but I don't know why I cannot use a mountain node... I'm using Houdini 19

[@bubblepins]

I think SideFX might have updated this node and changed a few parameter around in the new H19. I think they completely replaced the old mountain node with an attribute noise node. My guess is that the old mountain node probably had attribute noise embedded inside the mountain node and in H19 they probably updated the attribute noise node a lot and it probably made it incompatible with the old mountain node. My total guess.

[@valovanonym]

@@bubblepins Thanks for the detailed answer. From what I've seen in other Houdini 19 tutorials, the attribute noise node is now used instead of the mountain node so your guess is probably correct.

[@bubblepins]

@@valovanonym Yeah, it may be for the better. Let's give this new attribute noise a chance, maybe it'll surprise us!

[@saast2005]

Thank you for explaining things so clearly and telling why some things are set up as they are, not just slapping down nodes left and right :)

[@bubblepins]

Thanks for the comment! I'm happy you like watching my explanations!

[@chriskriut]

Really love a video like you did... great tutorial , a very fundamental concept for beginners clearly and useful, that's what we want. Hope to see more and more turorial from bubble pins. Thanks so much!!

Have you finished recording the fourth part of this pyro series, Ms BP? I loved the way you explained in the first three! Thank you!

[@bubblepins]

I have not, I'm so sorry, I got this huge backlog of videos. The Pyro rendering video will take some time, because Houdini 19 came out with a new Pyro bake node that I need to get familiar with. Sorry for the wait!

[@scidar1479]

Somebody can help me? This new Houdini dont has got Mountain just Attribute Noise Mountain. I search everywhere but dont found "TIME" paramater on this attri noise mountain node.... Somebody know where this that ? What is that parameter ?

[@bubblepins]

I am sorry about that, it's because this video is a little dated and SideFX had released several updates after I released this video. In the new Mountain node, there's a section that you expand called "Animation", after you expand that you'll see a check box that you can toggle for "Animate Noise". After you enable this, it will automatically make the noise move when you play the timeline. Hope that helps!

Woul you please tell me how to use denoiser in mantra? Is it enough to enable denoiser tab (NVIDIA OptiX Denoiser) in the render view or should I select something else for final rendering?

[@bubblepins]

I'm not sure if there is a denoiser in mantra, sorry I'm not s huge user of mantra. I know some basics of mantra that's about it.

[@fordperfect440]

I love the way you explain :)

[@abdullaharshak.n7870]

My temperature and burn voxels looks like cube. When i use pyro solver it initiates fire from a cubic shape looks weirded. I have also increased all the resolution stuff. It’s not because of resolution. How to get rid of it

[@bubblepins]

I'm not sure but it does sound like there isn't even voxels in your volume, the voxels determines the resolution of the volume. The smaller the number for the particle separation, the higher the number of voxels, or smaller the number of the voxel size, the higher the resolution of the volume. Try lowering the voxel size or particle seapartion size in your pyro setup or volume setup. But be careful, making too many voxels slows down the scene significantly!

[@risnandarmultimedia5296]

subscribed. good work. i like your in depth explanation

[@bubblepins]

Thanks!

[@deepakwadhwana8888]

Very nicely explained. Thank you so much for tutorial, I will let you know any other doubts if you can clarify.

[@bubblepins]

lol That's good! I am always looking to improve. THanks for watching!

[@deepakwadhwana8888]

😅 Okay, I will let you know for sure.

[@maxwen856231]

thx for your video, but at pyro source part if I choose volume scatter then everything disappeared, I don't know why

[@bubblepins]

Try double checking the parameters on the issoffset, especially the mode, if it's set to minimum, chances you won't see anything from the scatter. "ray intersect" is the default setting and works for most cases. This is a total guess. Let me know if you have any more issues. Hope that helps!

[@maxwen856231]

@@bubblepins thank you very much

[@sharath2273]

How do you get the hovering parameters view on the node editor?

[@bubblepins]

The Parameters Panel on the right top corner of the Node Network? Mouse hover over the Parameters Panel and press "P" on the keyboard. Hope that helps!

[@sharath2273]

@@bubblepins Thanks! Great tutorials, keep up the great work!

[@kmbm23]

hey, i have 18.5 and theres a problem. on the pyro source node, i'm trying to change to source smoke but it keeps changing back to initialize. Any ideas? I cant change to any other option... it reverts to 'initialize'. Thanks. and Great tut btw...

[@bubblepins]

ohh I think I know what the problem is. That dropdown is only there to add the corresponding fields below that panel. It'll always flip back to Initialize. Once you pick something like Source Smoke, it'll add the related Volume fields. Sorry in the delay in replying back, I've been super busy getting ready for Live STreams this week and I was a little confused in what you were describing until it just clicked in my head. Hope that helps!

[@Eclair_Visual]

6:15 how ?

[@bubblepins]

sorry, I don't understand. Can you elaborate a little bit?

[@Eclair_Visual]

@@bubblepins How did you open the pannel "geometry" with pscale

[@bubblepins]

@@Eclair_Visual The Geometry Spreadsheet is a panel that was already opened from the beginning, but you can hide panels. You do have to open up a pane first, if you click on the + sign and then "New Pane Tab Type" → Inspectors → Geometry Spreadsheet, this will open it up in the pane. Then to hide it, hover the mouse over the middle of the pane on the top thin bar, there's a very faint arrow icon. Once the mouse is over it, you'll see the mouse icon turn into an arrow.

[@Eclair_Visual]

@@bubblepins thx 🙂

[@mrglowtm]

How did you set up your workspace like that?

[@bubblepins]

If you right click the icon on the top right of each panel, you'll get an option to tear it left/right/top/bottom then just switch the panel to the one you want. And save it as a workspace, do you don't have to do it the next time. Hope that helps!

[@mrglowtm]

@@bubblepins How did you put the parameters in the corner like that?

[@bubblepins]

@@mrglowtm When the mouse is hovering over the node network panel, press "P" on the keyboard, it'll open up the parameters panel in the right top corner. There's also a bunch of other similar shortcuts, like "C" for the colors to color the nodes, "B" to display a mini node network on the bottom left corner. Hope that helps!

[@mrglowtm]

@@bubblepins You are a savior thank you!

[@goldkerux]

Hi thanks for the amazing tuts! Just a quick question, how do you view the dopnet in the geo level?

[@bubblepins]

There's actually 2 different types of dopnets you can create. You can create one on the geo level called Autodopnet and the one located inside a geo level is called dopnet. Most of Houdini's Shelf Tools will create an Autodopnet. Hope that helps!

[@srikanthrathod5772]

Thank you for making detailed vedio

[@bubblepins]

I really like explaining things. I was super happy when I found out I could use it for stuff like this!

[@Terandium]

The "better" way of scattering points all across the volume of the sphere. Is by using the: points from volume node instead of: isooffset and scatter

[@bubblepins]

oh wow, I'm super late in responding to this comment. I'm so sorry I'm not sure why YT is so unreliable with the notifications. But you are right, you can use the points from volume node, that will do it! I guess I got into the habit of using isooffset & scatter.

[@tleanvasner6866]

this is a good quality tutorial but i think you spent a bit too much time accenting on the importance of finding a sweet spot for voxel size. it's like quarter of a video itself

[@eg_raul]

Yooo thanks to this comment I started adjusting my voxel size scale upwards instead of downwards in the volumerasterize node and finally got my volume to be visible, so thanks haha
