TUTORIAL - REALISTIC FIRE - HOUDINI - REDSHIFT

[@o1os1s97]

The most comprehensible description I've heard and the result looks so cool. Thanks

[@resilientpicture]

You are welcome and thank you for your kind comments. 🙂

[@lordhackney]

Outstanding piece of work, thank you, and the hip files, updated, clearly arranged and annotated... So good I feel like a cheapskate only paying 15 dollars for it!

[@resilientpicture]

Thank you. That's very kind of you. You paid what I asked for, that's not cheapskate. 🙂 All the very best to you

[@user-sl309jd90]

You really know how to make a fire! Subscribed!

[@resilientpicture]

Thank you. Much appreciated. please checkout my latest houdini axiom fire series

[@delphinepinson8509]

Your tutorials are just amazing! Thank you so much for that!

[@resilientpicture]

Thank you again. I'm glad my tuts are helpful.

[@animator99_sculpt28]

Best fire Tut is here!!! thx you so much

[@resilientpicture]

Thank you and you are welcome. 🙂

[@Eventomaniac]

Thank you. This is a great tutorial.

[@resilientpicture]

You are welcome and thank you.

[@sanvfx]

Great Tutorial dude. Keep em comin!!

[@resilientpicture]

Thank you. Much appreciated

[@tomklejne3916]

Thanks for the tutorial, it's wonderful!

[@resilientpicture]

You are welcome. 🙂

[@limo5228]

Hello brother, your tutorial is very good, thank you very much for your selfless sharing. The small problem in the rendering part: the volume material fails in mat because the volume material needs to be created in the RS Material Builder.

[@resilientpicture]

Thank you, it's much appreciated. When I made this tutorial redshift volume rendering worked fine with this method, however, please checkout this explosion shader tutorial where I have explained the new method, I think redshift changed it a little bit. kzbin.info/www/bejne/mXPcfJiepLt4e6M As well, please checkout axiom realistic fire tutorial series here which is my latest houdini fire turorial kzbin.info/aero/PLi9R7ToKlBz18N6L39FgqvinktS5nPHuV

[@SwitchMaxFX]

would it be possible to export this out to cinema 4d?

[@resilientpicture]

I would say yes, If you export it as vdb and if Cinema4D can import vdb, its all good.

[@hazemmo7179]

very good

[@resilientpicture]

Thank you

[@zig3932]

Hi can someone tell which setting i would use in order to alter the direction of which the flame is moving

[@resilientpicture]

There should be a wind option in the solver or you can change the velocity in the source. Please check this tutorial kzbin.info/www/bejne/bXLXkIapm7KNocU

[@hanmarsh2876]

great tutorial:)! do you know if i can export this to unreal engine?

[@resilientpicture]

Thank you. Unfortunately I don't know how to export to unreal. It's something I need to start learning 🙂

[@bondell1840]

i bought the gumroad files, do you still have the pyrosolver files instead of axiom?

[@resilientpicture]

Hi, sorry for the delayed reply. You'll find pyro solver files within REALISTIC_FIRE.zip folder/REALISTIC_FIRE_ORIGINAL_GR.hiplc. Hope this helps

[@GameDevAraz]

Nice

[@resilientpicture]

Thank you

[@homfly]

Great tutorial. How can I get the alpha? When I rendering in RS a fire (volume) I have the color (RGB) but the alpha is all in white. I wanna export the alpha for compositing in nuke.

[@resilientpicture]

Thank you. When you are using a background the alpha gets eaten up by it. If you are using no background and just a some light you can use the alpha replace check box for it but when using a background you need to render out alpha separately using a second rop node where you set your grid as phantom object. In the first rop you can set the fire to be phantom. Does that make sense?

[@homfly]

@@resilientpicture my background is a heighfield with trees, rocks (instances) and oceans, that is....more volumes. I would like to render the heightfield, ocean and fire in separate render and then compositing in nuke, but I need these 3 alphas.

[@resilientpicture]

Ok in that case may you can use cryptomatte. It's an outstanding way to extract parts of render. Give it a google search. This may what you need. Otherwise you'll have to use separate rop nodes to render them setting appropriate items to phantom. But double check if volume is compatible with cryptomatte.

[@homfly]

@@resilientpicture im not sure if the cryptomatte is available for rsvolume. Yesterday I tried this method but it didnt work. I have never used cryptomatte. I will try to find a tutorial redshift+houdini+cryptomatte. Thanks!

[@resilientpicture]

Oh ok. Then you can use crypto for everything except volume. Render a separate rop for just volume with no background or everything else as phantom

[@mirdulamurali4871]

Will this work in Houdini apprentice version ?

[@resilientpicture]

Yes it will, maybe not redshift.

[@JoshuaAucker]

hello! newb here. First off thank you for the tut. So nice! So I followed this pretty closely and My fire is blocky in the render and I am not exactly sure what to look at to try and diagnose. Any hints?

[@resilientpicture]

You are most welcome :) hmm, the blockiness is due to voxels and sometimes it is related to the scene scale and motionblur should blur them out during render. if you need further help, please send me the file to [e-mail] and I can have a look at it for you.

[@JoshuaAucker]

@@resilientpicture thank you so much! Ill check it out now

[@resilientpicture]

@@JoshuaAucker Sure thing and you are most welcome. :)

[@mqmadrid]

hehe nice thanks! I subscribe because your boy asked to me, just joking nice tuts thanks...

[@resilientpicture]

Lol! Thanks. Much appreciated

[@msstudioccgi]

what your version ?

[@resilientpicture]

I think this particular tutorial was done using Houdini 18.5

[@shaheryar2chill]

Thankyou! Can i render in Mantra? Please tell me !

[@resilientpicture]

You are welcome. You can render in Mantra, yes, but I haven't covered it in this tutorial or the project file.

[@shaheryar2chill]

@@resilientpicture Do i just have to select Mantra just instead if i dont have Redshift? Can you please explain that ?

[@resilientpicture]

Well, you can't just select mantra because you need to change materials, lights and render too itself. There are a ton of tutorials on this on youtube.

[@guristoski2625]

When people buy your product do you answer your e-mails?

[@resilientpicture]

yes i do. did i miss yours?

[@guristoski2625]

Yes I used your KZbin E-mail as i have no other e-mail for you.

[@resilientpicture]

Ok can you please email to [e-mail]. I didn't know youtube had an email. You could have used gumroad to contact me instead.

[@resilientpicture]

Hi Guri, I responded to your email. Hope it makes sense.

[@drinnerd8532]

Okay... so, I'm starting to realize that if you aren't someone who even has a single clue about houdini you aren't going to be able to figure out a SINGLE thing. You clearly intended for this to be an intermediate level tutorial, because I have ZERO idea as to load a "pyro_source" node... so I can't even get past the first step. This is like, the 3rd or 4th tutorial I have to leave to search for yet, another, simpler, beginner-oriented tut. Maybe I can come back to this tutorial sometime next year after I've been able to get some kind of a freakin' clue about how to use Houdini... sigh*

[@resilientpicture]

Sorry about that Drinner D, I understand your frustration. However, this is indeed a beginner tutorial because the techniques used in this tut aren't complex. I should have mentioned at the start that this tutorial expects viewers to already know how to use houdini. Here's a link I suggest you look at. @Ninebetween has this excellent absolute beginner series called Houdini Isn't scary. Check it out kzbin.info/www/bejne/iqTZaYh9pqmcmMU I hope this helps.

[@drinnerd8532]

@@resilientpicture Sorry for being so frustrated. It's not your fault. You're just trying to help people by sharing what you know, and I appreciate that a great deal. It's my own fault for not understanding Houdini. I apologize for being all salty in your comments section. I will take a look at what you posted. Thanks for your help.

[@resilientpicture]

No problem, it's ok. Don't need to apologize. All of us started the same way. 🙂

[@TroubleShotVFX]

6:40 Houdini in a nutshell...

[@resilientpicture]

Lol! Sometimes it can be difficult.

[@TroubleShotVFX]

@@resilientpicture I followed every single step the whole way thought and my results are constantly different than the ones you get. For instance.. Setting Ignition Temperature to 2 makes my fire completely disappear. If I set it to 1.5 then I get flames that look nothing like yours but at least I can see something. No way to know what or where things went wrong. But the answer is so easy. You just need a complete mastery of all known options to troubleshoot things on your own. Why didn't I think of that! It boggles my mind that it a program can be so intentionally unintuitive.

[@resilientpicture]

I understand, I'm sorry that you are having trouble with this tutorial. In my opinion, houdini is so connected to real world physics things can look different depending on what you missed. There's nothing wrong with that. It's this very thing that make you dig deeper and learn more. I hope that you get the results you are looking for pretty soon.
