Make a Realistic Flamethrower in Blender - Iridesium 

I swear Joel only makes new tutorials so he can show off his new intros haha

So I might not be only one who came across some minor difficulties. But I think I might have overcome some of these hurdles. As someone already point out, Iridesium used Blender 2.83, thats the reason some might encounter different results. I used Blender 2.9 Some Questions I had while working on it: Why cant I see the fire in the Render Viewmode with Cycles, when working on the color? - Make sure you have Transparent set to off (Render Properties -> Film -> Transparent) Why does it seem that the flame initself seem way too explosive (no current and the source initself starts to explode)? There multiple things you have to tweak: In your smoke doman(the thing holding the smoke): Tweak it for your liking - (Physics Properties -> Fluid -> Gas -> Fire) - Reaction Speed: I used something like 2.5 (the higher the more smaller flames) - Vorticity: 0.02 (this one of the values which makes the flames seem more like being shot) - (Physics Properties -> Fluid -> Gas ) - Vorticity: 0.02 (this one of the values which makes the flames seem more like being shot) In your emitter(the thing shooting the flames): - (Particle Properties -> Velocity -> Object Alinged -> Based on the direction you have either x/y/z, (the tutorial used x). Tweak the number to get a more violent flame (I used something like 75 ms) - (Physics Properties -> Inital Velocity(Enabled) -> Source: 100 You may need to adjust some other values, but these setting seemed to influence the flame properties the most.

PSA IF YOU'RE HAVING PROBLEMS WITH THE FIRE SHADERS LOOKING BLOCKY ON BLENDER 3.0/3.1 An alternative: Instead of adding a Blackbody node in the Shader Editor (as shown at 10:33), use a ColorRamp instead. Plug in this node the same way as shown with the Blackbody. Change the color of both swatches as follows: Left swatch: H: 0.016 S: 1.0 V: 0.172 Right swatch: H: 0.023 S: 0.994 V: 1.0 You can tweak these settings to whatever looks best in your render. Amazing tutorial, can't wait to see an updated version! :D Thank you!

You posted this right when I needed it - thank you Joel!

For anyone having the same problem as me, the flame is constantly big size and ended up filling the domain, all you have to do is reduce fuel on emitter physical properties like 0.1(this will reduce the initial size of the flame). Thanks iridesium for sharing!

Boy this is the most realistic fire I ever saw from Blender

You got the best intros. Hand down.

Finally! A tutorial where the fire doesn't look like a bunch of orange blobs!

Legendary. Just legendary. I am so impressed! Those are some hot and awesome flames! Nice work!

Thank you, the fire looks so realistic! I can even feel the warmth and smell the smoke.

Few tutorials have the combo of easy to follow *and* a great looking result. Loving this.

Hats off to the intro and the amount of effort put into this video! Thanks a lot.

this is the first fire+smoke tutorial, which works. Thank you! Well done!

Your art in the intros are a great touch, keep it up!

I must say that that intro was outstanding. Bravo!!!

Wow, this method produces some really fierce renders, Thank you!

Iridesium your tutorials are really really good

this is the best fire tutorial I found, thanks so much for this

For those who are struggling... This did not work for me on the latest blender version. However it worked for me on version 2.83. Tyvm for this tutorial 😁 however you could have made life alot easier for us if you told us the final right settings (and slowed down on this) before hitting baking data just the once heh

Great tutorial. Very realistic. It fits in with a project I'm working on. Thank you. Great flames in 2.8 tutorial. .

that's a Hollywood grade intro right there

This is nice. Wow. Blender guys are lucky to have this. Subbed.

Holly moly dude. Love it. Deff gonna use iz.

Absolutely amazing. Thanks!

Absolutely amazing

some settings that worked well for me in 2.92, tweaking LordHelixe's response (thank you) Otherwise as in video DOMAIN: Gas Vorticity: 0.05 Dissolve: 20 (slow is checked) Fire: reaction Speed 1.25, Vorticity .05 EMITTER: Particles: set Normal to 0 m/s as others have stated, Velocity: 20 (mine was negative Y so it's set to -20 m/s) Physics: Fuel: 2, Flow Source Size: .5 (as in vid), Initial Velocity Source: 50.0

It looks awsome, I recall my first attempt with 3D Studio and the demo with camp fire. 3D has come very far i may say

That was pretty cool!!! I'll have to give it a shot someday!

Short and sweet !! Subscribed👍

Awesome tutorial! Just what I needed now :D One thing though, for me using the attribute node with "flame" instead of "heat" made it so I can use Noise to add more details and don't need to add too much resolution to my domain.

Only for referencement, amazing tutorial. Thanks you so much

Great tutorial! thanks for sharing!

i think ur new epic intro has COVID-19 cus it's kinda sick

The new intro is dope

I really enjoyed this tutorial. Many thanks from a fellow Joe! Having one small issue with the flame stream though. After about frame 50 the fire fills the adaptive domain, basically creating a "Fire Loaf" lol.

PSA: If anyone is struggling to achieve the same results as Iridesium but is struggling there is a reason WHY!! This kind of simulation for some strange reason is only achievable in Blender 2.83!! I struggled for hours tearing my hair out following this exact tutorial in Blender 2.9 and the results were nothing like this, so I downloaded every version of blender and repeated the same tutorial all with the same results?! Then when I got to 2.83 (The same version he is using) it worked PERFECTLY!! Mantaflow must be slightly different in 2.83 as the simulations work differently and look so much better!! Hope this helped someone.

Awesome work though 👍👍 love the ease of the tutorials

Cool stuff man!

this is fantastic!

Epic Intro = Instant Like

Great tutorial. Thank you.

Good video really helpful

This is amazing...

Thank you so much!!!!!!!!! Finally I understand it!!!!!!❤❤❤

🔥 🔥 Wow this is awesome. Thank you! 🔥 🔥

epicly awsome

Badass intro

Really HelpFul :)

What an intro!!!!

Wow, Thank you !

Amazing and easy thank u for this

That was damn great

It took me 2 hours to understand, but I think I learned a lot from this video

My goodness…😢 all my prayers were…. all I wanted… all the researches i did, were for nothing, and suddenly, at the middle of the night RU-vid suggestions showed me the treasure🎉 omg, thank u for your video very much)

Isn't there a bigger like button so i can smash it? Great tutorial dude! keep it up

good job

To fix the blocky fire: do everything the same but change the color mix node from mix to multiply. Then connect an rgb curves node between the multiply node and the principled shader.

Really love the tutorial, but man do I wanna see how you make your intro animations!

thanks for theme bro

okay this is cool

Thanks for the great tutorial! I now have a flame that's going to take a week to render lol

Just WOW!

Very good thanks

Like what is your computer setup? You kidnap the nasa supercomputer?😂

Great stuff, but I'm trying to figure out how you make the particles go straight. The tutorial doesn't seem to explain the sudden change at 2:30? Edit: Figured it out, You have to change the "Normal" underneath the Velocity tab to 0m/s

Damn it looks like a dragon breathing flames!

real gold

Thanks a lot!!!

thanks, brother

Thank you👍👍

Thank u so much

Interesting blender theme, previously a maya user perhaps? Either way, thanks for the tutorial, I really needed it :)

Ooowh...great 😳😳😳

Good shader

goooooooood

this guy is my favorite lol.

nice new sub

Wow, I checked like 20 other flame simulations. Should have started with this one. Best. F***ing. Smoke

Mhmhm your keys are providing some killer beats.

I don't know why, but I've tried several of your tutos and none of them have ever worked for me, it's too raging when you see the result. I don't know why, but when I do exactly the same thing as you, I don't get the same result (in fact, that's how it is with all the mentaflow tutorials I've been able to follow: none of them ever worked: either I get too many particles when I make water or in the case of your videos, the textures are never the same and neither is the result of the fire). I'm getting seriously fed up with Blender : never a tutorial works, it's really painful. But it's undeniable, your tutos are still well done (even if I don't know why, the calculations of my computer never give the same result).

Reminded me of blender guru's tutorial

I lost my mind at precisely 10:02

thx !

Very good!!! Greetings from Russia!!!

Just wow

Dude really awesome tutorials man. I have a question how can I make or can you make a tutorial, of a paper starting burning with a little fire and smoke burning the whole paper. I’m subscribing to see more tutorials from you 👍🤩

for anyone who have problems in newer versions of blender try to set initial velocity to 60-80 and it will look like the simulation in the video

Nice

I should really start to learn blender

thanks

That intro is amazing! Can you record an Tutorial?

Awesome tutorial! Thanks so much! However, when I baked mine at the 6 min mark in the video, mine came out more like a flaming stream than the billowing burst you have in yours. Any suggestions on either what I might be doing wrong, or how to improve it to match yours? Thanks!

Great! Now I can make my skeleton breath fire!

Thank you sir, now i have to bake again after 40 minutes, cause right after finishing you taught me something new! 😂 This channel clearly needs more subscribers!

How many glitch-effects do you want in your intro? Iridesium: YES

Thank you for the great tutorial. This takes ages to render with cycles :(

Hola despues de mucho intentos alfin encontre el error que le sucedio a algunos en los comentarios ( incluyendome ) . Para los que les aparece error en el minuto 9:04 lo primero que tienen que hacer antes de agregar lo demas es poner la "densidad" en 0 antes de agregar el "color ramp" , asi ya no les aparcera los cubos y les quedara como en el video

you are sooooooo coooooolbroooooo

Who cares for some flames, I came here for the intro!

How to Fix if your smoke shows a flame: In Blender 3.0.1 at minute 9:41 it is NOT "heat"... Name it "flame" and then it works. I literally sat 2 hours here and I was trying to figure out why it does not work, now here is the fix x(
