How to make a Flamethrower in Houdini | PyroFX + Karma

In this tutorial, I'll show you the simplest way to simulate a #flamethrower in #Houdini !
I'll show you how to create a custom source with a particle system and then use the pyro solver to simulate a flamethrower.
I'll use #Karma in the Solaris to render the project and finally, we do a basic setup of compositing inside the #Nuke.
This tutorial is perfect for beginners artists who want to improve her/his PyroFX knowledge but also some parts might be useful for more advanced artists too!

Thank you, that was one of the best and most to the point demonstration on how to use solaris!

[bananaboy]

Awesome! Love seeing more Karma.

Also would be cool to see an updated reel of work you've done over the last few years! Curious to see which sequences of these big movies / shows you did.

[NimaGhorab]

Thanks a million. Amazing and glorious as always.

[marvvfx]

High quality content as usual, good job!

I haven't watched it yet, but thank you for providing this tutorial, for beginners. It's quite hard to find good material on what seems to me a complicated first (tho I know for certain this is what it seems to me and not what it is).

Sir amazing work can you make a similar project rendering tutorial for Karma XPU

[paul_colton]

Thank you! Have you used Axiom Solver and if so, would be cool to see how to convert setups like this into one that uses Axiom instead.

Hi, great stuff dude, question, if I may, at about 5:14, "slow down" node, attributes, you are typing a star, space, and v, what is that shape in between looks like a small, upper case A, also, is the "V" lower or upper case. Thank you in advance, CZ

Hi! First of all great tutorial! I do have a question, why do you use microsolvers to change the disturbance and turbulence of the sim instead of using the built in parameters? Is there any difference? Thank you!

[solo-moon]

the source max sound it be 50-1 because its form 0 to 49 right

[kapilthakur]

Hi thank you for the tutorial can you tell me how do you determine the scale of the scene? this flamethrower is few meters big which is way bigger than real-life flamethrower does it affect the pyro simulation and if so what is the best scale for pyro simulations?

[miko]

Is pyro more preferred than axiom solver?

[rockeyrahul]

Sir how to learn 3D animation plz make videos sir

[sungerbob]

all houdini right? no axiom or anything?

Took exactly 7:15 seconds for this tutorial to fly completely off the rails. This program is ridiculous.
