FXWars! FLAMETHROWER! : Nahuel Letizia, Freeform Entry


Hi! This is my first FXWars challenge! I will be posting some wip soon.
I’ll be using FumeFx for the simulation.

The flamethrower I want to achieve will be similar to these videos:



Here is my first test I’m posting here.



awesome flames nahuel but i think the fume should be darker



Thanks for your comment Toufik!

In this update, i darkened the smoke:


Here is another update:

I added side-emitted flames to the flamethrower, just like in the reference, and changed the fire color a little bit.
I will be adding more details soon. :slight_smile:


This looks pretty good already I agree. The smoke lighting is probably way too high, you should definetly reduce it. I´d love to see a more horizontal spitting instead of these up and down movements (I never understood why people do that…well, probably there must be monster spiders at the ceiling :smiley: ) and you could still do some more fire color correction.

Otherwise, good work so far! Looking out for more.


Yeah, in the final shot I’ll make sure the flamethrower is horizontal :D. And as for the lighting…do you mean the smoke has to be darker?


no no, I mean the lighting that comes from the fire should have less influence on the smoke. The smoke lighting itself is fine I´d say.

In this video I added a flame burst when the emission stopped. You can see it at 0:23 of the reference video: http://www.youtube.com/watch?v=7dmE-emrrAs
I also reduced the fire lighting influence on the smoke .


Looks good. The bursting is indeed an important addition! However, forgive me if I need to bring it up again, but I still think the extent of the fire lighting is still too big. In your posted reference video, check out 0:12 when he starts spitting again. As you can see the influence of the fire lighting is very short. That´s because the fuel does not burn very hot. So I think this would really add to the realism (although one could of course argue that artistically it looks more stylish with a bigger influence width…but well, I am the physical guy here :smiley: ).

Anyway, getting better.


New update: http://vimeo.com/13460547 (it’s converting)

In this video I reduced the multiple scattering (fire lighting influence on the smoke).

In the next update, I’ll add the ignition flame :slight_smile:

Here is a before/after image:


In the image it looks already much better now! :slight_smile:


Thanks! :slight_smile: The video is online now.


yes, now you got it. looking much more convincing. :slight_smile:


Wow, it looks awesome!



Thanks guys! :slight_smile:

Here is a preview of the ignition flame. Unfortunately I couldn’t find any close-up reference of it. But this is what I came up with:



Looking already good! Not much to say about it. Maybe the flames are a little bit too crispy otherwise the speed and turbulence is good. Look at the mythbuster reference I posted: http://forums.cgsociety.org/showthread.php?f=139&t=897872

The ignition flame can be seen quite good there (I used it myself as reference for my ignition flame, see my thread).

Thanks for that reference Samir!
In this video I changed the fire colors.
In the next update, the flamethrower will be more horizontal and I’ll add the ignition flame!


New update: http://vimeo.com/13585837

In this video the flamethrower is more horizontal and it has the ignition flame.
This weekend I’ll try to shoot some footage. :slight_smile:


Wow man, really nice. Are you using FumeFx? if so can you explain a little your process?
are you using a particle source, or just a simple source with really high velocity? what is your grid size and spacing? if particles is it pflow/legacy, or thinking?

Really nice work man, I truly think right now you have the most realistic looking sim out of everyone.

My only worry is that the scale seems maybe a bit off? When you attach it to some footage it may look to small? I don’t know it looks like maybe its only shooting 10-15 feet when it should be more like 35-40 Maybe I’m wrong. But really nice sim none the less man. Good Luck.
