Fumefx: guidance needed.

#1

Hi all,

I’m pretty new to FFX, but i have chosen it as a method to construct a special effect as part of my uni course. I have chosen to simulate a nuclear/atomic explosion, i know its cliche and done to death but i thought it would look good if put together well. I have seen multiple videos around the web showing examples of such devices detonating in FFX but have found little in the way of tutorials, i would like to show you some examples of the aforementioned effect i have been working on piecing it together by trial and error.

any help and comments as how to progress and simulate this to a more realistic standard are greatfully appreciated.

Nuke01 - This was the precursor to the nest 2 tests.
Nuke02 - This one had more shape to the cloud but concludes rapidly.
Nuke03 - This worked quite well but i cant stop the smoke dissepating at the end.
Nuke04 - This was my first attempt, i quite liked the large bulbous cloud.

Nukes are an effect that is done alot. But rarely done well (excluding FX studios of cause). In fact, the next FX wars topic is nuke!

Personally, I’m not sure I would go along the fume path for a nuke, I would look into using After Burn (but I’m not sure sure of what your limited, or not limited too).

In fume, it would need to move at a fraction of a speed of what you have. The bigger something is, the slower it moves. But it will he hard for you to ‘shape’ your fume into a nuke shape, unless you use a lot of tricks to emit fume at the right places, and push it in the right directions. Look into vorticity and lowering the dispersion rate for starters to try and keep the fume lingering.

Welcome to the fumeFX world and have fun learning!

Is it? Now you’re talkin :slight_smile: I might join.

On the topic - you need much lower timescale to do that thing dude. The nuke is reeaaally big, so it doesnt travel as fast. Balance that up with buoyancy mainly, and you’ll be on a good path.

Thanks for the reply guys,

but I’m not sure sure of what your limited, or not limited too

we have a CGI experiment lab with afterburn, fume, etc so theres no real limitation on software. i opted to use FFX as all the vids i have found around the net seem to be FFX based,
I was thinking seeing as i have started in FFX should i continue or would it be wise to switch to afterburn as you mentioned?

I was working on the project a little more and lowered the dissipation towards the end i’ll try slowing it down now too :).

Thank you for the help :slight_smile:
