Jeremy,
How's it going? Took a look at your blast. I like your ignition, very nice. Also like the way the smoke hugs the floor for a second before it rises. By the looks of it, temperature and feul are both dynamic. Have you keyed your incandescence imput bias parameters? Correct me if I'm wrong. You might want to shave a bit more frames of your imput bias, or key your feul and heat emission on your emitter. But your texturing is well done. How high a res container are you using?

Cheers

Gidday Wayne,

Im good thanks Thanks for the thumbs up! The resolution of the container is 100 all sides with incand and color textured, I believe I keyed the incand texture bias to 1 as it got older. There is a little bit of incand input bias keying going on but I actually relied on keying a tonne of Heat Released on the fuel grid instead of the input bias to get it really hot. I wanted a really long burning explosion hence the reason for the 3 second fire ball but I think it could actually be retimed as a faster explosion say 2.5 seconds. Yes both temp and fuel grid are dynamic.

OMG u blew up the busy lane..lol
love the timing...any more info abt ur rendering time?? any texturing used like color or incandenscence?
is it with real lights or default lighting..or m I seeing a HW render?
good start..now i have company for Ka-boom!
wil post my stuff tonight as i reach home.:-)
thnxs all

You guys sure are "Ka-boom freaks".

I like it Aikiman - nice to see something a bit different and it works well that the burning hangs on for a while.

Good work!


My main criticism is I don't think the lady on the left's reaction to the explosion is that realistic

I know I wanted a suicide bomber and all I got was some crazy Italian on a Vespa! Yep color and incand texturing using real lights - 3 spot setup - rendering I think was around 2 mins a frame.

Heres a playblast of more of the fluid, major cropping going on but you get the picture.

or check youtube if it is still processing in vimeo..btw youtube spoils the quality of my playblast ...!

I wonder if anyone here has watched "Knowing" yet? At the end of the movie, everything was destroyed by the radiation wave from the sun. It's so cool but it seems there is no behind the scene just yet. It would be nice if you guys change the way of explosion at one place to a trail explosion

Not sure what you mean, haven't seen it but would give it a go. Probably comes down to hardware if it is massive and my machine would crap itself, may not even be fluids, but like i say, haven't seen it.

I was stunned by the last fx sequence... I don't know if the last sequences were Maya fluids, although they certainly look like they could be from this thread. I do know the plane crash and explosions were Maya fluids - as per Phil's comments from modernmayhem.

In any case, you should check out this movie, as it is the poster child for this thread.

Hey guys,

I found the plane crash scene on Youtube. It's not in good quality but it's awesome. Skip the first 2 minutes if you want to see the plane crash right away.

The last scene in Knowing is not on Youtube yet but this trailer at second 55,56 and 57 is enough for you to know what I meant in the last post.

Yeah thats achievable though you'd be looking at a container at least 150 x 200 x 300 and my dual processor wouldnt have it in 'er to spit something out this week. My first thoughts would be to use an animted ramp as emission, everything else is plain old fuel, temp and velocity.

If I get some time I will try it in a small section / slice rather than a full shot. Unless somebody else wants to take this one up?

A peaceful boom without noise pollution.
this shuld be probably my last test with medium or low resolution..!
for a good billowing blast one needs a good or high resolution fluid (texturing optional). Low res things are good for distance shots not for the close up atleast!
this is a render of the playbalst :

& the render is drying at :
http://www.vimeo.com/4400488
or

I sometime feel tht playblast often looks more volumetric than renders.
but this was a test for "stooch" on texturing fluid with medium res fluid container.

I can give a shot in my free time or on a upcoming weekend or maybe "aiki" can we try together a portion of the blast? & then compiled together..In this way we might learn sumthing from each other. wt say?

Regards

How do you think the shot should be divided?
