View Full Version : effect???
04-01-2003, 07:48 PM
I have a dilemma. I want to make a flame for a airplane.Can someone tell me what is the best way/pipeline to achieve this effect. Do I use particles for this, our something else? Is there on net some kind a tutorial for this?

use a mix of particles and surfaces with animated fractals..
btw: exhaust flame or burning airplane?
exhaust would be best with surfaces only and some post glows

Could you please tell me little bit more info on how to make the effect. I would be indebted.
thaks in front

exhaust or fire?
04-02-2003, 11:21 AM
exhaust would be cool,
the fire I quess I will work out...

well if u want exhaust as well than put a few more particle emitters but with different shader.
04-04-2003, 09:28 AM
what do you thinmk isa the best type of emmiter for thius type of effect?

i would do an exhaust with objects only..
use a nurbs cylinder to start from and give it the shape of the exhaust.. now put on some 2d fractal texture that is streched in the direction of the flames.. animate that one by shifting the text placement in the exhaust direction and by animating the fractal itself.
duplicate that object some time, rotate over the exhaust direction axis and scale them differently..
now add a glow in maya or post..

alexx's method is definitely the best way. It also looks nice if you add a very low opacity rounded-cone shape in the middle with an orangey colour. Looks just like F14's taking off.
Thinking about it, you must be able to find some good shots for reference with the war on and everything. God, is that morbid?

I don't understand this part very well.Is this import?
Can you make a screenshot of it to be more clear, only if isn't a big thing...
Thanks in front for your time

jesus.. 10k as an attachment maximum size..
they can forbid attachments anyway since that is no size at all..
the jpg header is nearly as big.. :(
04-07-2003, 05:57 PM
I am going now to build it than I will send you a screenshot
04-07-2003, 07:29 PM
what do you think alexx?
I think I did't do a good job with shader,
and also the end of exhaust...
I would like you to send you a little avi. of it so you could see it and to tell me your opinion, how can I deo that(I mean on e-mail address).

as playme mentioned: watch some reference.
your exhaust is way to opaque right now..
check out some footage from real jets..
the exhaust is very transparent.
also it would be nearly 100% transparent already in the middle of your object..
check reality and imitate :)
(sorry no mail to public)

thanks for the respond, the bad thing
is that I don't have any reference:(((
I made it again, what do you think this time, I think it's ok?
I am having problem with edge transparence, I don't know how to solve that...
Can you give me some time on how to make a good shader?
What is the best way to animate this(model, not the shader), blend shape?I did it with blend shape
but I didn't like it. Do you have some ideas?
04-08-2003, 07:01 PM
with some glow...
what do you think alexx?
04-08-2003, 08:25 PM
i like the first image. only give it a subtile glow.. the second one is already overdone.
concerning the animation: basically i would really just animate the texture itself as i wrote earlier.
(you "shift" the fractal through it and additionally animate the fractal with the "animated" check box in the fractal node (as a value enter =time)
if that is to slow or fast change the time value to something like:
too fast =time/x
too slow= time*x
where you experiment with the x value
concerning the edge transparency:
connect a ramp to the color gain of your fractal that runs the transparency. to that ramp, connect a sampler infos facing ratio to the V coordinate (VRamp presumed).
make the ramp with 2 colors, one black one white and see the result.. like that you can make the edges transparent that they are not that prominent..
have a try and ask for help whenever you stumble.. (but try first.. the best way to learn :)
cheers & good luck

THANKS A LOT!!!
I am going now to try it like you say....
have a nice day
04-09-2003, 11:06 AM
I have made many different exhaust:)))),
now everything is depend on scene and upon which I will experiment(I made a default shader for exhaust)....
thanks a lot for your help
I have one question witch is not for this issue...
How did you put the photo(cow and dolphin) be side your user name? I want to put my photo:))
have a nice day

you need a certain amount of posts i think before you can do that..
somewhere in your profile..
