What would be the best way to about adding exhust

[Phil]

I'm still working on my harrier model

[ http://www.hash.com/forums/index.php?act=A...e=post&id=63179 ]

I wondering what would be a good way to make exhaust for the nozzles.

I'm playing with the streak emitters but it's not cooperating to much.

any one have any views i can try ?

Thanks

Do you feel like trying another program to accomplish this?

 

Take a look at wondertouch.com, and check out Particle Illusion. You may be amazed.

 

I use it constantly.

[Phil]

I'm familiar with Particle Illusion from using Imagine. I would rather use A:M. I know it's capable. From seeing what John has done with particles i know it's possible. Time will tell, Thanks

In one of the tutorials there is a section where dust is added. I believe it was dust coming from under the Knight's foot - I know I saw it somewhere. I wonder if you can manipulate that dust to give the illusion of smoke for your Harrier.

 

Great looking Harrier BTW.

can you post a sample of what you are trying for...

[Phil]

Here's a few shots of what i've been able to achive. Just haven't been able to get the smoke to just ome out of the nozzle only. It also seems to go in the opposite direction when the aircraft is hovering downward. Also is there a way to increse the amount of thrust say smoke using a pose slider ? any help would be great

 

thanks

[johnl3d]

you could control the smoke direction in the chor by controling gravity ...if i have time i'll try it and post and you should be able to control a lot of things with sprites with pose sliders

Just haven't been able to get the smoke to just ome out of the nozzle only. It also seems to go in the opposite direction when the aircraft is hovering downward.

If you want to avoid the particles falling upward as the plane descends, you have to make sure the velocity of the particles that make up the exhaust is greater than the downward velocity of the plane. (The units of particle velocity aren't labeled in the settings, but they're actually measured in cm/sec.) And if you're not using sprites, you should.

 

Also is there a way to increse the amount of thrust say smoke using a pose slider ?

You can use a pose slider to control the particle emission rate.

[Phil]

I'm not having much luck controling the smoke using a pose slider.

do you create it just like a regular pose in the model ?

tried it that but no change. I must be leaving something out

[Phil]

Here's my latest attempt. I'm quite happy with it it but i'm still unable to create a pose silder to manioulate the the settings of the sprite to give it more thrust when it's hovering downwards

ok for got the link

My Webpage

and here's the nozzle project file maybe some can tell me what i'm doing wrong

nozzle.prj

[johnl3d]

Phil materials not enbedded so hard to see what you did

i put a pose slider just to control output on simple model

see if that helps

poseslider.prj

[Phil]

sorry, here's the project with embedded turned off.

Thank's i look at the project when i get off work

Thanks

nozzle.prj

[Phil]

I'm trying this again, I thought i knew how to make a pose slider, but i guess i'm doing it wrong. It dosent control any thing. the project you dis worked fine. I'm just unable to recreate the afeffect to control the rate of emission.

I 'll select to embed all this time

embednozzle.prj

Check out what Javier Poot did a good while ago:

While it's not exactly what you're going for, it get's excellent results.

[Phil]

Yes that was a wonderful render->

John showed me a good way to achive this, but I'm just unable to create

a pose slider to control it. I can create a pose slider to move the model and move CP's but not sprite settings

[johnl3d]

Hey Phil...here is a hint..let me know if this helps

Its better if you figure this out than you can do this whenever you want

 

 

 

questions click on my name and email me

They did this on "True Lies" - the model with Arnie in it was suspended from a crane and they rotoscoped in a mesh where the downdraught would be. There was a basic Harrier model too, but that was used to mask out the areas of the downdraught that were "behind" the live shoot model, and was set not to render.

 

The downdraught used a transparent blobby emitter that had its index of refreaction set. When rendered with the rotoscope, the background was distorted where the downdraguht produced a heat haze.

 

Couldn't you do something similar for this project? A harrier wouldn't actually produce much smoke - it's the sign of a very rich fuel mix.

[Phil]

John,

a picture is worth 1000 words. Your picture verified that i was infact following your inital instructions. turns out by uninstall all 3 versions of AM and just reinstalling the latest lets me create the pose slider that contols the the sprite settings to my hearts content. Thanks for sharing the knowledge

[Phil]

Here's a quick test of my progress

Phil's Attempt @ Animation

 

any comments are welcome

[Dhar]

Looks pretty good.

 

If you're trying to achieve realistic behavior, the jet acts more like a model, it lacks 'weight'. This is evident in the abrupt manuvering when it swoops to land, however, as the landing gears touch down you succeeded in adding 'follow thru' which indicates 'weight' to the whole machine.

 

I did a similar project a few years ago using Infini-D (which is no more) where it had the cool ability to reflect smoke emiters upwards once it touched the ground. I wonder if A:M has a similar feature?

My faux pas, it was 3DSMax.
