Particles? - How would you make dust kickup from helecopter rotors for example

Hi,

I am fairly versed with scripting, particles and etc - but I am having a small problem.

I have a hovering vehicle (copter)

I would like to know how I go about a Particle script that looks like ground dust being pushed away from the vehicle overhead.

I was thinking use Z-Bounce with an particle burst angle pointing towards the ground, but that isn't working out.

A good reference for what I'm looking to do would be to see a Dominus during hover mode. (which most of us have)

Thanks in advance.

p.s. you don't need to gimmie the whole script, just advise me on the meat and potatoes on how to go about this. Thanks.

I would recommend using llGround to find the ground height, and then rezzing a prim on the ground that will emit the 'dust' particles. Communicate with this prim to tell it when to die and where the helicopter is.

I'd love to implement something like this too! I am working on a hover vehicle that this would really suit nicely...

I am guessing that a prim (phantom) extending below the vehicle a certain amount which when colliding with ground or other objects would produce the effect?

I'll play with the idea tonight and report my findings - unless someone is about to tell me I'm an idiot and wating my time - which would be welcomed! I don't have a lot of spare time!

cheers

Ahh yes. I know how im going to emit the particles. The issue I am having is with the particles. I can't seem to generate ones that look like this type off emission.

Do a sort PATTERN_ANGLE with a custom 'dust cloud' particle, going slowly outward and upwards, expanding in size and becoming more transparent.

Ok fine (breaking down)

Can someone write a short but sweet particle script that would do this?

LOL... thanks

Maybe when I get on SL later tonight. Send me an IM in-world so I'll be reminded of it when I login.
