Particles Emitter Help

[Geco]

i’m trying to use the Slave Parent and Child Emitter’s Master options in 2.4b without success.
can someone please help me with a detailed description on how it works and/or a scene example?

Geco,

Have you checked out this thread;

Little Particle Thread | Taron333 | CGSociety Forums

Not sure if it got an answer for you but I’ve just managed to get particles to follow through a tube successfully (with the help of isobar on irc) with collisions etc. Anyway that thread should be a starting point.

thanks rush123,
i’ve already read that thread, i’m waiting for Taron’s tutorials and demo scenes too.
please could you post a simple scene?

Geco,

I’ve put together a very quick example of “Slave particles” using 11 cubes. Hope it helps

thanks a lot rush123,
although what i’m trying to do is that kind of turbulences Taron did with the smoke in the vortex examples

Kinda nice, huh? Hihihi, no it’s done with the vortex force! You can have unlimited amounts of vortex centeres by picking a parent object as the “master” and check on “use children”. All the children will be now vortex controllers and their banking controls the amount of spin they get, y scale controls the twisting speed and the z scale controls the pull (magnet type) strength. This way you can animate the vortecees then to act like “airflow” dynamics. It’s kinda nice. I just dynamically parented one of the nulls to the ball as it moved through the steam.

i can’t understand how to do it. :sad:
do you know how it works?
please say yes

I should have asked what you wanted to achieve in the first place before replying, sorry for posting the wrong file.

Anyway, that’s funny because I asked the question that Taron replied to; I have since completed a few (abstract) tests and managed to constrain particle volume to the diameter a sphere by means of collisions, particle collision only work with the normals facing the right way (what does that mean I hear you shout! If collisions aren’t work reverse the normals), I used a sphere for the particles collisions detection and a particle stream inside the sphere. Ensure that your ‘collision radius’ is set correctly, and a tip that ‘play frames’ was set to see more actually the simulation, (tip & lots of help given from Isobar and others on irc). For the Sphere I used the ‘Grid & Wire’ node with some noise, because I was having some difficulties with glass surface and odd reflection. Anyway the only thing I haven’t got working yet was ‘vortex’,

Hope the info helps.

edit. just thought I’d show some particle fun stuff here as well

thanks rush123,
nice images!
btw i’ve found the vortex block :bounce:
it’s under the tool sub-tab in the setup tab

here is a first test:
