Particles and FX

-Container for my particle/FX questions-

  1. Swirling FX
    Is there a way to create a gravitational field that particles can swirl around or script a similar event? Essentially I’m attempting to create particles far and have them swirl upwards like an upside-down Tornado.

Take a look at this. It has some stuff on particles and it may help you figure out how to do it.

Thank you for the link. I took a look and it got me started in the general direction I need. I asked the video’s author for more input

Sadly I am no closer to solving this than I was before.

I saw a thread where someone suggested creating empty nodes and assigning 1 to control global gravity and others for local gravity. This idea might help attract the particles if I could figure out a way to make them spawn in a ring at a set difference, and figure out a way to apply/write the gravity script for the individual nodes.

I sent the author of the post an email requesting he point me in the right direction (unity command references or something), but I never received a response.

I think I figured out a better way to phrase my question. Is there a way to set a gravity field’s settings on a per particle basis?

Yes you can, but its not called gravity field- you just set the settings that you want in the neg Y or whatever you want to do-

So if I created a node and assigned gravity to it (as explained in the Mario Galaxy example elsewhere on the forums), I could tell it to influence particles within a certain distance, and based on the current vector and apply those forces only only the particles within that distance?

LOL-

Yeah why not-
