Particle motion question...

Recommended Posts

I'm a newbie in Houdini and I'm working on creating fireworks. I have this question, it maybe simple but I've worked on try to solve this for an afternoon...

How could I make the firework trail to be thicker at the top? (Like this and this)

Right now my firework trail is looking something like the image below.

Is it something to do with the pscale?

And could anyone tell me how can I achieve this? Thank you very much.

You could increase the sub stepping / Oversampling to have your nodes cook more often and have a stronger influence of the variance of your particles.
