Particle System, External Forces for dynamic systems

Questions
1

Basically I want to apply forces to simulate e.g. Wind, turbulences and so on.

So it is a bit different than applying properties over lifetime. I want more “external” forces to influence the system. Gravity would be one idea. Can the gravity of a particle system be changed dynamically?

Or are there any field like modifiers, vortices, gravity fields aso?

Best.

To accomplish that you will need either a custom update:

or maybe a noise texture might be enough: Particle System Intro | Babylon.js Documentation

Oh cool. Missed that.
I will try the noise.

Custom update you mean by using the particles update function?

yup exactly so you can control it as you see fit.
