Change particle sizes over time

[josemendez]

Hello!

Is it possible to scale the particles over lifetime?

Thanks!

Hi there,

No, at least not their physical size (i.e. fluid resolution). Particles must represent a fixed volume of fluid during their lifetime, changing their size would either increase or decrease the fluid volume which is very unphysical.

If you want to change the size of particles, you can use a regular Shuriken particle system and either use the particle ad vector component to make them follow the velocity field of Obi particles, or directly set their position to be that of the Obi particles.

cheers!
