how to make particles not following emmiter? - AAABBBCCC - 03-11-2022

hi 
i made a firetruck and i used obi fluid to create water, but when truck moves or rotate particles follow its movements .
what should i do to make particles not following emmiter?

Particles won't follow the emitter, they'll follow the solver. This is because the simulation takes place in the solver's local space, see:

Quote:Solvers always perform the simulation in local space. This means that translating, rotating or scaling the solver will rigidly transform the simulation as a whole.

The typical setup to simulate in world space instead is to have a single solver at the center of your scene, and then have multiple emitters under its hierarchy.

kind regards,
