I made 3 fluid simulation with particles and i used the option offset (in domain settings) to make them started at different time. But the particles start ever from frame 0, someone know a way to fix it?
I cannot understand what you are trying to achieve and what you expect.
Can you upload a .blend file or some screen shots?
The fluid offset is used to set the simulation after it has been baked so you can change the time the simulation starts.
If the value is positive, it is as if the simulation starts that many frames before the start of the playback
If the value is negative, it is as if the simulation starts that many frames after the start of the playback
Best of luck
