How accelerate particles by force field before frame 0?


Is there a way to start a force field acting far before frame 0 ?

Example: I’ve a wind force field that moves particles. The particles birth is starting already at frame -1.000. But they begin to accelerate at Frame 1 and getting faster after a period of frames.

Is it possible to have fast moving particles already at frame 1?
Or do I have to increase the animation length and set the rendering start frame later, let’s say at frame 500 to start with fast moving particles?

Thank you


What about using the velocity params in the Particule Emitter settings ? It permits to choose an initial velocity for your particules as soon as they are created


Thank you. I’ll check it.
