Niagara Particle timeline manipulation

I am new to UE5. I am trying to make a falling leaves simulation in Niagara.
The problem is : When I press play : everytime the loop starts from the first. So I don’t get falling leaves immediately in the games, it start from above and slowly come towards me.

I want the leaves to be already spawned and fallen from the source plane when I press play. Please help!

Is the FX it should be used for a rendered sequence there is an option to add “warm up frames” so that the FXs start playing before the rendering actually happens.
Otherwise you could add a second emitter to your Niagara System, duplicating the original one so that the particles look the same, but changing the spawn rate to a burst. Then you can define a box area below the source plane using the initial location module
