Initial state / offset particles

Hi everyone!

So, basicalally, I’m trying to make a rain sequence.

My render start at the 20th frame and I would like my particles to be already present in the frame.

The problem is that I can’t start simulation before frame 0 (for some reason, it is impossible to set the begining of a scene before frame 0).

So, my question is : how can I make an initial state OR offset my cache so my rain will be present from the begening.

Thanks in advance! :wink:
