Emit all GPUParticles3D's particles at the same time

Godot Version

4.2.2.stable

Question

For a small first project I’m trying to make I need all the particles to appear at the same time.
I’ve tried playing around with One Shot and a couple other properties but couldn’t achieve the result.
I suspect it’s not a good idea to create a bunch of GPUParticles3D nodes that emit one particle each, so is there a better way?

Setting Explosiveness to 1 should achieve this.

Sorry guys. Nothing helps you find the answer by yourself as mush as asking for help.

This!

Just posted the question and I found it myself.
