In this tutorial video for Unreal and Unity, we add an Emitter Dimension parameter to our particle system. It allows us to define the size and shape of the volume that the particles spawn in. We also create ParticleStartSize and ParticleEndSize parameters so our particles can grow or shrink over time.

Here's last week's tutorial that shows how to generate the random values for our particles:
