In fact, I also mentioned a similar scheme.
His second point is easy to understand.
For example: I have a "Size" value (floating point) (the particles are not the same size). I can assign this value to the floating point channel of the "MAPPING" operator. To define the gradient color of the particles.
So the same, this "Size" value can also be defined in the "Magnitude" value of the "Speed" operator, so that large particles can have a faster speed, and small particles are very small.
You can also apply the "Size" value to the "Strength" value of the "Force" operator. Such large particles are subject to heavy gravity, and small particles are subject to less force.
You can also apply the "Size" value to the Z axis of the "Spread" operator. Such large particles have a higher position on the Z axis.
