How do I randomise the emit(brightness) value in the materials settings. I want to vary the brightness of particles within a certain range.
There’s no one click solution that I can see so would I need a script for this.

Set keyframes for the emit value, then in the Graph Editor add a Noise modifier to the Emit curve.
