Hey guys, I hope you're well.

Just wondered if you guys had any idea how to drive particle scale by the brightness or luminance of a particle, so the brighter ones are larger?

I've been messing around with Point Wrangle but my VEX skills aren't up to the challenge!

Any thoughts would be appreciated,

Jeb

you can use the vex function luminance:

Thank you so much mate!
