Isn't there one over at the Particle Lab?

Tanarian: not sure but I'll check!

Hold on, let me dig the one up that I use.

[ Particle Studio HD ] Particle Generator Hud

When I make particles, I usually start with this. It is VASTLY easier than trying to code, make a change, save, and see results. I still go in and mess with raw code from time to time, but this makes my life way easier.

NeoBokrug: this is perfect thank you!

Beezle Warburton has a CC one! (I was trying to find this)
