Particle System for Nuke 6 0.1.1 for Nuke (nuke script)

Awesome particle system - been looking for this for a long time for nuke... Question about the 'stars' picture you've put up... how do you acheive this? I've tried adding gold cards with glow and all sorts, but I can't seem to get away from the hard edged spheres?! Thanks for your help in advance
