More Particles, more frames, more sim time.... :)
1.4 millions of particles, improved simulation parameters.
450 frames, Simulation time 1h 45 minutes (update: just 25 minutes with the new optimized version)
The color is fixed on the particles once all of them are emitted, it's just particleIdx / numParticles
Next time I'll show how to export the particles and import them as nParticles so you can create a poly surface and render.
