three.js transparent maps issue

Question

I\'m creating loads of particles (80.000 to be exact) and I have set a transparent map, though, not all particles are transparent.

I\'m using a transparent PNG image

Answer 1

Those particles with black corners are rendered before anything behind them. So GL doesn't know yet there is something behind to blend. In order to make it look right you have to render these particles in the order of their z coordinates from back to front.
