Particle Culling/Disappearing

Hey everyone,



I’m using particle emitters and manually setting the position of each particle every frame.



However, sometimes squares of the particles won’t show up, as if they have been culled out or ignored. Like a square has been cut out of the particle emitter.



Does anyone know why this might be?



I’ll attach a screen shot later tonight

Ah sorry for the trouble, I just noticed I wasn’t using enough particles in my emitter
