how do i create a fast twinkling sparkles effect while having the particles not die fast. i want it to continue it's movement in the direction i choose, and it musn't disappear for the duration that i set. but i need a magical pixidust effect (fast twinkling). just an area emitter and let the particles move up or downwards.
Make sure that the alpha (transparency) gradient for the particle starts and ends black, and goes white in the middle, then slide the "repeat" slider to the right. If you slide it all the way right (which I believe the value is "10") and that's still not enough "sparkle", then add points to the gradient so it goes black / white / black / white etc.
