Particle Countdown 3 2 1 GO

HOW IT'S MADE

Particle Countdown 3 2 1 GO stacks 8 particle emitters, each with its own job. Techniques worth a look: particles stretched along their motion and post filters (bloom).

It loops seamlessly every 4 s, and 8 of its layers fire in bursts, so it pulses instead of flowing evenly. Start times are staggered from 0 s to 3.38 s, so the layers arrive one after another. To change its colour, select "3 ring" in the studio and edit Colour A and Colour B. Size on the same layer sets how big its particles are. The colour swatches by the downloads recolour every layer at once.

Layers, in draw order

1. 3 ringparticles / additiveA single particle at 0.38 s. It grows as it ages. Colour: red.
2. Number 3particles / additiveOne burst of 860 streaks from a ring at the start. They fly in and form a shape, swell and then shrink away and slow down with drag. Colours range between pale red and red.
3. 2 ringparticles / additiveA single particle at 1.38 s. It grows as it ages. Colour: orange.
4. Number 2particles / additiveOne burst of 840 streaks from a ring at 1 s. They fly in and form a shape, swell and then shrink away and slow down with drag. Colours range between pale orange and orange.
5. 1 ringparticles / additiveA single particle at 2.38 s. It grows as it ages. Colour: gold.
6. Number 1particles / additiveOne burst of 520 streaks from a ring at 2 s. They fly in and form a shape, swell and then shrink away and slow down with drag. Colours range between pale gold and gold.
7. GO! ringparticles / additiveA single particle at 3.38 s. It grows as it ages. Colour: green.
8. Number GO!particles / additiveOne burst of 2600 streaks from a ring at 3 s. They fly in and form a shape, swell and then shrink away and slow down with drag. Colours range between white and green.
