Ice Wall Rising

HOW IT'S MADE

Ice Wall Rising stacks 9 particle emitters, each with its own job. Techniques worth a look: collisions, keyframed parameters and post filters (bloom and vignette). 2 scene layers (ground and props) show in the studio for context and stay out of every export.

It loops seamlessly every 3 s, and 6 of its layers fire in bursts, so it pulses instead of flowing evenly. Start times are staggered from 0 s to 1.89 s, so the layers arrive one after another. To change its colour, select "Rising Mist" in the studio and edit Colour A and Colour B. Size on the same layer sets how big its particles are.

Layers, in draw order

1. Frost LineparticlesA single long-lived particle that stays for the whole loop. It grows as it ages.
2. Rising Mistparticles / additiveA stream of soft glows along a line, its rate keyframed over the loop. They grow as they age. Colours range between blue and pale blue.
3. Wall FormingparticlesOne burst of 44 shards at 0.05 s. They fly in and form a shape.
4. Wall BreakingparticlesOne burst of 44 shards at 1.89 s. They are flung outward, fall under gravity and bounce when they hit something.
5. Top Glintsparticles / additiveA stream of stars along a line, its rate keyframed over the loop. They swell and then shrink away. Colours range between white and pale cyan.
6. Lock Flashparticles / additiveA single particle at 0.58 s. Colour: pale cyan.
7. Break Flashparticles / additiveA single particle at 1.89 s. Colour: white.
8. Cold Puffparticles / additiveOne burst of 14 soft glows across a box at 1.89 s. They grow as they age and slow down with drag. Colours range between blue and pale blue.
9. Ice ChipsparticlesOne burst of 40 shards across a box at 1.89 s. They fall under gravity, bounce when they hit something and spin. Colours range between white and blue.
