The best way to create weather effects like rain or snow, or festive confetti backgrounds. Apply to one layer, duplicate it 50 times, and get a complex organic system instantly.
Ideal for creating magical particle systems, nativity scene skies, or highlighting key elements in a motion graphics composition with a stylized "ting" or flash.
Use this to create stylized, animated fire for 2D explainer videos, holiday candle illustrations, or fireplace animations where you need a lightweight, scalable vector element.
