Updraft

Updraft: long wind streaks rush up from a floor vent in a swaying column of air, lifting leaves, dust and motes that tumble out at the top. For platformer lifts and fans. Loops perfectly.

Updraft is an HD effect that loops seamlessly every 2 seconds, drawn on a 384 by 384 canvas. It is built from 5 particle emitters. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Updraft is a compact effect made from 5 particle emitters. One technique stands out: particles stretched along their motion. 3 scene layers (ground and props) show in the studio for context and stay out of every export.

Every layer emits continuously and the 2 s loop closes seamlessly, so it can run for as long as you need. To change its colour, select "Air Column" 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. Air Columnparticles / additiveA steady stream of soft glows across a box. Colours range between blue and pale blue.
  2. Rising Streaksparticles / additiveA steady stream of streaks across a box. They sway from side to side. Colours range between white and pale blue.
  3. Lifted LeavesparticlesA steady stream of leaves and petals along a line. They fall under gravity, sway from side to side and spin. Colours range between lime and gold.
  4. Lifted DustparticlesA steady stream of debris along a line. They sway from side to side. Colours range between gold and grey.

USING IT IN YOUR GAME

Phaser, PixiJS
The PNG sheet is a plain grid of frames that both can slice. A TexturePacker JSON atlas comes with a plan, from the studio.
Unity
Import the PNG sheet as a Sprite with Mode set to Multiple and slice it, or open the effect in the studio for a ready-made grid.
Godot 4, GameMaker, Aseprite
Open it in the studio and pick your engine in Export: with a plan, it writes the files that engine imports.
Web and chat
The GIF plays anywhere; the APNG keeps soft edges on any background.
Blend mode
This effect is made of light. For the same glow in your game, draw the sprite with additive blending, or export it on black from the studio for additive shaders.

Step by step: Unity, Godot 4, Roblox, GameMaker, Phaser and PixiJS, Aseprite, Web games (live runtime). Drawn with additive blending: see glow effects without a black box.
