HOW IT'S MADE

Spark Portal Ring is drawn with 5 glowing strokes, lines with a hot core and a soft glow traced along their shapes, plus 1 particle emitter. Techniques worth a look: particles stretched along their motion and post filters (bloom).

Every layer emits continuously and the 2 s loop closes seamlessly, so it can run for as long as you need. To recolour the line, select "Spark rim" and change Core and Glow; Start and End set how much of it is drawn.

Layers, in draw order

  1. Portal hazesprite / additiveA placed glow.
  2. Spark rimstroke / additiveA glowing line traced along a circle. It wobbles like unstable energy.
  3. Crackling filamentstroke / additiveA glowing line traced along a circle. It wobbles like unstable energy. It flickers like a failing neon tube.
  4. Inner turnstroke / additiveA glowing line traced along a circle. It is drawn as dashes.
  5. Racing arc, Racing arc 2stroke / additiveA glowing line traced along a circle. A lit stretch of it travels round the shape.
  6. Flying sparksparticles / additiveA steady stream of streaks from a ring. They fall under gravity and slow down with drag. Colour runs from white to orange over each life.

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.
