Plasma Engine Exhaust

Plasma engine exhaust effect for 2D games: a violet plasma jet threaded with a writhing cyan ion stream, the two colours twisting together in the wake. Seamless loop.

Plasma Engine Exhaust is an HD effect that loops seamlessly every 1.5 seconds, drawn on a 512 by 256 canvas. It is built from 1 simulated smoke and fire layer and 3 particle emitters. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Plasma Engine Exhaust is built around a fluid simulation of fire and smoke on a grid, with 3 particle emitters on top. Techniques worth a look: particles feeding the fluid, turbulence, particles stretched along their motion and post filters (bloom).

Every layer emits continuously and the 1.5 s loop closes seamlessly, so it can run for as long as you need. To change the flame colour, select "Plasma" and edit Fire colours; Smoke colour sets the smoke. The colour swatches by the downloads recolour every layer at once.

Layers, in draw order

  1. PlasmafluidSimulated fire and smoke from a cone-shaped jet. "Ion stream" feed it.
  2. Ion streamparticles / additiveA steady stream of soft glows. They feed smoke and heat into the fluid, sway from side to side, grow as they age and slow down with drag. Colours range between orange and gold.
  3. Ion sparksparticles / additiveA steady stream of streaks. They wander on turbulence. Colours range between white and pale cyan.
  4. Nozzle glowparticles / additiveA steady stream of soft glows. Colours range between pale violet and pale cyan.

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.
