Pixel Art Poison Cloud

A swelling pixel-art poison cloud bubbles, pops and drips toxic slime while green motes drift around it, as a seamless loop. Use it for a poison spell, a toxic trap or a hazard zone in a pixel-art game.

Pixel Art Poison Cloud is a pixel art effect that loops seamlessly every 3 seconds, drawn on a 384 by 336 canvas at 3x pixels. It is built from 14 particle emitters. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Pixel Art Poison Cloud is pixel art, drawn at 3x pixels so it sits on the same grid as your sprites, and built from 14 particle emitters. Techniques worth a look: sub-emitters set off by other particles, collisions, particles stretched along their motion, keyframed parameters and post filters (bloom). 2 scene layers (ground and props) show in the studio for context and stay out of every export.

Every layer emits continuously and the 3 s loop closes seamlessly, so it can run for as long as you need. To change its colour, select "Toxic glow" in the studio and edit Colour A and Colour B. Size on the same layer sets how big its particles are. Pixel size in the Pixel art panel sets how chunky it looks.

Layers, in draw order

  1. Floor glow, Toxic glowparticles / additiveA single long-lived particle that stays for the whole loop.
  2. Gas wispsparticlesA steady stream of smoke puffs from a disc. They grow as they age. Colour: green.
  3. Cloud backparticlesA stream of rings from a disc, its rate keyframed over the loop. They sway from side to side and swell and then shrink away. Colour: grey.
  4. Cloud bodyparticlesA stream of rings from a disc, its rate keyframed over the loop. They sway from side to side and swell and then shrink away. Colours range between white and pale green.
  5. Cloud crownparticlesA stream of rings from a disc, its rate keyframed over the loop. They sway from side to side and swell and then shrink away. Colour: white.
  6. Gas veilparticlesA steady stream of smoke puffs along a line. They grow as they age. Colour: green.
  7. Bubblesparticles / additiveA steady stream of bubbles from a disc. They set off "Pop droplets" when they die, set off "Pop flash" when they die and grow as they age. Colours range between pale lime and lime.
  8. Pop dropletsparticles / additivePixels set off by "Bubbles". They fall under gravity and slow down with drag. Colours range between pale lime and lime.
  9. Pop flashparticles / additiveRings set off by "Bubbles". Colour: pale lime.
  10. DripsparticlesA steady stream of streaks along a line. They set off "Drip splash" on impact, set off "Splat ring" on impact, fall under gravity and vanish when they hit something. Colours range between lime and green.

3 more layers are in the studio.

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.
