Bubbling Toxic Swamp Loop

Bubbling toxic swamp loop, seen from above: glossy poison bubbles swell, wobble and pop into spreading ripples and flung droplets, dark sludge and pale scum drift on the surface, and glowing green mist rolls across with drifting spores. Tiles seamlessly and loops perfectly, for top-down poison bogs, sewers, acid pools and witch swamps.

Bubbling Toxic Swamp Loop is an HD effect that loops seamlessly every 6 seconds, drawn on a 512 by 512 canvas. It is built from 12 particle emitters.

HOW IT'S MADE

Bubbling Toxic Swamp Loop stacks 12 particle emitters, each with its own job. Techniques worth a look: sub-emitters set off by other particles, turbulence and post filters (bloom).

Every layer emits continuously and the 6 s loop closes seamlessly, so it can run for as long as you need. To change its colour, select "Toxic Mist" 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.

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.

Step by step: Unity, Godot 4, Roblox, GameMaker, Phaser and PixiJS, Aseprite, Web games (live runtime).
