Underwater Bubbles Loop

Underwater bubbles loop: bubbles of every size wobble up through drifting plankton, fine fizz and soft light. Tiles seamlessly and loops perfectly, for ocean levels, aquariums and underwater menus.

Underwater Bubbles Loop is an HD effect that loops seamlessly every 4 seconds, drawn on a 512 by 512 canvas. It is built from 6 particle emitters. Most layers blend additively, so it glows on dark backgrounds.

Free download with a transparent background, cropped to the effect, 120 frames at 30 fps. Use it in commercial games, no credit needed.

Licence: use it in any project, including paid commercial games such as a game sold on Steam. There is no per-project licence to buy and no credit needed. Terms.

Roblox: the download is a flipbook for a ParticleEmitter. Set FlipbookLayout to Grid8x8, FlipbookMode to OneShot and Lifetime to 4, then emit one particle per cycle. Roblox setup.

HOW IT'S MADE

Underwater Bubbles Loop stacks 6 particle emitters, each with its own job. Techniques worth a look: turbulence and post filters (bloom).

Every layer emits continuously and the 4 s loop closes seamlessly, so it can run for as long as you need. To change its colour, select "Light Blobs" in the studio and edit Colour A and Colour B. Size on the same layer sets how big its particles are.

Layers, in draw order

  1. Light Blobsparticles / additiveA steady stream of image sprites across a box. Colours range between cyan and blue.
  2. Planktonparticles / additiveA steady stream of dots across a box. They wander on turbulence. Colours range between cyan and pale cyan.
  3. Far Bubblesparticles / additiveA steady stream of bubbles across a box. They sway from side to side. Colours range between cyan and pale cyan.
  4. Fizz, Bubblesparticles / additiveA steady stream of bubbles across a box. They sway from side to side. Colours range between pale cyan and white.
  5. Near Bubblesparticles / additiveA steady stream of image sprites across a box. They sway from side to side. Colours range between pale cyan and white.

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.
