Drifting Nebula Background

Drifting nebula background: glowing magenta, violet and teal gas turns slowly and overlaps into bright cores, wispy filaments catch the light, dark dust lanes cross the clouds and young stars shine with four-point spikes, while fine star dust drifts through. Tiles seamlessly and loops perfectly, for space menus, star maps and sci-fi loading screens.

Drifting Nebula Background is an HD effect that loops seamlessly every 8 seconds, drawn on a 512 by 512 canvas. It is built from 9 particle emitters. Most layers blend additively, so it glows on dark backgrounds.

HOW IT'S MADE

Drifting Nebula Background stacks 9 particle emitters, each with its own job. Techniques worth a look: turbulence and post filters (bloom).

Every layer emits continuously and the 8 s loop closes seamlessly, so it can run for as long as you need. To change its colour, select "Violet Gas" 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.
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.
