Epic Chest Opening

An epic chest opening: a purple-trimmed chest lifts off the floor as purple motes spiral in and lightning crackles round it, then slams open with a light pillar, rings, stars and a gem and coin fountain. Plays once.

Epic Chest Opening is an HD effect that loops seamlessly every 2.6 seconds, drawn on a 512 by 512 canvas. It is built from 9 particle emitters, 3 lightning bolts and 2 glowing strokes. Most layers blend additively, so it glows on dark backgrounds.

Free download with a transparent background, cropped to the effect, 78 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 2.6, then emit one particle per cycle. Roblox setup.

HOW IT'S MADE

Epic Chest Opening gets its crackle from 3 lightning bolts (a new jagged path on every strike), backed by 9 particle emitters. Techniques worth a look: glowing strokes traced along shapes, a vortex, magnets, sprite modules and post filters (bloom and chromatic aberration).

It loops seamlessly every 2.6 s, and 7 of its layers fire in bursts, so it pulses instead of flowing evenly. Start times are staggered from 0 s to 1.25 s, so the layers arrive one after another. To change its colour, select "Pillar Width" 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. ShadowspriteA placed glow. Extras: keyframed motion.
  2. Landing DustparticlesOne burst of 10 smoke puffs from a ring at 0.2 s. They grow as they age, spin and slow down with drag. Colour: grey.
  3. Light Pillarparticles / additiveA single particle at 1.2 s. Colour: white.
  4. Pillar Widthparticles / additiveA single particle at 1.2 s. Colour: violet.
  5. Spiral Motesparticles / additiveA stream of streaks from a ring, its rate keyframed over the loop. They spiral into a vortex, are swallowed by a magnet at its centre and slow down with drag. Colour runs from violet to white over each life.
  6. Lid Open, Chest, LidspriteA placed image. Extras: palette swap, outline and keyframed motion.
  7. Inner Glow, Seam Leaksprite / additiveA placed glow.
  8. Arc 1, Arc 2, Arc 3lightning / additiveA lightning bolt striking downward every 0.16 s. It forks into branches. Each strike lands somewhere new.
  9. Open Flashparticles / additiveA single particle at 1.2 s. It grows as it ages. Colour: white.
  10. Purple Ring, Floor Ringstroke / additiveA glowing line traced along a circle.

4 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.
