Legendary Chest Opening

A legendary chest opening: a gold sigil writes itself on the floor, the chest lands in it and rumbles, then bursts open with a gold light pillar, a rainbow ripple of rings, a coin and gem geyser and rainbow glitter. Plays once.

Legendary Chest Opening is an HD effect that loops seamlessly every 3.2 seconds, drawn on a 512 by 512 canvas. It is built from 8 particle emitters, 1 laser beam and 8 glowing strokes. Most layers blend additively, so it glows on dark backgrounds.

Free download with a transparent background, cropped to the effect, 96 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 3.2, then emit one particle per cycle. Roblox setup.

HOW IT'S MADE

Legendary Chest Opening is drawn with 8 glowing strokes, lines with a hot core and a soft glow traced along their shapes, plus 8 particle emitters. Techniques worth a look: laser beams, sprite modules, collisions, particles stretched along their motion and post filters (bloom and chromatic aberration).

It loops seamlessly every 3.2 s, and 6 of its layers fire in bursts, so it pulses instead of flowing evenly. Start times are staggered from 0 s to 1.46 s, so the layers arrive one after another. To recolour the line, select "Sigil Ring" and change Core and Glow; Start and End set how much of it is drawn.

Layers, in draw order

  1. Sigil Ringstroke / additiveA glowing line traced along a circle. Its start and end are keyframed, so it writes itself on and off.
  2. Sigil Starstroke / additiveA glowing line traced along a star. Its start and end are keyframed, so it writes itself on and off.
  3. Floor Glow, Inner Glow, Seam Leaksprite / additiveA placed glow.
  4. ShadowspriteA placed glow. Extras: keyframed motion.
  5. Landing DustparticlesOne burst of 10 smoke puffs from a ring at 0.22 s. They grow as they age, spin and slow down with drag. Colour: grey.
  6. Gold Pillarlaser / additiveA laser beam firing upward. It pulses 6 times a second.
  7. Light Raysparticles / additiveOne burst of 16 streaks at 1.4 s. They swell and then shrink away. Colours range between gold and orange.
  8. Lid Open, Chest, LidspriteA placed image. Extras: outline and keyframed motion.
  9. Seam Sparksparticles / additiveA stream of streaks along a line, its rate keyframed over the loop. They slow down with drag. Colour runs from white to gold over each life.
  10. Open Flashparticles / additiveA single particle at 1.4 s. It grows as it ages. Colour: white.

10 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.
