Stars

Ambient reference

FXMasterParticle effectAPI type: stars

Slow ambient star particles for astral scenes, dreamlike spaces, or void backgrounds.

Ambient effects add visible movement without replacing the full weather setup. Use them on their own or layer them with another particle or filter.

Package	FXMaster
Effect kind	Particle effect
Category	Ambient
Runtime type	stars
Exposed parameters	16

Important controls

• Orbit: Makes stars circulate around the effect area instead of only crossing the canvas in a straight or drifting path.
• Scale: Changes the rendered size of stars. It does not change how many particles are present.
• Speed: Changes how quickly stars move and animate across the canvas. It does not change particle size or count.
• Density: Changes how many stars are visible or spawned at once. It does not change their size.
• Opacity: Controls the transparency of stars. Lower values allow more of the map to show through.

Setup notes

• Lower Density works well when Stars are used as a subtle accent. Raise it when the stars should become a stronger background layer.
• Tint, Opacity, and Scale usually change the overall mood more than Density alone.

Direct-effect API example

The Direct Effect API creates a separate row shown through Manage API Effects. Add a stable apiMacro_…_p or apiMacro_…_f ID when later macro calls need to update or stop the same row.

const created = await FXMASTER.api.effects.play({
  particles: [{
    "id": "apiMacro_wikistars_p",
    "type": "stars",
    "options": {
      "belowTokens": false,
      "tint": {
        "value": "#bee8ee",
        "apply": false
      },
      "orbit": false,
      "scale": 0.27,
      "speed": 0.27
    }
  }],
});

await FXMASTER.api.effects.particles.stop(created.particles);
