Light Dust
Light Dust adds floating dust particles to the world, spawned around light sources and tuned through the game config menu.
What it does
Light sources such as torches, lanterns and glowstone produce a configurable amount of dust that drifts in the air around them. The particles follow a physics model, so their motion shifts with the light level, the weather and the biome a player is passing through. Particles that move too far from the player are removed immediately, and a height limit can stop dust from spawning above a chosen coordinate.
The mod is built to stay lightweight on the client, which is the only side that runs it. Its options are gathered in the game config menu, where spawn mode can be set to fancy or fast, the per-tick sample count and block density can be lowered for better frame rates, and the ambient radius and opacity can be adjusted. Light Dust requires the Config Menu mod and works with it. Shaders often change how transparency renders, so players who find the dust too faint can raise the ambient dust opacity setting, with 0.45 as a suggested starting value. Light Dust is open source under the GNU Lesser General Public License v3.0 only.
Key features
Configurable light dust
Each light source produces a set amount of floating dust, and that amount can be changed in the config.
Dust physics
Particles move in response to light, weather and the biome around the player, not as fixed decoration.
Spawn and height controls
Options choose between fancy and fast spawning, limit the height where dust stops, and set the radius it appears in.
Density and distance caps
A hard maximum distance removes particles instantly, and a per-block cap sets how dense dust may get.

Use cases
Cave and night scenes
Dust around torches and lanterns adds visible atmosphere to underground areas and dim builds.
Performance tuning
Lowering the sample count and spawn radius reduces the work done on each frame for slower systems.
Who it’s for: Players who want visible light-source atmosphere in survival or building worlds, and players who set their own limits on particle density and performance.
