Dust is a Minecraft mod that adds the white ash particle from the Basalt Deltas biome to the underground to simulate dust!
I'm glad you asked! It's just a mod that adds the white ash particle from the Basalt Deltas biome to the underground to simulate dust! After all, the air wouldn't be 100% clear in a real mineshaft :p
Now to the nitty gritty: It works by checking if the player has the sky above them while being below sea level and then scales the amount of particles based on depth.
It has a config system that you can access using Mod Menu, most things you can change in-game, but to change the particle you'll need to open the config file manually :)
As a note, it doesn't activate in the Lush Caves biome, since it already has it's own particles :p
This was inspired by Dylanstime in the moonflower Discord server, thanks for the idea!

Cave Dust requires the Fabric API but everything else Cave Dust needs is included. HOWEVER, I recommend Mod Menu to be able to use the config screen :p

Also! New features:
Heat rises! Near heat and light sources the dust will subtly rise.
Try going into a cave and running around! The air will flow around you and drag the dust around!
Streamlined code, should be faster.
Particles are spawned in sphere now.
Better options!

When installing on a client with lots of particle mods, reset the config using the reset button to default to the new default particle, unavoidable :(

Updated to 1.19.2!
In this update, I changed a bunch of stuff! Shocking really. No but really, a whole ton of things were changed, including:
The way particles are spawned, the spawn "check" now performs the check on the particle position instead of the player, very neat!
Added velocity randomness slider. weeeeeeeeeeeeeeeeeeeeeeeeee
Added superflat spawning toggle, since superflat worlds are hard to assume things for, they might be broken, so I left a toggle so you folks can decide to spawn them for yourselves :)
Changed license to MPL-2.0
Added keybinds to reload the config and toggle particle spawning! Handy!
Changed particles so that it spawns 10 times the amount! Should be nicer to adjust now!
