If you build in areas like the Basalt Deltas, you may have noticed the annoying particle effects. This pack disables that visual effect, making it easier to see. It also disables the overworld rain effects but not the ground particles.
You can probably tell that this is the most annoying part of the basalt deltas.
This is the Same world and screenshot spot, but there is no ash effects.
The basalt deltas isn't the only biome with this type of effects, it involves the warped forest, crimson forest, and the soul sand valley (in small amounts). The nether wastes doesn't have any of the visual effects.
I used the crimson forest as another example

Changed the name of the pack, since some people don't mention this as "weather particles"
