Muddy Waters

"mud_replaceable_blocks"

Defines which blocks can be replaced with mud during both world generation and random-tick updates.

"world_gen_mud_radius_noise.min_radius" "world_gen_mud_radius_noise.max_radius"

Defines the radius used to determine how far replaceable blocks can be converted into mud.

A radius of 0 only checks for water directly above the block. A radius of 1 checks for water adjacent to the block, and so on.

Note: If the minimum radius is set to 0 and random-tick mud conversion is enabled, mud will to slowly appear adjacent to water over time.

Radius values must be integers from 0 to 7, inclusive.

"world_gen_radius_noise.noise_stretch"

Defines how stretched out the mud noise out.

Higher values produce gradual transitions, while lower values create more frequent variation.

Value must be greater than zero.

"sea_level_mud_biomes"

Determines which biomes will always generate mud at sea level. By default, this only includes vanilla swamp and mangrove biomes.

"random_tick_mud_conversion_chance"

Determines the chance that a mud-replaceable block will become mud when adjacent to water after being hit with a random tick update.

A value of 1.0 causes eligible blocks to convert to mud as often as possible.

A value of 0.0 disables random-tick mud conversion entirely.

Must be a value from 0.0 to 1.0, inclusive.
