Moss Fix
Highly configurable (or will be) server-side mod that fixes moss by allowing spread under transparent blocks
About this Mod
Moss Fix (remastered)
This mod's main feature is enhancing moss growth when using bonemeal to spread it manually. It allows moss to spread under transparent blocks, and lets you bonemeal moss even when there's a block above it. Also, this project is designed to be configurable and compatible by default, working across mod loaders and versions.
In addition, this mod provides two extra builtin resource packs that allow moss to spread onto sand and gravel in one, and cobblestone in the other. These can be disabled from the datapack selection screen or with /datapack disable.
You can check version and loader support on this spreadsheet.
