Very Moist

Farmland in Minecraft uses 8 levels of moisture, yet only 2 of them have unique textures, this resource pack adds in the extra 6 levels of moisture that currently have no unique texture.

Farmland only uses the extra levels of moisture when drying up, so rain and water will still convert farmland into hydrated farmland instantly.

Ignore the warning "made for a newer version of Minecraft", it works from the latest snapshot down to 1.13
