ClayGen is a plugin I made to turn gravel into clay after it was removed from mcMMO. There are three different modes:

1. Turn gravel into clay whenever water flows over or around it (mcMMO style)
2. Only when a certain block is below the gravel block (the default is Nether Bricks).
3. Farming mode: Sets a configurable delay before the gravel turns into clay. Just like any other crop in Minecraft.

To change the behavior of the plugin just edit the claygen.ini file that it creates on first run under plugins/ClayGen.

Comments, suggestions and bug reports are all welcome.

Features:

• Turns Gravel into clay with or without an activator.
• Configurable option to only change a certain percentage of the gravel into clay.
• Change the default number of clay drops
• Saves the blocks turning into clay in farming mode across server reboots.
• Configurable option to have the clay drop more clay balls the longer water runs over the clay.
• Multi-world support (although all worlds share the same config)
• Editable config file.
• Automatically adds new settings to config file when updating.
