What Is ClayGen and Why Your Minecraft Server Needs It
If you have ever run a Minecraft server with mcMMO, you might remember the classic mechanic where flowing water transformed gravel into clay. When that feature was removed, many server owners felt the loss of an easy, renewable clay source. ClayGen steps in to fill that gap, bringing back the gravel-to-clay transformation with even more flexibility. Whether you manage a survival world, a skyblock challenge, or a custom game mode, this plugin gives you precise control over how and when clay appears.
Three Modes to Match Your Playstyle
ClayGen does not force a single behavior on your server. Instead, it offers three distinct modes that you can switch between simply by editing a configuration file. Each mode creates a different gameplay rhythm, so you can pick the one that feels right for your community.
- mcMMO Style (Water Flow Activation) — Gravel turns into clay whenever water flows over or around it. This mimics the beloved original mechanic and requires no special block underneath.
- Activator Block Mode — Gravel only transforms when a specific block sits directly beneath it. By default, that block is brick, but you can change it to anything you like. This adds a building puzzle to clay production.
- Farming Mode — Gravel behaves like a crop. After a configurable delay, it gradually turns into clay. You can set minimum and maximum growth times, making clay farming feel organic and rewarding.
Deep Customization Through the claygen.ini File
Once ClayGen runs for the first time, it creates a claygen.ini file inside the plugins/ClayGen folder. Open that file, and you will find a clean set of options that let you tweak almost every aspect of the plugin. You can adjust the percentage chance for gravel to convert, change how many clay balls drop, and even enable a feature that increases clay drops the longer water runs over the block. The plugin automatically adds new settings when you update, so your config stays current without manual merging.
For those who love tinkering, the farming mode saves all in-progress gravel blocks across server restarts. That means if you set a long delay, a reboot will not reset anyone's hard work. Multi-world support is built in, although all worlds share the same configuration file, keeping management straightforward.
Installation and Getting Started
Setting up ClayGen is as simple as dropping the plugin jar into your server's plugins folder and restarting. After the first launch, the claygen.ini file appears, and you can immediately start editing values to suit your vision. If you are hosting a server locally or through a hosting panel, the process remains the same. Many players also experiment with mods and plugins on their own singleplayer worlds before rolling them out to a community. For that kind of testing, a modern launcher that handles modpack assembly effortlessly can save hours of troubleshooting. One such option is the foxygame.net launcher, which lets you download and manage mods directly from its menu, making it a convenient hub for trying out server-side plugins like ClayGen in a controlled environment.
Performance and Bug Fixes Over Time
ClayGen has matured through many versions, with each update addressing performance hiccups and edge cases. Early builds suffered from issues like gravel on the very edge of water flow not transforming, or blocks changing unusually fast. The developer steadily patched these, fixing server thread lockups and NextTickOutofSync errors that could crash a server. Version 1.2 resolved a StackOverflowError triggered by WorldEdit region regeneration, making the plugin compatible with world editing tools. Later updates also ensured that chunks stay loaded while gravel is turning into clay, preventing progress loss when players wander away.
Why ClayGen Stands Out Among Similar Plugins
Many plugins offer a single way to generate clay, but ClayGen’s three-mode design gives you room to grow. You might start with the simple mcMMO style for a nostalgia-driven server, then later switch to farming mode when players ask for a more agricultural feel. The ability to use lava as a flow trigger instead of water, configurable via the config, adds another layer of creativity. Because the plugin is lightweight and focuses only on this one mechanic, it avoids bloat and plays nicely with other world-altering plugins.
The changelog reveals a developer who listens: the percentage chance feature came from a Canary forum suggestion, the more-drops-over-time mechanic was a community request, and farming mode was built because users wanted a delayed transformation. This responsiveness means ClayGen will likely continue to evolve alongside Minecraft updates.
Final Thoughts
ClayGen revives a lost mechanic while giving server admins far more control than the original ever offered. Whether you want instant water-triggered clay, a puzzle with activator blocks, or a slow farming cycle, the plugin adapts to your vision. Its clean configuration file, automatic setting updates, and robust error fixes make it a reliable choice for servers running Minecraft 1.20.2 and beyond. If you miss the days when a stream of water could turn gravel into a valuable resource, ClayGen is the plugin that brings that magic back—and then some.
