Requirements
Before installing NeonFX, make sure your server meets the requirements for your Minecraft version.
Server Software
NeonFX is designed for Paper servers.
Use the NeonFX build that matches your Minecraft version. Each supported version family has its own JAR and resource pack.
Supported Versions
NeonFX currently supports:
- Minecraft 1.21.x
- Minecraft 26.1.x
- Minecraft 26.2.x
- Minecraft 26.3.x
Always use the NeonFX JAR built for the version family your server is running.
Java Version
The required Java version depends on your Minecraft version:
- Minecraft 1.21.x: Java 21
- Minecraft 26.x: Java 25
Using the wrong Java version may prevent Paper or NeonFX from starting correctly.
Client Requirements
Players do not need to install any Minecraft mod.
NeonFX works with vanilla clients.
A resource pack is used for the custom NeonFX models. The server can continue running without it, but players will use the fallback renderer if the resource pack cannot be loaded.
Dependencies
NeonFX does not require another plugin to work.
Some plugins may be detected as optional integrations, but they are not required for normal NeonFX operation.
