Do I need Fabric API installed?
Some environments require Fabric API as a dependency. If Minecraft crashes on launch with Nova Client installed, download the Fabric API .jar matching version 1.21.11 and place it in your mods folder alongside Nova Client.
How do I update to a newer Nova Client build?
Download the new .jar from the Downloads page. Remove the old Nova-Client-*.jar from your .minecraft/mods folder and replace it with the new one. No other changes needed.
Usage
How do I open the Nova Client GUI?
After joining any world or server, press Right Shift to open the Nova ClickGUI. Use the category panel on the left to switch module groups, then click any module row to toggle it on or off.
What is the Donut module category?
The Donut category contains modules tuned specifically for DonutSMP and Donut PvP environments. These include server-specific features like FakeScoreboard, AntiBlockRotate, SilentHomeSetter, and HoleESP.
Can I use CloudConfig to sync my settings?
Yes. The CloudConfig module (available in both the Donut and Misc categories) syncs your module configuration to a cloud profile, letting you restore your setup across reinstalls or on different machines.
What does StreamerMode do?
StreamerMode hides sensitive information — coordinates, server IP, player names — making it safe to stream or record without leaking private data.
Troubleshooting
The game crashes when I load with Nova Client installed.
Check these in order:
1. Confirm you're using Minecraft 1.21.11 with Fabric Loader — not a different version.
2. Install Fabric API for 1.21.11 in your mods folder.
3. Make sure no other conflicting mods are loaded.
4. Try a fresh Fabric 1.21.11 profile with only the Nova jar + Fabric API.
The GUI key (Right Shift) doesn't open the menu.
Make sure you're in a loaded world or server — the GUI cannot open from the main menu. If another mod has claimed Right Shift as a keybind, there may be a conflict. Check your Minecraft Controls settings for keybind clashes.
A module I enabled doesn't seem to be working.
Some modules are server-dependent (e.g., Donut category features only work on DonutSMP). Ensure you're on a compatible server and that the module's green ON indicator is lit in the GUI.
