About this Mod

Chat Opacity is a simple mod that allows the user to toggle chat visibility with a single keybind.

After installing the mod and dropping it into your mods folder, navigate to your keybinds and scroll down until you see "Chat Opacity Mod", and there you can change your keybind if necessary.

This mod does NOT erase the chat history, all it does is simply sets the chat text opacity to 0%.

Frequently Asked Questions

Chat Opacity server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is Chat Opacity compatible with fabric?

Chat Opacity officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Chat Opacity – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Chat Opacity consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
