Overview

LunaBlur adds a lightweight fullscreen motion blur effect without going for the heavier cinematic style some other blur mods use. The goal is simple: keep the game feeling smoother in motion while staying easy to use and easy to drop into a normal Fabric setup.

Frequently Asked Questions

lunablur 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 lunablur compatible with fabric?

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

Server lagging with lunablur – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if lunablur 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.
