About this Mod
What is DucLib?
DucLib is a library mod that you can use to add models and animations into the game. Unlike regular java models, you can use per face uv (also box uv if you want to). It also supports animations, which are easy to implement due to the fact that you can start and stop them from anywhere (so even in goals if you really want to!).

DucLib server crashes on startup – what to do?

Server lagging with DucLib – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if DucLib consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
