About this Mod
ModularUI
This is the ultimate GUI mod for minecraft.
History
The first time I encountered a form of a ModularUI was in GTCE in version 1.12.2. The concept was great. Much less boiler plate code. No GUI texture sheets. And more. However there were a lot of problems. There were lots of bugs. The code was a mess and compat with other mods such as Inventorytweaks was very difficult.
Then GTCEu was made as a fork of GTCE. The UI code received some improvements, but somehow it got even messier. At that point CleanroomMC already decided to make a reworked, standalone version of ModularUI. So I volunteered to do the job. And I did.
On May 22nd 2022 the first version was released on CF. It was a huge improvement compared to GTCE/GTCEu, but I still was not happy enough. So a few updates and month later i started to rewrite some portions of the mod. However the rewrite became so large that it was almost a full rewrite. Was it worth it? I don't know, but now I'm happy with the result.

ModularUI server crashes on startup – what to do?
Most common cause: wrong forge 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 (1.20.1). You can switch loaders with one click in the panel.

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