Simplexium
Simplexium is an all-in-one NeoForge expansion that combines automation, world interactions, mining changes, farming and visual tweaks in one configurable mod.
What it does
The mod collects automation, smart interactions, mining mechanics, dynamic farming and visual camera filters into a single configurable package that goes well beyond quality-of-life changes. Each feature can be turned off on its own, either in the in-game config screen or in the simplexium-common.toml file, so a player can keep vein mining and disable auto-swap or drop penalties. Files cover 1.21.1 – 1.21.11 and are released under All rights reserved, so the code is not open source. Every player and the server need a copy of the mod.
Key features
Automation
Automated processes that handle repetitive tasks, paired with smart interactions with blocks and the world.
Mining mechanics
Vein mining and related changes to how blocks break and drop, which can be disabled individually.
Visual camera filters
Camera filter effects that change the look of the view, alongside dynamic farming options.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
