Phantasium

Phantasium is a client-side optimization mod for Minecraft designed specifically for servers running ModelEngine, Nexo, ItemsAdder, and Oraxen. four popular plugins that spawn large numbers of display entities, armor stands, and custom packets that general-purpose optimization mods have no awareness of.

The mod works entirely client-side and requires no server-side installation. It automatically detects which plugins are active on the server you join and applies the relevant optimizations without any manual setup.

For players on custom RPG or survival servers, Phantasium can provide significant FPS improvements in areas with heavy plugin activity, particularly in towns, hubs, and combat zones where ModelEngine mobs and Oraxen/ItemsAdder furniture are densely placed. Expect the most noticeable gains in areas where many custom mobs are on screen simultaneously.

Phantasium is designed to run alongside general optimization mods like Sodium, EntityCulling, and ImmediatelyFast, covering the plugin-specific layer those mods cannot optimize.

Installation

Make sure you have the latest version of Fabric Loader and drop the mod into your mods folder. Fabric API is required. No additional setup or server-side installation is needed. Phantasium activates automatically when it detects a compatible plugin on the server you join.
