Supplementaries is a Java Edition decoration and utility mod that adds over 50 handcrafted blocks and items designed to fit the base game's visual style. Signposts, glass jars, faucets, planters, spring launchers, sconces, and hourglasses all follow vanilla crafting conventions and work on both client and server. It runs on Fabric, Forge, and NeoForge from Minecraft 1.16.5 through 1.21.1.
What Supplementaries Adds
The mod covers several categories of vanilla-style content. Each item uses standard materials and integrates without texture clashes in lightly modded or vanilla-plus setups.
- Signposts: placeable directional signs that store custom text and point toward named destinations.
- Glass jars: storage containers that display their contents visually when placed on a surface.
- Faucets: fluid transfer blocks that pour water or other liquids from a source into a container below.
- Planters: decorative containers that grow flowers and crops with a smaller footprint than vanilla farm layouts.
- Spring launchers: redstone-compatible launch pads that propel entities and items upward.
- Sconces and light sources: wall-mounted and freestanding lighting suited to stone and wood builds.
- Weather vanes, hourglasses, globes, slingshots, and doormats: ambient items for builds and interiors.
How to Install Supplementaries
- 1.Install a supported mod loader for your Minecraft version: Fabric with Fabric API, Forge, or NeoForge.
- 2.Download Moonlight Lib for the same loader and Minecraft version and place it in the mods folder.
- 3.Download Supplementaries from Modrinth for the same loader and Minecraft version.
- 4.Place the Supplementaries .jar in the mods folder alongside Moonlight Lib.
- 5.Launch Minecraft through your mod loader profile. Both files must be present for the game to start.
Multiplayer and Server Support
Supplementaries requires installation on both the client and the server. Servers running Fabric, Forge, or NeoForge can add the mod alongside Moonlight Lib using the same steps as single-player. Clients connecting without the mod installed may see missing block models or fail to connect depending on how the loader enforces required server-side mods.

Questions about this entry.
How do I install Supplementaries?
Install a compatible mod loader (Fabric with Fabric API, Forge, or NeoForge), then download both Moonlight Lib and Supplementaries from Modrinth for the same Minecraft version and loader. Place both .jar files in your mods folder and launch through your loader profile. Moonlight Lib must be present or the game will not start with Supplementaries loaded.
Does Supplementaries work with Fabric, Forge, and NeoForge?
Yes. Supplementaries ships a build for each of the three major mod loaders. Download the build that matches your loader. Fabric users also need Fabric API installed. Quilt is not listed as a supported target.

Supplementaries requires Moonlight Lib as a hard dependency on all loaders. No other mods are needed. Some integrations with other mods from the same developer exist but are entirely optional and do not affect the core feature set.
Does Supplementaries work on multiplayer servers?
Yes, and server installation is required. Both the server and each connecting client need Supplementaries and Moonlight Lib. Fabric servers also need Fabric API. Clients missing the mod may see missing model errors or fail to connect.
