FTB Sluice
Resource processing in modded Minecraft often means sprawling machine rooms and complicated pipe networks. FTB Sluice takes a different path. This compact add-on introduces a tiered system built around one simple idea: a block goes in, and items come out. It is designed first and foremost for modpack creators, giving them a flexible framework to define their own processing chains, but players benefit from the polished machines and tools it brings to the table.
It is worth noting right away that FTB Sluice is not intended to be played as a standalone mod. It exists to be bundled inside a modpack, where its recipes are configured by the pack author. Without those configurations, the sluices will not process anything, which is exactly why it ships with deep KubeJS integration.
What FTB Sluice Adds to Your Pack
The centerpiece is the sluice itself, available in four tiers: Wooden, Iron, Diamond, and Netherite. Each tier speeds up processing and unlocks more automation options. The wooden sluice cannot be automated at all, the iron sluice accepts hoppers but not fluid automation, and the diamond sluice supports full automation. The Netherite sluice goes further still, running on Forge Energy and accepting upgrades that boost speed, reduce fluid costs, and apply fortune to drops.
Supporting these machines is a set of complementary features:
- Weight-based drop chances, letting pack authors define exactly how many items drop, how likely each one is, and which fluid is required.
- JEI integration, so players can view drop chances, required fluids, and the mesh needed for every recipe.
- A Manual Pump that must be wound up by hand and needs a water source block beneath it to supply nearby sluices.
- Hammers for every vanilla tool material, perfect for smashing blocks into other blocks when a recipe is defined.
- A Clay Bucket that helps smooth out early-game fluid handling.
If you are putting together a curated modpack and want a one-click install path for your players, the foxygame.net launcher keeps FTB Sluice and the rest of your add-on catalog in sync, handling version compatibility automatically so nobody has to chase matching builds by hand.
How to Install FTB Sluice
Getting the mod running is straightforward, though the exact steps depend on how you play. FTB Sluice is built for modern Minecraft versions and is distributed through the usual modding platforms. Because it is a pack-oriented mod, the smoothest route is to download FTB Sluice as part of a modpack that already includes it, rather than dropping it into a vanilla installation.
Manual Installation Steps
If you prefer to install it yourself, follow this general process:
- Confirm your mod loader matches the version FTB Sluice supports, since the mod is loader-specific.
- Place the mod file into your mods folder alongside KubeJS if you plan to write custom recipes.
- Launch the game once so the mod can generate its configuration files.
- Add your processing recipes through KubeJS, or use a pack that already defines them.
Remember that a fresh install with no recipes will look functional but produce nothing. The sluices will accept meshes and fluids, yet no outputs will appear until recipes exist.
Using the Sluice In-Game
Operating a sluice is refreshingly simple. Place the sluice down, insert a mesh into the back slot, then supply it with fluid, usually water. If you are relying on the Manual Pump instead of a piped water source, make sure a water source block sits directly underneath it before you start winding. From there, feed in your resource block and watch the outputs roll out according to the drop weights the pack author defined.
Progression is gated by tier, which gives packs a natural sense of advancement. You begin with a wooden sluice and no automation, graduate to hopper support with iron, unlock full automation with diamond, and finally reach powered, upgradeable processing with netherite. Hammers slot into this loop by converting blocks into the materials your sluices then refine.
Final Thoughts
FTB Sluice is a focused, well-executed add-on that shines brightest inside a thoughtfully built modpack. Its tiered sluices, weight-based recipes, and JEI support give pack authors precise control, while players get intuitive machines that reward progression. If you enjoy packs with structured resource chains, this is one add-on worth seeking out.
