About this Mod

This mod adds clean, flexible conveyor belts for Minecraft 1.21.1, compatible with both Fabric and NeoForge. It’s designed to work seamlessly with any item storage mod. The mod is still in beta, please report any issues you find.
🚚 Features:
- Adds a new Conveyor Belt item, plus optional Support and Chute blocks.
- Fully dynamic spline-based belts: Only the start and end need to be placed on blocks. Everything in-between can curve, bend, and twist freely.
- Item transfer speed: ~1 stack per second.
- Smart overflow handling: If the destination is full, items visibly pile up on the belt.
- Shader-compatible: Works with iris and oculus shaders.
- Easy filtering: Click a conveyor chute with an item to set it as filter. Also works with the Smart Filters from the FTB Filters mod.
🛠️ How to Use
- (Optional) Place Chute blocks where the belt will start and end. These can also be auto-placed when using the belt item.
- (Optional) Add Support blocks anywhere along the path to shape the belt's curve.
- Right-click the belt item on a starting inventory (e.g., a chest).
- Walk to the destination inventory and right-click it to finish the belt.
The belt path will auto-connect between the two points!
