Features
- Supports mismatched input and output belt speeds
- Helpful for scenarios such as multiple slow belt inputs feeding a single high-speed output
- Balances multiple inputs and outputs evenly using round-robin
- Configurable output lanes, facilitating compact and efficient belt utilization
- Supports blueprinting and copy/paste of ports
- Can be used to span gaps in space platforms
Notes
- Each surface has its own distinct network - items do not route between surfaces
- Items have realistic travel times for balance
Work items
- Item stacks are flattened when loaded into an underground network, but they should be preserved
- Updated graphics for all rotations and belt speed options
