fringe storm
Cuts each belt separately, and cleanly separates both halves while maintaining lane order from left to right! Also maintains original shape and rotation.
Give this whatever mixed inputs you want, and it will process them all separately. If one lane empties or stalls, the others will still move at full speed. Triple floor variant can process up to 12 different types of shapes at once!
Note that this is a zero loss operation to keep your belts packed tight, so there is no trash/stall protection for one single lane, if you stop using one half of the same shape.
