f. Methods for Calculate Max Stack

Each cargo has a maximum stacking layers value for each placement method.

1) "Per-type max layer constrain mode": only restricts how many layers any single cargo placement can stack; there is no restriction across different cargo types.

2) "Same stack code treat as one type mode": restricts the total layers when different cargo types are stacked together; cargo with the same stack code is treated as one type. See Stack code above.

Example: many different-size cargo items must be loaded with the requirement that all cargo, however stacked, must not exceed 5 layers. Set the same stack code for these cargo items and set the maximum stacking layers(Max Stack) of each to 5, then choose "Same stack code treat as one type mode".
