Every item
Item Stack Size Multiplier (ItemStackSizeMultiplier) on the Item Settings card multiplies the stack size of every item.
Single items
- Open the Item Max Quantity card.
- Pick the item from the list.
- Set Max Item Quantity. With Ignore Global Multiplier on, the item stacks to exactly that number.
Weight
Bigger stacks don't change an item's weight. Raise weight on Player Stats or Dino Stats if players can't carry what they gather.
Questions
Why didn't the stack multiplier change some items?
Some items keep a stack size of 1, such as weapons and saddles. Items with their own value on the Item Max Quantity card use that value instead.
