Tag Stack
📦 Customize item stack sizes using tags! 📦
The Tag Stack mod allows you to control how many items can stack together by using simple item tags. Perfect for modpacks or servers where you want to tweak item stack size.
Features
Tag-Based Stack Sizes: Change stack sizes by applying these tags to items:
tag_stack:stackable_to_1tag_stack:stackable_to_2tag_stack:stackable_to_4tag_stack:stackable_to_8tag_stack:stackable_to_16tag_stack:stackable_to_32tag_stack:stackable_to_64
Special Bucket Support: On versions 1.20.1-1.20.4 and 1.21.1-1.21.2, includes special handling for:
- Vanilla buckets
- Dispensers
- Lumisene bucket (Supplementaries)
- Wooden buckets (Let's Do Meadow)
Actually reloads: Changes apply when reloading datapacks (clients need to rejoin to see changes).
