RealWeight

Introducing the Weight Mod for Minecraft. FULLY CUSTOMIZABLE, COMPATIBLE WITH Create(Aeronautics) and Legendary Survival Overhaul. Now you can't carry 100,000,000 metric tons in your inventory—you're an ordinary person with ordinary physical capabilities. The weight of an item depends on the armor's appearance, type, material, and other factors, as well as the block's density and condition. For now, you can't level up your physical strength, but that feature will be added in future updates!
