ItemPhysic Mod FAQ
10 questions players actually ask, answered.
How do I make dropped items stack together instead of scattering everywhere?
ItemPhysic handles this automatically once installed — dropped items of the same type will merge into a single stack on the ground rather than spreading out. If items still scatter, check that the mod is actually loaded and that no other item-merging or physics mod is overriding it.
How do I turn the ItemPhysic animations on or off in-game?
Open the mod's config screen from the Mods list or the in-game config menu and look for the animation toggles. You can disable the drop animations, the item rotation, or the whole physics effect without uninstalling the mod.
What's the difference between the Full and Lite versions of ItemPhysic?
The Full version includes the complete animation and physics overhaul, while the Lite version keeps the core stacking and drop behavior but strips out heavier visual effects. Pick Lite if you're on a low-end machine or a server where performance matters.
Why are my items floating in the air or stuck after installing ItemPhysic?
This usually means another mod is conflicting with ItemPhysic's physics handling, or the mod failed to load properly. Remove other item-physics or drop-animation mods, then reload the world and check the config for any disabled physics options.
Do I need to install anything else for ItemPhysic to work?
ItemPhysic requires the matching mod loader for your version, and on some versions it also depends on a separate animation library. Check the mod's dependencies on its download page before launching.
Can I use ItemPhysic on a server with friends?
Yes, but every player who wants the visual effects must install it client-side, and the server needs the mod too if you want the stacking behavior to be consistent. If only some players have it, they'll see different drop behavior than everyone else.
Does ItemPhysic work with other item or inventory mods?
It generally plays fine with inventory and storage mods, but mods that also change dropped-item behavior — like item-merging or custom drop animations — will often conflict. Test one at a time and disable overlapping features in the config.
Will ItemPhysic hurt my FPS or cause lag?
The Full version adds extra animation and physics calculations that can cost performance on large drop piles or busy servers. If you notice lag, switch to the Lite version or turn off the heavier animation options in the config.
How do I stop items from stacking together if I don't want that?
Open the ItemPhysic config and disable the item-stacking or drop-merging option. This keeps the animation changes but returns vanilla-style scattered drops.
Why don't my items stack when I break a chest or a shulker box?
ItemPhysic merges like items on the ground, but items with different NBT data — such as enchanted gear or renamed items — won't combine even if they look identical. This is expected behavior, not a bug.
