Features
Inventory Verifier addon to Litematica's Schematic Verifier
- Conveniently displays the difference between the expected and found inventory contents side-by-side.
- Has semantic slot highlighting (view feature
inventoryScreenOverlayfurther down). - Turning on
verifyItemComponentswill require item components to match and will also visualize them in the item tooltip for you to compare. - Enables schematic creators to use item predicates - a flexible way to specify what properties items should have. Here's an impractical but exhaustive example via Misode's handy generator.
Check out the feature's showcase video:This feature only works if your server has Servux (or PCA Protocol in 1.20.1-4), or you have nbt query permissions (e.g. by being an operator or installing a permissions mod/plugin), or you're in Singleplayer.
On Multiplayer, make sure you have enabledentityDataSyncandentityDataSyncBackupin Litematica's settings.Sync WorldEdit selection

This only works for .litematic files.
