ItemStackExporter
ItemStackExporter saves the blockstates and item states of a running game to files, so tool and shader developers can reuse them.
What it does
Exporting block and item states by hand takes long when a pack needs hundreds of entries. The mod automates that step: a configurable key, F8 by default, starts an export, and a keypad multiply key opens the output as a JEI page. Saved states are written in a Modname:blockname format inside the config directory, which suits pack and shader development where the data feeds into other tools.
Required dependencies are Just Enough Items (JEI) and Roughly Enough Items (REI). The mod runs on the client alone, so single-player and multiplayer clients need it while servers do not. Files are published for Fabric, Forge and NeoForge across four game versions, 1.16.5 – 1.21.1, with the newest NeoForge build targeting 1.21.1. The code is available under a Creative Commons Attribution 4.0 license and is not open source.
