JEI Drops

JEI Drops is a JEI addon for Minecraft Forge 1.20.1 that scans block loot tables and shows block drops as JEI recipes/usages.

It can show drops from normal breaking, hand-breaking, shears, Silk Touch, Fortune, and other tool-sensitive loot results where they can be detected.

Important Notes

This mod is still alpha and not perfect.

After a world/server loads, JEI Drops needs to scan the loaded block loot tables. This can take a while, and on large modpacks or slow systems it may take several minutes or longer. After the scan finishes, the result is cached and synced to players when they join or when a new scan completes.

The cache is written per world to:

serverconfig/jeidrops/blockdrops-cache.json

On a dedicated server this is usually:

world/serverconfig/jeidrops/blockdrops-cache.json

Limitations

JEI Drops is not guaranteed to detect every drop from every block in every modded pack.

Known weak spots:

Some drops depend on real block entity / tile entity data.
Some drops depend on world state, NBT, random mod logic, fake players, dimensions, biome data, or other runtime-only context.
Some modded loot functions cannot be safely simulated.
Very rare random drops may be missed or estimated inaccurately if they do not appear during sampling.
Exact drop chances are based on loot simulation/sampling, so they may not always be perfect.
Some blocks may be skipped or simplified if their loot logic cannot be safely evaluated.
Large modpacks can produce a big cache and long scan times.

The mod should not intentionally crash your game/server, but it is alpha software and it touches a lot of modded loot code. Broken or unusual loot functions in other mods may still cause issues. Test it on your pack before relying on it.

Some mods may log warnings during loot simulation, especially if their loot functions expect real block entities or special world data. JEI Drops tries to avoid or suppress this where possible, but some warnings may still appear in certain packs.
