JEI Crafting Tree

Selecting an ingredient in a recipe screen expands it into its own sub-recipes, so a full chain of crafts can be read at once. Unresolved inputs are expanded automatically only when Just Enough Items exposes exactly one usable recipe for them. Results can be shown as a normal graph or with layers merged into one material view.

When a route leads back to a material already in the tree, expansion stops at that point, the affected incoming edge is highlighted and a cycle diagnostic is reported instead of recursing indefinitely. Several named production targets can be kept in one session, and they draw on a shared global material ledger, so overproduction in one branch can cover a need in another. Secondary outputs and byproducts are credited back to that pool. The planner can allocate available inventory and produce an ordered execution checklist.

The mod requires Just Enough Items (JEI). It works standalone, and its planning model does not depend on AE2. Optional AE2 backends such as AE2 Utility add exact-pattern hints, encoding upload and substitution controls, and an AE2 compatible backend can include a compact pattern node inspector. Without such a backend, the AE2 integration is unavailable. The mod is released under the MIT License and is open source, and its source code is public. Files target NeoForge for 1.21.1 only.
