Block Swap Reblocked

Block Swap Reblocked lets you replace any block—or specific block states—with another to unify duplicates across mods. Use it to merge overlapping ores or wood types from big modpacks, both in new worldgen and (optionally) existing chunks.

Why you’d want this
•  Consolidate duplicate content (e.g., multiple coppers/logs) into a single canonical block for cleaner recipes and progression.
• Remove certain blocks from a world

What it does •  Block and state swapping: map Block A→Block B, or map specific BlockState→BlockState.
•  Property carry-over: preserves matching state properties (e.g., log axis) when swapping.
•  Worldgen and existing worlds: swaps apply during world generation; you can also enable per‑block retrogen to update already-generated chunks as they load.
•  Player placements: optionally replace when a player places the old block (enable per block).
•  In‑game editor: browse all blocks, set replacements, and toggle “Retro” (retrogen) and “Player” per block.
◦  Forge: open via the Mods list config screen.
◦  Fabric: supports Mod Menu.
•  Lightweight: designed for minimal overhead; retrogen runs only when enabled.
