• Added structures/inactive support for keeping structures installed but ignored.
• Fixed several GUI layout and paging issues.

Changed bundled structure toggle (Bnd on/off in GUI Balance tab) to also remove bundled structures from GUI structure listing

Complete port of RCV 1.20.1 Forge v0.4.2.0 to 1.21.1 NeoForge.

added highlight to struct/schem selection in GUI

• reccomplex config folder and structure/schematic folders are now automatically created on launch

• structures can now sit in active/ folder instead of active/structures (which also works)

• Rewrote linked README to be GUI-first rather than command first.
• Expanded the in-game GUI with better structure editing tools.
• Added detailed transformer editing for supported RC transformers:   - terrain blending;   - natural-air cleanup;   - preserve-air behavior;   - ruins/decay settings.
• Improved script marker authoring:   - add, update, remove, and list weighted command entries;   - create simple child-structure spawners;   - create structure-list spawners using existing RC weighted structure lists;   - edit spawner shift, facing, rotation, mirror, and trigger settings.
• Improved /rc gui usability:   - cleaner Script editor pages;   - better Xform editor pages;   - clearer tooltips;   - truncated text now shows the full value on hover.
• Improved docs/help for transformer editing and script marker workflows.

Added

• Added admin command: /#structures locate <structure-id>
• Finds the nearest predicted Recurrent Complex natural/static structure spawn.

Usage

/#structures locate <structure-id> [--radius <chunks>] [--dimension <id>] [--from <x> <z>] [--unchecked]

Examples

/#structures locate RuinedTemple
/#structures locate RuinedTemple --radius 256
/#structures locate RuinedTemple -r 128 --from 0 0
/#structures locate RuinedTemple --dimension 0 --unchecked

Options

• --radius / -r: search radius in chunks. Default: 128.
• --dimension / -d: dimension ID. Default: your current dimension.
• --from <x> <z>: search from these coordinates. Default: your position.
• --unchecked: skip chunks ReC has already checked/generated.

• Added missing-block repair tools for old .rcst structures.

  • Missing blocks can now be replaced globally or fixed inside one editable structure.
  • New GUI workflow: /rc gui -> Gen -> Fix.
  • New commands: /rc missing ....

• Improved compatibility for imported legacy structures and schematics.

  • More old vanilla blocks now convert correctly to modern 1.20.1 blocks.
  • Old schematics now use the same legacy block conversion path as RC structure files.

• Improved stability for large old structure packs.

  • Deferred placement is safer around rail/redstone-like blocks.
  • Reduced repeated log spam from missing content and malformed legacy inventory data.

• Raised the editor/save size limit for large structures and loot tables.
• Added simple biome/dimension whitelist and blocklist options in config.
• Added simple biome/dimension ID/type controls in the structure generation GUI.
• Advanced biome/dimension expressions are still supported.

• Improved GUI tooltips and readability.
• Added support for standard biome/dimension syntax in config and GUI, alongside existing expressions.
• Added vanilla locate support for RC natural structures via /locate structure reccomplex:natural_structure.
• Added predictive /rc locate support for finding specific RC structures.
• Added natural structure spacing / anti-clumping controls.
• Fixed overly strict natural structure surface placement checks.
• Added /rc whatisthis and /rc here to identify recorded RC structures at the player’s location.
• Added unbound-by-default RC keybinds for browser, confirm, cancel, and undo actions.
• Renamed public config sections from legacy wording to cleaner worldgen/saplings/decorations/villages names, with migration for old keys.

v2.0.0.3 changelog:

• Fixed replacement blocks losing custom tile entity data. Custom NBT added to blocks like chests in the Replace transformer now saves and reloads correctly, instead of resetting after saving. Old/broken saved formats are still read for compatibility.

v2.0.0.1 changelog:

• Fixed a stack overflow crash caused by recursive worldgen decoration in certain modded biome generation setups.
• Added a guard to stop Recurrent Complex decoration from re-entering itself during nested decorate events.
• Prevented structure placement checks from triggering extra chunk loading/population when chunk-generation avoidance is enabled.
• Reduced the chance of cascading worldgen, lag spikes, and related generation instability in large modpacks. Note: with avoidPlacerChunkGeneration enabled, some placements near chunk borders may now be skipped rather than forcing unsafe chunk probes.

v2.0.0.0 changelog:

Fixes:

• Fixed generationInfoID lookup and persistence across NBT and structure operation paths, so generation metadata is now preserved correctly.
• Corrected Entry.equals behavior in world structure generation data, preventing invalid comparisons and related cache/key issues.
• Improved handling of unknown or missing world data, especially loot and item-related content, including proper cache invalidation when content becomes available again.
• Improved invalid entity ID handling with a safer fallback path.
• Fixed stale universal transformer preset state after config reloads.
• Fixed chat command functionality on Java 24+

Performance and Stability:

• Improved thread safety in structure generation by making caches concurrent, adding per-chunk locking, and tightening cache construction safeguards.
• Improved chunk-lock lifecycle handling to make generation more reliable under concurrency.
• Reduced repeated warnings and lookup cost by caching missing presets and missing entities.
• Reduced worldgen log spam and improved diagnostics for missing-content errors.
• Reduced overhead in structure hook processing, reflective lookups, checked-chunk tracking, and chunk packing logic.
• Improved patterned generation and loot-related runtime behavior.

Worldgen and Placement:

• Improved selective placer filtering for more stable surface candidate selection on uneven terrain.
• Fixed ray-based placement failures so invalid placements are no longer reused.
• Improved ray averaging precision to reduce placement instability from tiny floating-point differences.
• Added a config option for vertical spread tolerance in ray hits, making uneven-terrain placement more predictable (rayAverageMaxHeightSpread).
• Tightened uneven-ray validation and improved related feedback.
