Recurrent Complex Volts
structure generation for modern minecraft
Обновлён 6 июля 2026 г. · опубликован 24 мая 2026 г.
Continuation of Recurrent Complex by Ivorius
Recurrent Complex is one of Minecraft's most advanced and complete structure-generation mods.
- ~200 bundled structures including ruins, castles, trees, villages, dungeons, mazes, etc.
- Dynamic variation including loot generation, randomized ruination, and scripted multi-piece systems
- Natural terrain blending, and integration with vanilla systems such as trees, villages, saplings
- Complete customization: create, import schematics, and share your own structures
- Extensive in-game GUI for configuring every aspect of the mod and your structures

1.20.1 Forge / 1.21.1 NeoForge / 26.1.2 NeoForge (v.0.6.0.x):
- Includes all original bundled structures.
- Supports old RC .rcst structure files, with modern block conversion and safe missing-mod fallback.
- Adds /rc gui for browsing, previewing, exporting, editing and repairing structures in game.
- Includes structure authoring tools: selection items, schematic import/export, generation presets, transformer presets/details, biome/dimension rules, script marker editing, missing-block repair and loot table editing.
- Create schematics are importable and functionality is supported for worldgen.
- Built for modpacks: compatibility audits, missing-block reports, clear diagnostics, safe missing-content handling, configurable worldgen frequency/spacing, and vanilla /locate support for RC natural structures.

1.12.2 Forge (v.2.0.0.6) (requires IvToolkit):
This version is intended as a drop-in replacement for the original Recurrent Complex 1.12.2 mod.
- Fixed command compatibility with Java 24+
- Fixed severe lag caused by structures referencing blocks from uninstalled mods
- Improved performance through various changes and optimizations
- Improved structure placement logic, especially on rough terrain and water (configurable)*
- Fixed bug where structures would sometimes spawn one block lower, particularly on water
- Fixed bug where structures occasionally spawn in the sky
- Fixed custom chest tile entity data being lost when using replace transformers
- 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
- Added /#structures locate for finding predicted RC structure locations
*rayAverageMaxHeightSpread is the new config option, which improves/filters placement on rough terrain. This will also reduce structure frequency slightly. Increase value to soften effect, set to 0 to disable completely (reverting to original RC behavior).

Note for 1.12: if you have RLTweaks installed, make sure to disable the patches for Recurrent Complex, as they conflict with this mod's code and are unnecessary.

0.6.0.0Релиз26.1, 26.1.1, 26.1.2 · 6 июля 2026 г.
Recurrent Complex Volts 0.6.0.0
Worldgen And Villages
- Added a configurable RC village budget. Villages now have a bounded total RC-piece budget instead of only relying on per-piece weights and caps.
- Improved RC village reliability in modern Minecraft villages, including better village detection, bounded retries, more stable anchoring near vanilla village pieces, overlap checks, and persisted per-village placement caps across reloads.
- Added
villages.attemptChance, default0.35, to reduce average RC village-piece density without lowering the hard per-village budget.
Performance And Placement
- Added faster loaded-placement handling for active deferred structures and chunk-complement placements. Loaded structures and loaded chunk slices should now complete much faster while still respecting chunk safety.
- Added worldgen structure decode and biome-prep caches to reduce repeated work during generation.
- Accepted natural, village, and decoration placements are now parked and resumed more reliably instead of being lost under queue pressure.
- Improved deferred placement safety and log behavior, with fewer repeated warnings during normal worldgen.
Commands And Authoring
- Added
/rc generateas the modern old-style/#genequivalent for explicit natural structure generation, with preview-first behavior for players and/rc confirm//rc cancel.
Worldgen Behavior Fixes
- Fixed biome sampling in several worldgen paths so surface biome rules are checked at the actual surface instead of
Y=0. This prevents cave biomes from affecting surface trees, villages, and natural structures. - Restored legacy tree support behavior on modern versions where vanilla dirt tags changed, fixing RC trees failing to place on normal growable surfaces.
- Unified natural surface roughness under
worldgen.maxSurfaceDelta, default7. - Added snowy-environment blending for natural and village structures, including snow on exposed saved ground and snow-supporting roof/top surfaces.
- Fixed legacy double-door placement so upper/lower halves no longer mismatch open/closed state.
Balance And Bundled Structure Tuning
- Reduced default RC decoration tree pressure with
decorations.treeChunkChance=0.10,decorations.treeBaseWeight=0.03, and at most one RC tree replacement attempt per chunk. - Tightened biome metadata for
BirchTreeBigandQuakingAspenso birch/aspen-looking trees appear less often in unsuitable climates.
Notes
- Existing generated config files are not automatically rewritten. Delete/regenerate
reccomplex-common.tomlor update values manually to get new defaults.

- Survival players can sneak-right-click a compatible inventory to redeem a loot tag.

- Full inventories no longer cause loot tags to be consumed or existing items to be overwritten.
