About Recurrent Complex Volts
From ModrinthContinuation of Recurrent Complex - tons of structures, fully customizable
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/Fabric / 1.21.1 NeoForge/Fabric / 26.1.2+ NeoForge/Fabric (v.0.7.3.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.2.0.1.2) (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
- Greatly 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 <structure-id> for finding predicted RC structure locations
- Fixed some other bugs (see changelogs for full details)
*rayAverageMaxHeightSpread is the new config option, which improves/filters placement on rough terrain. This will also reduce structure frequency slightly. Decrease value to strengthen effect, set to 0 to disable completely (reverting to original RC behavior).
