Recurrent Complex Volts 2.0.0.9

• Fixed legacy entities such as item frames, armor stands, chest minecarts, and zombie villagers being removed from structures.
• Fixed modern and legacy RC loot markers being removed, restoring missing structure loot.
• Fixed legacy entity IDs inside mob spawners.
• Improved compatibility with modded tile entities by validating them without constructing their classes.
• Preserved custom NBT data and spawner settings during sanitization.
• Missing content from mods that are not installed is still removed, retaining the sanitizer’s major world-generation performance improvements.
• Sanitizer caches will automatically rebuild once after updating.

Existing generated structures are not changed retroactively. Original structure files remain untouched, and structures generated after updating will receive the fixes.

Fixed issue #3

• Bundled structures were being stripped of some of their TileEntity data by the launch sanitizer.

This has now been fixed both for bundled structures and for any structures with pre-1.11 data. Damaged caches will regenerate.

Improved large-structure worldgen performance by optimizing snowy-environment blending. Snow caps now process only exposed surfaces in each affected chunk instead of repeatedly scanning the entire structure, without changing their appearance.

Recurrent Complex Volts 2.0.0.7

World Generation

• Increased the default maximum average-ray terrain height spread from 4 to 7, allowing large structures to generate more reliably.
• Fixed child structures selecting the wrong fixed-orientation variant when their parent was rotated or mirrored.
• Fixed non-rotatable child structures being incorrectly rotated during placement.
• Fixed fixed-facing village buildings being permanently discarded after encountering an incompatible road direction.
• Improved failure handling when a custom village component cannot be created.
• Restored witch-hut detection through RC’s scattered-feature wrapper, fixing witch spawning and compatibility with modded implementations such as Biomes O’ Plenty.

Note: Existing configs retain their current rayAverageMaxHeightSpread value. The new default of 7 applies to newly generated configs.

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, default 0.35, 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 generate as the modern old-style /#gen equivalent 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, default 7.
• 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 BirchTreeBig and QuakingAspen so birch/aspen-looking trees appear less often in unsuitable climates.

Notes

• Existing generated config files are not automatically rewritten. Delete/regenerate reccomplex-common.toml or update values manually to get new defaults.
