LC²H V3.2.6 | Seam Ownership + Highway Support Fixes


V3.2.6 Overview

This update focuses on chunk seam reliability and structure continuity: less sliced roads/buildings at borders, better highway pillar behavior, and cleaner config/localization polish.


New Seam System (Implemented Differently)

  • Added a lightweight seam ownership + write-intent journal flow for cross-chunk edge writes
  • Reconciles border placements in a deterministic order to reduce perfect slice artifacts
  • Chosen over heavy global locking to avoid deadlock risk and keep throughput stable

Highway Support Improvements

  • Improved highway support/pillar depth handling for water/terrain crossings
  • Reduced cases where supports stop short and fail to visually reach ground
  • More consistent support generation across uneven terrain

Config + UX

  • Added/expanded config options for seam behavior and support-depth tuning
  • Improved descriptions so new seam/ownership/depth settings are clearer in the UI
  • Keeps advanced controls optional while defaults stay safe for most packs

Localization Pass

  • Improved Chinese translation wording/structure
  • Updated Lithuanian locale and synced missing fields
