# Blueprint Nexus — Update Version 1.4.0

We are excited to release **Version 1.4.0** of Blueprint Nexus! This major update brings massive improvements to custom structure generation, resolves long-standing bugs, boosts server stability, and adds robust security features for server administrators.

Here is the complete overview of what's new in this release:

---

### 🛡️ For Server Administrators (Admins)

* **Strict Command Permissions**: 
  * All `/bn` commands (including `/bn list`, `/bn tp`, and `/bn reload`) are now fully secured under the `blueprintnexus.admin` permission node.
  * Ordinary players will no longer see these commands in their tab-completion menu, and any direct execution attempts will be blocked by the server's permission handler. This keeps all structure spawn coordinates and admin options 100% secret and safe.
* **Disabled Direct Local Scanning (Safer Spawning)**:
  * Completely disabled direct scanning of local folder structures. Legacy local filesystem scanning bypassed standard heightmap alignment, which sometimes caused structures to spawn incorrectly (e.g., embedded inside mountains or trees).
  * All structures are now loaded securely through official Hytale **Asset Packs**, ensuring flawless world-gen alignment and correct biome integration.
* **Robust Teleportation without Crashes**: 
  * Upgraded the `/bn tp` command to use Hytale's official thread-safe ECS teleportation system. Teleportation requests are now safely queued and executed on the main `WorldThread`, completely eliminating concurrent ForkJoin thread assertion crashes.
* **Clean Console Startup Logs**: 
  * Resolved a double-registration bug where the plugin registered structures twice during the server boot process. Your console startup logs will now be clean and free of double-reload spam!

### 🎮 For Players & World Generation

* **Perfect Terrain Carving (No Floating Dirt/Stone)**: 
  * Fixed an annoying bug where vanilla terrain blocks (like stone, dirt, and gravel) would spawn inside archways, windows, or portal frames of custom structures.
  * Technical void blocks (`hytale:editor_empty`) and explicit empty spaces (`blockId 0`) are now correctly placed as pure air (`BlockType.EMPTY`). Inside rooms, archways, and window openings will now look completely clean, just as the builders intended!
* **Fixed Disappearing Water & Fluids**: 
  * Resolved a critical issue where fluids (like water inside fountains, decorative pools, or channels) failed to spawn if a structure crossed a chunk boundary. 
  * Water and other fluids are now safely deferred and perfectly rendered once the chunk is initialized!
* **Seamless Structure Rendering (No More Half-Cut Buildings)**: 
  * Fixed a bug that caused massive composite structures to get sliced in half at chunk borders. 
  * The search boundaries have been expanded to `1024` blocks, ensuring that very large structures, complex castles, and child prefabs render completely and beautifully across chunk borders without causing any server lag.
