What is this?（用途）
This mod makes far-distance rendering work instantly on servers with pre-generated worlds: the server streams its raw region files (r.x.z.mca) to clients, and the client imports them through the official Voxy pipeline (WorldImporter) to build LoD data — so players see distant terrain without having to explore it themselves.
本模组让预生成世界的服务器玩家立刻获得超远渲染：服务器把原生区域文件发给客户端，客户端经 Voxy 官方导入管线转换为 LoD。
Features（功能）
- all mode (default per server config): send every region of the player's current dimension (full-map)
- radius mode (safe option): only send regions within N blocks around the player, nearest first
- Rate-limited chunked transfer (default 1 MB/s per player), incremental sync via client-side file cache (resume support)
- Progress shown in the action bar; graceful fallback when Voxy is not installed
- Server commands (OP):
/voxysync status,enable,disable,mode radius|all,radius <blocks>,sync,devtest
⚠️ Important warnings（重要说明）
- full-map mode (
syncMode: "all") exposes world data: MCA files contain chest contents, ores, hidden structures and entities. Only enable it on trusted servers. Radius mode is the safe default in code; full-map requires an explicitconfig/voxysync.jsonsetting. - Requires an unofficial Voxy 1.20.1 port on the client (not included here): the official Voxy on Modrinth supports 1.20.4+. The 1.20.1 build used by this server is a community port (
voxy-0.2.7-alpha, based on commit 9edc41be). This mod does not include or modify Voxy — it only calls its import API via reflection. - First full-map sync is large: ~20 GB at 1 MB/s ≈ 5.5 hours (configurable via
speedLimitKBps); resumable.
Dependencies（依赖）
