Voxy Server Side Forge / NeoForge

Voxy Server Side Forge / NeoForge

This mod lets the server send LOD data to players in advance.
After joining a server, players no longer have to slowly explore the world by themselves before Voxy can show distant mountains, builds, terrain outlines, and large landscapes.

It is designed for Forge 1.20.1 and NeoForge 1.21.1 modpack servers, survival servers, building servers, and exploration servers.
If your server already uses Voxy, or if you want to give players a more impressive ultra-distance viewing experience, this version is made for you.

This is a community fork of Voxy Server Side for Forge / NeoForge.
It lets the server prepare LOD data for players, helping Voxy display ultra-long-distance terrain faster and more reliably in multiplayer servers.

Voxy Server Side must be installed on both the client and the server. Voxy itself only needs to be installed on the client.

What It Brings

See LOD Terrain Faster After Joining

Without it, players usually need to explore the map themselves before the client gradually generates LOD terrain.
With it installed, the server can send existing LOD data to players, allowing faraway terrain to appear progressively from the player's position outward.

Better Voxy Experience for Multiplayer Servers

Voxy is great for ultra-long view distances, but on multiplayer servers, each player generating LOD locally can make the experience inconsistent.
This community version lets the server handle LOD sync: once an area has been visited or generated by one player, other players can see it faster later.

This is especially useful for large survival servers, city-building servers, and exploration servers.

Friendlier for Public Servers

The default configuration is tuned to save bandwidth instead of using a large amount of network traffic right away.
Server owners can adjust send speed, LOD range, and generation strength based on their server conditions.

If your server has limited bandwidth, you can start with the default settings and test gradually.

LOD Updates With the World

When players build houses, blow up terrain, or reshape the world far away, the server can notify clients to refresh the related LOD.
This helps prevent distant LOD from staying stuck in an outdated state.

Not Just Terrain: Far Player Display

This feature is experimental. If it causes client crashes due to rendering errors, please disable it.
When far player sync is enabled, ultra-long view distances can show not only terrain, but also players far away.

For large building servers, event servers, and multiplayer exploration servers, this makes the world feel more alive.

Works in Singleplayer and LAN

It is not limited to dedicated servers. Singleplayer worlds and LAN sessions can also use the same logic.

What Server Owners Can Adjust

This version provides /vss commands and configuration files. Server owners can adjust settings based on their server needs:

• How much LOD data each player can receive
• How far the server syncs LOD
• Whether the server is allowed to automatically fill in missing LOD
• LOD refresh speed
• Far player display
• Cache size and read speed

Common command examples:

/vss stats
/vss bandwidth get
/vss bandwidth set_kbps <value>
/vss distance get
/vss distance set <chunks>
/vss generation enable
/vss generation disable
/vss farplayers enable
/vss farplayers disable

Chinese command examples:

/vss 状态
/vss 带宽 查看
/vss 带宽 设置 <Kbps value>
/vss 距离 查看
/vss 距离 设置 <chunk count>
/vss 生成 查看
/vss 生成 开启
/vss 生成 关闭
/vss 生成 状态
/vss 远处玩家 查看
/vss 远处玩家 开启
/vss 远处玩家 关闭

Differences from the original project

This is an unofficial community fork of Voxy Server Side.

The original project is mainly for Fabric / Paper / Purpur.
This fork provides versions for Forge 1.20.1 and NeoForge 1.21.1.

Main differences:

• Added support for Forge 1.20.1 and NeoForge 1.21.1
• Added server-side persistent LOD cache
• Added compressed LOD data transfer
• Added optional far player display / sync
• Improved LOD cache invalidation for changed areas
• Improved request scheduling for Forge / NeoForge servers
• Optimized the default configuration for lower bandwidth and memory usage
• Added Forge / NeoForge modpack compatibility adjustments
• Added singleplayer LOD generation and sync support for Forge / NeoForge
