TerramizerServer

TerramizerServer is a dedicated-server performance companion for Terramizer. It improves world-state delivery and server-side object coverage for split-up players without requiring a client mod.

Compatibility

Works with Terramizer 0.8.2, vanilla clients, or a mixture of both.
Uses no custom network protocol, handshake, or synchronized client configuration.
Terramizer remains optional and client-side; TerramizerServer remains dedicated-server-only.
Built against Valheim 0.221.12, Unity 6000.0.61f1, and BepInEx 5.4.23.3.

What it does

Combines active object coverage for every ready peer.
Predicts movement so server-side loading can prepare in the direction of travel.
Prioritizes player, terrain, solid, explicitly prioritized, and nearby ZDO state.
Applies socket backpressure and dense-area pauses to proactive zone-entry boosts.
Deduplicates outgoing sync lists.
Repairs narrowly validated stale ownership routes for removable build pieces and nearby item drops.
Tunes sleep fast-forward while preserving the normal world-save policy by default.
Skips unnecessary visual and audio initialization in headless mode.
Reports synchronization, queue, streaming, ownership-repair, and stale-instance diagnostics.

Version 0.5.0 cleanup

Retired full peer-zone instantiation and mass persistent-ZDO ownership code has been removed, along with its obsolete settings and patches. Existing configs automatically drop those retired entries. The still-active coordination interval is now named StreamingUpdateIntervalSeconds under the Streaming section.

Installation

Install this package on the Valheim dedicated server only. The package places the DLL at:

BepInEx/plugins/TerramizerServer/TerramizerServer.dll

The generated config is:

BepInEx/config/r4v9n1.terramizerserver.cfg

Keep SkipSleepWorldSave = false unless you knowingly accept reduced save durability. Change one setting at a time and retain the BepInEx log when reporting performance or multiplayer interaction problems.
