Promote a single runtime-spawned proxy as the preferred active remote-player representation (Stage 3 / 3.7) while preserving the placed reference as a fallback. Updates include: detailed architecture and dev-log additions describing staged diagnostics (3.1–3.7), PlaceAtMe-backed spawn candidate isolation/settle, vanilla/Codsworth diagnostics, console PlaceAtMe testing, near-player visibility holds, and PASS/PARTIAL/FAIL diagnostic outcomes. Code changes (plugin/include & plugin/src): adjust header comment and implement numerous runtime proxy features and diagnostics: new constants, enums, structs, state variables, logging helpers, position/distance helpers, absolute FormID lookup, runtime actor base selection (custom vs vanilla), PlaceAtMe-backed spawn state machine, debug placement/hold timing, candidate snapshot/isolation, promotion to active runtime proxy, and many throttled/logged diagnostics. The placed CK reference remains the fallback if runtime spawn/validation fails. Docs changed: docs/architecture.md and docs/dev-log.md updated to describe the new Stage 3 behavior and testing notes. Files changed: docs/architecture.md, docs/dev-log.md, plugin/include/F4TProxyActorController.h, plugin/src/F4TProxyActorController.cpp. Behavioral notes: single-proxy only (Stage 4 mapping deferred), extensive diagnostic logging added, and in-game validation/testing remains pending.
Fallout 4 Together
Fallout 4 Together is an experimental research project exploring the possibility of adding basic multiplayer-style networking to Fallout 4.
The goal is not to create a full co-op campaign mod immediately. The first goal is much smaller:
Two Fallout 4 clients in a controlled test environment, with each player visible as a synced remote actor.
This project is currently in the research and prototype stage.
Project Goals
First Prototype
- Load a native Fallout 4 plugin through F4SE
- Connect to a local test server
- Send local player position data
- Receive remote player transform data
- Represent another connected player using a placeholder actor
- Restrict all testing to a custom test cell
Long-Term Ideas
- Basic LAN multiplayer test mode
- Remote player movement sync
- Basic animation state sync
- Basic chat or debug messages
- Host-controlled test cell
- Simple co-op combat arena
Non-Goals
This project is not currently trying to support:
- Full Fallout 4 campaign co-op
- Quest synchronization
- Settlement synchronization
- Full NPC/world state synchronization
- VATS synchronization
- Public server/MMO gameplay
- Compatibility with large modlists
Those systems are extremely complex and are outside the scope of the first prototype.

Requirements
This project is expected to require:
- Fallout 4 on PC
- Fallout 4 Script Extender, F4SE
- Fallout 4 Creation Kit
- Visual Studio 2022 or newer
- CMake or another supported C++ build system
- A CommonLibF4-based plugin template
- Git
- A clean Fallout 4 test profile
Recommended Development Setup
Use a separate Fallout 4 installation or a dedicated modding profile for testing.
Recommended setup:
Fallout 4
F4SE
Creation Kit
Mod Organizer 2 or Vortex
Visual Studio
Git
Use a clean test save and avoid testing with a full personal modlist.
