RepGraphPro

RepGraphPro makes Unreal's high-performance Replication Graph accessible. Route replication by team, attach dependent actors and use spatial grids - configured from Blueprints, scaled for big player counts.

RepGraphPro replaces Unreal's brute-force relevancy checks with a Replication Graph you configure instead of code: assign connections to teams, declare dependent actors that replicate with their owner, and let spatial grid nodes cull by location. Class replication policies come from presets, so tuning replication behavior is data work rather than C++ surgery, and a runtime check node tells you the graph is active.

It is built for ambitious multiplayer: battle-royale and large-arena shooters, MMO-lite worlds, persistent social spaces - any project where hundreds of replicated actors per connection would melt a naive setup. You get engine-grade scalability with Blueprint-level accessibility.

RepGraphPro is part of the Alpha XP networking collection for Unreal Engine 4.27-5.0+. Every feature is exposed to both Blueprints and C++, ships with styled HTML documentation, and follows one consistent API style across the whole collection. The plugin is compiled and verified against a clean UE 4.27 project, comes with a utility node pack (hashing, GUIDs, timestamps, tokens, validation), and is maintained under the Alpha XP brand with documentation hosted online.

Key Features:

- Replication Graph implementation, Blueprint-configurable

- Team-based connection routing

- Dependent-actor replication

- Spatial grid nodes for open worlds

- Runtime IsRepGraphProActive checks

- Utility node pack: CRC32/MD5/SHA-1 hashing, GUIDs, timestamps, random tokens and hostname validation
