ScarCore is a production-ready, Blueprint-only communication framework that adds server-authoritative text chat, voice chat with push-to-talk, teammate pings, and a per-player mute roster to your game with zero C++ and absolutely no input mapping configuration.

If you have ever tried to build multiplayer voice from scratch, you already know that Unreal Engine's native voice replication is a grueling 2-to-3 week rabbit hole of registration timing errors, silent late-joiners, session resets, and broken dedicated servers. ScarCore completely eliminates this headache. You simply add one component to your PlayerController and press Play.

Why Developers Choose ScarCore:

• Flawless Dedicated Server Voice (Opus Relay): Bypasses legacy session-based limitations to route compressed audio directly over your active game connection. Voice chat finally works out-of-the-box on direct-IP and headless dedicated servers without needing an active online subsystem session.

• Proximity Spatial Attenuation: Automatically attaches VOIP talkers to character pawns, stopping embarrassing bugs where players hear each other globally across the map.

• Server-Authoritative Security: Chat sender names are validated strictly on the server from PlayerState to prevent client-side name spoofing, backed by server-side profanity filtering and rate limiting.

• Complete Pre-Built UI: Includes a beautiful, customizable, collapsible HUD containing active text logs, quick-message panels, individual volume sliders, per-player mute lists, and live ping indicators.

• 1-Click Platform Configuration: Automatically writes proper engine configuration blocks for Steam, Epic Online Services (EOS), or LAN (Null) directly to your DefaultEngine.ini.

Technical Specifications:

• Engine Compatibility: Unreal Engine 4.27 and 5.0 through 5.7.

• Subsystems Supported: Steam, Epic Online Services (EOS), LAN (Null), Dedicated Servers.

• Mobile Permissions: Ready-to-go Android and iOS mic/network permission setups included.

Stop fighting replication bugs. Stop wasting weeks of development time on boilerplate networking code. Get ScarCore today and focus entirely on making your game fun.
