⚙️ Key Features

🔊 Update 1.1 - Effects & Receiver

• Turn any object into a radio, intercom, walkie-talkie or loudspeaker

• Listens on one channel and rebroadcasts every speaker on it, from its location, with its own attenuation, occlusion and effects

• Speakers still emit from their own body too: someone next to the speaker hears them directly, someone next to the radio hears them through it

• Per-receiver settings: output config, volume, attach socket, priority, max simultaneous speakers

• Run the voice itself through a Source Effect Chain, bitcrusher, EQ, ring mod, anything.

• Set it per config asset, applied per emitter

• Swappable at runtime, picked up on the next talk burst

🔊 Proximity Voice

• Spatialized 3D playback with distance attenuation

• Opus encoding with a built-in jitter buffer for smooth audio over the network

• Works on listen servers and dedicated servers, fully testable in PIE

🧱 Occlusion Through Geometry

• Voices get muffled by walls between speaker and listener

• Per physical material presets, glass, wood, concrete each sound different

• Volume attenuation and low-pass filtering stack realistically per surface

📻 Channels

• Speakers talk and listen on a channel, listeners only hear their own channel

• Perfect for squads, radios, lobbies and spectators

• One Blueprint node to switch

🔇 Muting

• Local mute, silence one player for yourself only

• Server mute, block a player, or the entire session, from authority

• Fully replicated and authority-safe

🎛️ Runtime Configuration

• Every tunable lives in a ProximityVoiceConfig Data Asset, nothing is hardcoded

• Swap presets at runtime: enter a cave, change the rules

• Tune ranges, latency, occlusion and capture in the details panel

🔌 Steam & EOS Ready

• Runs entirely over your game's normal replication

• Works with Steam and EOS out of the box, zero extra setup

• No OnlineSubsystem voice, no EOS RTC product to provision

🧩 Blueprint API & Debug

• 26 Blueprint nodes (20 functions, 6 events)

• Activity, channel, mute and self-voice events to drive your UI

• In-world debug overlay: ranges, occlusion traces, live voice levels

💡 Why This Plugin?

Voice chat is usually the last thing you add and the first thing that breaks. Most solutions drag in an online backend, force you out of PIE, and treat voice as plumbing. EPVC treats voice as a gameplay signal, something you can occlude, channel, mute and reconfigure like any other system.

• ✅ Drop-in: one component, one setting

• ✅ Blueprint-first API, no C++ required

• ✅ Fully networked, dedicated-server ready

• ✅ Testable in PIE, no backend to boot
