Control OBS Studio directly from Unreal Engine. No external scripts, no middleware.

Inhyeong OBS WebSocket is a full OBS Studio WebSocket v5 client for Unreal Engine 5.5+. Drive scenes, recording, streaming, audio, filters, and more from Blueprint, C++, the Sequencer timeline, or gameplay triggers. Everything works at runtime or right inside the editor without entering Play mode.

This plugin controls a running OBS instance over the network. It does not capture, encode, or restream your video.

Built for streamers, VTubers, and virtual production:

• Mic and voice-activity detection. Talking switches to animated, idle returns to resting, entirely in-engine.

• Sequencer integration. Frame-accurate, timeline-driven OBS control with keyframeable volume, transforms, filters, and media cursor.

• No-code Trigger Volumes. Automate scene switches, replays, and audio when players enter areas, gated by audio or source-visibility conditions.

• Take Recorder sync. OBS recording follows your takes, with chapter markers. Requires the built-in Takes plugin.

• Outbound game events. Push structured events from your game to OBS overlays and plugins.

Full OBS coverage: scenes and scene items, recording (split and chapters), streaming, virtual camera, replay buffer, studio mode, transitions, source filters, screenshots, audio (volume, mute, balance, monitoring, tracks), input and source management, media playback, profiles, scene collections, video settings, and persistent data.

Developer-friendly:

• 100+ Blueprint-callable functions and 60+ events, each with a native C++ delegate counterpart

• Rich editor details panels with live status indicators

• Auto-reconnect with exponential backoff

• Efficient request batching
