This is a ray-tracing compatible virtual camera that offers the simplest workflow for live-streaming from inside Unreal.


It outputs to any SPOUT receiver program, including OBS (for easy live-streaming to the internet) via our SPOUT-OBS plugin:


Technical Innovation:

  • Converts DX12 (ray-traced) textures to DX11 and outputs as a real-time video feed.
  • Real-time video feed has almost zero-latency (better than NDI).
  • Can output multiple, simultaneous real-time video streams from a single level with resolutions up to 4K.


Ease-of-Use:

  • Is plug-and-play: Drop the camera into your scene and it streams video output immediately.
  • Can be attached to actors/ used with the sequencer/ controlled with blueprints.
  • It doesn't block your viewport while you stream (better than a capture card).


Cross-Compatibility

  • Can output real-time video to any SPOUT receiver (TouchDesigner, Resolume, Notch etc.)
  • Can live-stream video direct from Unreal in combination with our SPOUT to OBS Studio plugin
  • Can be used in Editor view or packaged into an executable.
