Title: Unreal VCam on UE 5.6 for macOS Ignores Network Endpoint Configuration

  • Engine Version: 5.6 (Pre-release)

  • Platform: macOS 15.5 on Apple Silicon (M4 Pro)

  • Description: The Unreal VCam v2 plugin fails to bind to the specified network IP address, preventing any network connection from an iOS device. The integrated Pixel Streaming server consistently defaults to 127.0.0.1.

  • Steps to Reproduce:

    1. Create a new, empty project on macOS with an M4 Pro.

    2. Enable the Virtual Camera plugin and restart.

    3. Add a VCamActor to the scene.

    4. Attempt to set the network endpoint using any standard method.

    5. Activate the VCam and observe the Output Log.

  • Troubleshooting Performed:

    • Setting PixelStreaming.Streamer.Endpoint via DefaultEngine.ini is ignored.

    • Setting PixelStreaming.Streamer.Endpoint via a Python Startup Script fails with a Could not load Python file error, indicating a bug in the script loader.

    • Setting PixelStreaming.Streamer.Endpoint via a manual console command (Cmd) immediately before activation is also ignored, with the VCam server still starting on 127.0.0.1.

  • Conclusion: The VCam activation logic overrides all external configuration for the network endpoint, making it unusable over a network on this platform.
