4. Enabling the Mixed Reality Capture Framework Plugin
Integrating the Mixed Reality Capture (MRC) framework into your project is as easy as enabling the Mixed Reality Capture framework plugin. With the MRC plugin enabled and the calibration settings file in place, the game should start in MRC mode and display the composited scene to the spectator window.
By default, MRC broadcasting uses the VR Spectator Screen
to display the composited scene. If the game isn’t in VR mode, then the Mixed Reality capture will not be displayed. The MRC plugin is capturing, it's just not displaying.
Mixed Reality captures are supported both in the editor (VR PIE) and in packaged projects, as long as the MRC plugin is enabled.
Starting in MRC Mode
When the MRC plugin starts up, it checks for a calibration settings file (MrcCalibration.sav) in the game's /Saved/SaveGames/ folder. If the MRC plugin does not find a calibration settings file, it will not start in MRC mode. Below is a diagram showing how the game determines whether to start in MRC mode or not.
