You can use script code to determine at runtime whether the headset is immersive or holographic by checking displayOpaque on the actively running XRDisplaySubsystem. To check the camera's opaqueness, the MixedRealit圜amera system has an IsOpaque property. MRTK will handle specific camera settings automatically, based on the configuration in the camera system profile. If setting this from code, you can use Unity's Color.clear.Select the Background color picker and change the RGBA values to (0, 0, 0, 0).In the Inspector panel, find the Camera component and change the Clear Flags dropdown from Skybox to Solid Color.Select the Main Camera in the Hierarchy panel.Set the camera background to be transparent (in HoloLens, black renders as transparent) instead of a Skybox texture: However, when running on a holographic headset like HoloLens, the real world should appear behind everything the camera renders.When running on an immersive headset, you're rendering everything the user sees, and so you'll likely want to keep the skybox.The default settings on the Unity Camera component are for traditional 3D applications, which need a skybox-like background as they don't have a real world. However, to fully optimize visual quality and hologram stability, you should set the camera settings described below. The Unity Camera component will automatically handle stereoscopic rendering and follow your head movement and rotation. When you wear a mixed reality headset, it becomes the center of your holographic world.
