Unity VR Overlay
Very simple fade-to-black (and back) overlay system for Virtual Reality applications (Oculus DK2 tested) in Unity 5. Useful as a graceful transition for intial environment loading and level switching.
Compatibility
References a Shader from the Oculus VR SDK: "Oculus/Unlit Transparent Color" found in the OVR/Moonlight/Resources folder.
Usage
Drag the LoadingOverlay prefab to your main camera.
Fade in the scene with:
LoadingOverlay overlay = GameObject.Find("LoadingOverlay").gameObject.GetComponent<LoadingOverlay>();
overlay.FadeIn();
Fade out with:
overlay.FadeOut();
