Hello,
There is a bug in the PluginLeapNotice prefab in the CoreAssets of Orion (version 4.1.1 is the one I'm using). This is the error message that pops in the console:
NullReferenceException: Object reference not set to an instance of an object
Leap.Unity.DisconnectionNotice.SetAlpha (Single alpha) (at Assets/LeapMotion/Scripts/Utils/DisconnectionNotice.cs:42)
Leap.Unity.DisconnectionNotice.Update () (at Assets/LeapMotion/Scripts/Utils/DisconnectionNotice.cs:74)
I inquired into the code to see if it was a cmisconfigration from me, but I found at that line:
GetComponent<UnityEngine.UI.Image>().color
which causes this exception as the prefab doesn't have an Image component, it has a GUITexture.
