I have a simple project with basic terrain created by importing Unity Standard Assets. After that I imported Oculus Integration Asset and Oculus Sample Framework. After importing Oculus Sample Framework and running the scene, I get the errors, Assets/Standard Assets/Characters/FirstPersonCharacter/Scripts/FirstPersonController.cs(3,27): error CS0234: The type or namespace name `CrossPlatformInput' does not exist in the namespace `UnityStandardAssets'. Are you missing an assembly reference? Assets/Standard Assets/Characters/FirstPersonCharacter/Scripts/FirstPersonController.cs(24,34): error CS0246: The type or namespace name `CurveControlledBob' could not be found. Are you missing `UnitySampleAssets.Utility' using directive? Similarly, the same error appears for many other files in Standard Assets. I could also see that CrossPlatformInput exists in Assets/Standard Assets/CrossPlatformInput, Assets/Standard Assets/Editor/CrossPlatformInput etc. Need help in solving this.
