Create a new project in Unity 2018.1.0b7
Import Cinemachine 2.1.11-beta.1 through the Package Manager
Try to build empty scene
Currently you can not build any project with cinemachine 2.1.11-beta (imported through the package manager) as unity trys to compile the editor scripts into the build too.
@Gregoryl@Adam_Myhill I’m using RC2 and I can’t find CinemachinePostProcessing extension, Is that a bug? (I’m using PostProcessing from Package Manager)
Update: Upgrading to RC3.
Update 2: Still not here.
