Cinemachine is great, and the free look camera seems to work pretty much out of the box with mobile touch. However, I’m struggling to work out how to stop the free look cinemachine camera reacting to click events on buttons placed on a UI canvas.
So the GUI layer in Unity does not by default hide the mouse events from the input manager. If the input manager is reading the mouse and feeding it to the FreeLook, this will happen whether the mouse is on a GUI button or not.
