For some reason, I can no longer rotate the viewport in any of my projects. I can move the viewport around, and zoom in/out, and switch from iso to perspective, but I cannot rotate the viewport. Very annoying.
I’m getting an error message every time I move my cursor over the viewport, as well:
transform.rotation assign attempt for 'SceneCamera' is not valid. Input rotation is { NaN, NaN, NaN, NaN }.
UnityEditor.DockArea:OnGUI()
Anybody know what might be going on? I recently upgraded to Pro, could that be affecting it?
