Hey folks,   I am using a FreeCamera and want to be able to rotate all the way around the x-axis but the rotation always stops when I look straight down. I searched the forum and the web but I couldn't find a setting to disable that. Is that a technical limitation or is it somehow possible to create a workaround?   Not sure how useful a playground for that question is, but better to have on than not to  http://www.babylonjs-playground.com/#22PVJH   You start looking at a sphere, then look down,
