Hello,
There is some warning consoles on the latest version of Edge and Internet Explorer.
They are visible on this page : https://www.babylonjs.com/demos/pbr/
They are related to these lines :
element.addEventListener("keydown", this._onKeyDown, false);
element.addEventListener("keyup", this._onKeyUp, false);
I didn't find any problem with this except the console message but that would clear my console :p.
