How to modify the launch window with own 3D animation?
In Hololens, as default, there will be a Window pop-up (then it will ask you to tap it on the wall) when you select an app. I try to find a way to customize it with my own 3D model or animation, just like what been seen in those demo apps. Is there anyway to achieve? Thanks in advance for any suggestions.
