I based on the instruction on Youtube (LivePreview with UNITY (LeiaRemote): The Lume Pad as a 3D display second screen. - YouTube) to install UNITY SDK in lume Pad as a second screen.
When I press PLAY button, lume pad can show the same object, for example, a cube as unity in my PC.
But the problem is the cube in lume pad is still 2D not 3D. Are there some parameters I need to set? So I can show 3D object in lume pad when I generate object in my PC. Like this page Leia Remote - Developer Docs
Thanks so much,
