I have a Samsung Galaxy Note 3 (I think this is almost identical to Galaxy S4) and I am able to build the sample content (except Strategy game) with no problems on my Android phone.
However, I have tried to create two different custom basic levels and the result is a black/very dark grey result on my phone. It’s as if the lighting is not rendering correctly.
On the most basic level I have one static light. In the editor it seems that perhaps something is not right as when building the lighting is complete the scene looks correct (with static shadows etc) but as soon as you move the camera or click any button in the editor, the shadows disappear and a more broad lighting result is displayed.
Has anyone else had this problem?
