I dont see any debug files only a logfile.txt. I read, that the deferred render for android opengles 2 is too slow. My tablet with mali gpu only supports opengl es 2 and the zombie game dead trigger runs smoothly with some cool shaders, but anyway. Yeah, having 2 render backend might be useful. Some place said, that the Unreal engine uses forward render to render the transparency. I found this -> http://sourceforge.net/projects/isdge/ the render looks like neo to me.
