Can not draw 3d scene on mobiles

Hi, I just updated the latest engine code, run the 04_StaticScene sample on my iPad and nexus 4, but 3d scene not drawn, just ui showed.
anybody help?

I think you need to be more specific than this.

Just updated the master code again, and found some glsl bug fixed, now, everything is ok. :smiley:
Thank you very much.
