3D Object displaying incorrectly

I am new to 3d game programming and blender. I have followed tutorial 2 to the letter but I'm still having a problem. When I run the tutorial in the simulator my model displays with white triangles. I have converted the face from quad to triangles. What I'm I doing wrong?

Have you put some vertex color? material color? anything?

If not that's probably why, please watch the video tutorials

By adding vertex color it gets rid of the white triangles and gives me a solid color model. However in your tutorial in the beginning part you just add the monkey and export the model and add the sio2 file to your project then it displays as a solid white model. Why is my model displaying white triangles.

Thanks

Cuz there's no material, no vertex color, no texture and the default color is white... what's why
