title: Gradient-like color on model imported from blender
body: <p>I imported a model from blender to a C array and displayed it with openGL (glew) under Qt.</p>
  
  <p>I have an embedded resource vertex and fragment shader too. I managed to make the vertex shader work and display correctly the model, but now I'd like to give it a gradient-like effect (it's a simple box, but I'm planning to write on it somehow, so I need to make it look decent).</p>
  
  <p>How may I accomplish this? A texture with blender? Is there any better way?</p>
