title: Can I set the ambient property of a MeshPhongMaterial to false in a three.js imported Blender model?
body: <p>I'm doing a student project and I have a scene with an ambient light and a spotlight. I've imported a Blender model which has the line:</p>
  
  <p>"colorAmbient" : [0.6400000190734865, 0.6400000190734865, 0.6400000190734865], </p>
  
  <p>in the JSON file. </p>
  
  <p>Is there any way to turn off this property in a MeshPhongMaterial so that it only reacts to the spotlight and not the ambient light. </p>
  
  <p>I've tried removing the line and setting it to zero but this has had no effect. Can I turn this property off? Or should I remove the ambient light from a scene and use a different type such as Directional?</p>
  
  <p>Thanks for any help.</p>
