I have a scene with one mesh with PNG textures. I taken PointLight code from ThreeJS example and added to my project:

 var intensity = 15;
 var pointLight = new THREE.PointLight( color, intensity, 20 );
 pointLight.castShadow = true;
 pointLight.shadow.camera.near = 1;
 pointLight.shadow.camera.far = 60;
 pointLight.shadow.bias = - 0.005; 

But I not see light and shadows on my mesh:

I created a codepen for reproduce this case

How I can resolve this issue?

There were multiple problems with your pen:

• 
  

  You have to tell the renderer to globally enable shadow maps like so:

  
  
  

  renderer.shadowMap.enabled = true
  

  
  


• 
  

  You have to tell the extruded shape to receive shadows:

  
  
  

  mesh.receiveShadow = true;
  

  
  



• The extruded shaped used MeshBasicMaterial in your pen. This is an unlit material which means it does not react on lights. The codepen below now uses MeshPhongMaterial. You might want to consider to add an ambient or hemisphere light so all parts of your mesh are lit.
