title: Reflection between objects ( three.js & gltf2 )
body: <p>Good evening. I am export two models from Blender 2.79 to three.js.</p>
  
  <p>Scene: <a href="https://www.blend3dweb.ru/projects/test_reflection.html" rel="nofollow noreferrer">link</a></p>
  
  <p>Shadows work. Objects reflect the world around them but do not reflect among themselves.</p>
  
  <p>Scene code:</p>
  
  <pre><code>        function init() {
              camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 1, 1000 );
              camera.position.set( 0, -8, 2 );
                              // envmap
              var path = '/textures/sky_glTF/pisa/'; // ADD "/"
              var format = '.png';
              var envMap = new THREE.CubeTextureLoader().load( [
                  path + 'px' + format, path + 'nx' + format,
                  path + 'py' + format, path + 'ny' + format,
                  path + 'pz' + format, path + 'nz' + format
              ] );
              scene = new THREE.Scene();
              scene.background = envMap;
  
  
  
                           //MR -  YES mirror
              var loader = new THREE.GLTFLoader();
              loader.load( '/gltf/1.gltf', function ( gltf ) {
  
                  gltf.scene.traverse( function ( node ) {
  
                      if ( node.isMesh || node.isLight ) node.castShadow = true;
                      if ( node.isMesh || node.isLight ) node.receiveShadow = true;
  
                  } );
  
                         gltf.scene.traverse( function ( child ) {
  
                      if ( child.isMesh ) {
  
                          child.material.envMap = envMap;
                      }
  
                  } );
                  gltf.scene.position.x = 0;
                  gltf.scene.position.y = 0;
                  gltf.scene.position.z = 0;
  
                         scene.add( gltf.scene );
  
              } );
                           //MR -  YES mirror
              var loader = new THREE.GLTFLoader();
              loader.load( '/gltf/2.gltf', function ( gltf2 ) {
  
                  gltf2.scene.traverse( function ( node ) {
  
                      if ( node.isMesh || node.isLight ) node.castShadow = true;
                      if ( node.isMesh || node.isLight ) node.receiveShadow = true;
  
                  } );
  
                  gltf2.scene.traverse( function ( child ) {
  
                      if ( child.isMesh ) {
  
                          child.material.envMap = envMap;
  
                      }
  
                  } );
                      gltf2.scene.position.x = 0;
                      gltf2.scene.position.y = 0;
                      gltf2.scene.position.z = 0;
  
                      scene.add( gltf2.scene );
  
              } );

  <p>How to implement reflections between objects?</p>
  
  <p>What part of the code do you still have to show for a complete answer to my question?</p>
