Illumination modeling

After importing a model using OBJMTLLoader, it is automatically configured as a MeshLambertMaterial, causing the textures to appear darker and not in full color. I am struggling to adjust the lighting in the scene to correct this issue.

I have attempted to add an ambient light, but it has not been sufficient:

scene.add(new THREE.AmbientLight(0xffffff));

Is there a way to disable the 'luminance' setting and make the mesh lambert material visible without relying on any additional lighting in the scene?

Answer №1

If you're looking to update materials, there are a couple of methods you can try. The first involves manually accessing your model file and adjusting the material settings directly within the source code. Alternatively, when using object loader or JSON loader, you can utilize a "for" loop in order to iterate through each material and apply new values accordingly.

var jsonLoader = new THREE.JSONLoader();
jsonLoader.load(model, addCustomMaterialToScene);

                      function addCustomMaterialToScene( geometry, materials ) 
                      {
                          var customMaterial = new THREE.MeshFaceMaterial( materials ); 

                          for ( var i = 0; i < materials.length; i ++ )
                          {
                           var material = materials[i];
                              material.side = THREE.DoubleSide; /// here you have the option to modify attributes
                          }

                          customMesh = new THREE.Mesh( geometry, customMaterial );

                          customMesh.position.set(x,y,z);

                          scene.add( customMesh );
                          console.log(customMesh);
                      }
