Obj Material

[wen]

Hi, I am new to Babylon JS. I have successfully imported the obj file but how do I add texture to it? I tried the following codes but to no avail:

 

 var material = new BABYLON.StandardMaterial("goldMaterial", this.scene);
    material.diffuseTexture = new BABYLON.Texture("textures/gold.jpeg", this.scene);
    material.specularColor = BABYLON.Color3.Black();
    material.emissiveColor = BABYLON.Color3.White();

 BABYLON.SceneLoader.ImportMesh(null, "models/", "majahapitGold.obj", this.scene, (meshes) => {
      
      var room = meshes[0];
      room.scaling = 0.001;
      room.position = new BABYLON.Vector3.Zero(0, 5,0)
      room.material = material;
      this.camera.radius = 3000;

});
