        invisibleMaterial.refractionTexture = textureSource;
        invisibleMaterial.refractionTexture.coordinatesMode = BABYLON.Texture.SKYBOX_MODE;
        invisibleMaterial.invertRefractionY = false;
        invisibleMaterial.diffuseColor = new BABYLON.Color3(0, 0, 0);
        invisibleMaterial.specularColor = new BABYLON.Color3(0, 0, 0);
