I fix this solution by this code
anyway, always I have to add camera background screen and render ?

import * as THREE from 'https://cdn.skypack.dev/three@0.129.0/build/three.module.js';
import { GLTFLoader } from 'https://cdn.skypack.dev/three@0.129.0/examples/jsm/loaders/GLTFLoader.js';

const loader = new GLTFLoader();
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera( 25, window.innerWidth / window.innerHeight, 1, 20000 );
camera.position.set( 1, 1, 20 );
var renderer = new THREE.WebGLRenderer({ alpha: false });
renderer.setClearColor( 0xC5C5C3 );
renderer.setPixelRatio( window.devicePixelRatio );
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

loader.load( 'shiba/scene.gltf', function ( gltf ) {
	gltf.scene.scale.set( 1, 1, 1 );			   
	gltf.scene.position.x = 0;				    //Position (x = right+ left-) 
    gltf.scene.position.y = 0;				    //Position (y = up+, down-)
	gltf.scene.position.z = 0;		
	scene.add( gltf.scene );
	
	


}, undefined, function ( error ) {

	console.error( error );

} );

function animate() {
	render();
	requestAnimationFrame( animate );
	}

function render() {
	renderer.render( scene, camera );
	}

render();
animate();
