How to Use FBX Models with three.js

I'm studying computer graphics with WebGL and want to utilize Three.js to draw FBX models. I have succeeded in loading the FBX models that are shared for free, but I don't know how to add textures and other details. In the downloaded file, there is one fbx file and several png files in a folder called maps, and I was wondering how to use them.

import * as THREE from '../three/build/three.module.js'; import { FBXLoader } from '../three/examples/jsm/loaders/FBXLoader.js'; import { OrbitControls } from '../three/examples/jsm/controls/OrbitControls.js'; window.onload = function init() { const canvas = document.getElementById("gl-canvas"); canvas.width = window.innerWidth; canvas.height = window.innerHeight; const renderer = new THREE.WebGLRenderer({ canvas }); renderer.setSize(canvas.width, canvas.height); const scene = new THREE.Scene(); scene.background = new THREE.Color(0xffffff); const camera = new THREE.PerspectiveCamera(75, canvas.width / canvas.height, 0.1, 1000); const contorls = new OrbitControls(camera, renderer.domElement); const light = new THREE.DirectionalLight(0xffffff, 1); light.position.set(1, 1, 1).normalize(); scene.add(light); camera.position.z = 5; camera.position.y = 5; camera.rotation.x = THREE.MathUtils.degToRad(-30); const loader = new FBXLoader(); loader.load('../assets/Hoonicorn.fbx', function (object) { scene.add(object); object.scale.set(0.1, 0.1, 0.1); if (object.animations && object.animations.length > 0) { const mixer = new THREE.AnimationMixer(object); const action = mixer.clipAction(object.animations[0]); action.play(); const clock = new THREE.Clock(); function animate() { requestAnimationFrame(animate); const delta = clock.getDelta(); mixer.update(delta); renderer.render(scene, camera); } animate(); } else { function animate() { requestAnimationFrame(animate); renderer.render(scene, camera); } animate(); } }); } 

This is the FBX model once I loaded it. When I actually downloaded it, the image was cosmetically decorated.

I was wondering if there is a way to verify that the additional downloaded FBX models are animating separately.

I tried using blender to open the fbx file, but I don't know how to use blender. I'm a complete beginner.
