CreateScene(scene: Scene, canvas: HTMLCanvasElement) {
this.light = new HemisphericLight(“light”, new Vector3(0, 1, 0), this.scene);
this.light.parent = this.camera;

const envTexture = CubeTexture.CreateFromPrefilteredData("./assets/environment/environmentSpecular.env", scene);
scene.environmentTexture = envTexture;

var blur = 0.8;
scene.createDefaultSkybox(envTexture, true, 10000, blur);

scene.clearCachedVertexData();
scene.cleanCachedTextureBuffer();
scene.createDefaultCamera();

DracoCompression.Configuration = {
    decoder: {
        wasmUrl: './assets/js/draco_wasm_wrapper_gltf.js',
        wasmBinaryUrl: './assets/js/draco_decoder_gltf.wasm',
        fallbackUrl: './assets/js/draco_decoder_gltf.js',
    }
};


this.meshUrl = this.productDetail.productCode + ".glb";
this.modalPath = environment[global.env].RESOURCE_URL_AMAZON + environment[global.env].RESOURCE_CONTAINER + environment[global.env].oemCode + "/preview/" + this.productDetail.productCode + '.glb';

Tools.LoadFile("./assets/models/" + this.meshUrl, async (data: any) => {
    try {
        var dracoCompression = new DracoCompression();

        var attributes = {
            [VertexBuffer.PositionKind]: 3
        };

        var vertexData = await dracoCompression.decodeMeshAsync(data, attributes);
        var mesh = new Mesh("dracoMesh", scene);
        var geometry = new Geometry("dracoGeometry", scene, vertexData, undefined, mesh);

        mesh.material = new PBRMaterial("material", scene);
        mesh.material.sideOrientation = Material.CounterClockWiseSideOrientation;

        scene.createDefaultCameraOrLight(true, undefined, true);
    } catch (error) {
        console.error("Error loading 3D model:", error);
    }
}, undefined, undefined, true);

return scene;

} that is my code

Can you reproduce your issue in the Babylon.js playground ?

It sounds really hard to troubleshoot from your code only.

Does http://localhost:4200/assets/js/draco_wasm_wrapper_gltf.js exist? You can also try disabling workers (DracoCompression.DefaultNumWorkers = 0 or var dracoCompression = new DracoCompression(0)) and see if that resolves the problem to see if it’s worker related.

Do you use this code in nodejs？If so, please refer to the following code
