how to deal with "emission.jpg" and "normal.jpg" using trimesh

[ydove0324]

the code looks like this

    albedo_image = Image.open(f"{path}/albedo.jpg")
    emission_image = Image.open(f"{path}/emission.jpg")
    normal_image = Image.open(f"{path}/normal.jpg")

    # 创建 mesh 对象
    mesh = trimesh.Trimesh()

    # 提取顶点坐标并转换为 NumPy 数组
    vertices = np.array([list(vertex_coords.values()) for vertex_coords in data["vertices"]], dtype=np.float64)
    mesh.vertices = vertices

    # 提取法线并转换为 NumPy 数组
    normals = np.array([list(normal.values()) for normal in data["normals"]], dtype=np.float64)
    mesh.vertex_normals = normals

    # 提取三角形索引
    triangles = np.array(data["triangles"], dtype=np.int32).reshape(-1, 3)
    mesh.faces = triangles

    # 填充纹理坐标信息
    uvs = np.array([list(uv.values()) for uv in data["uvs"]], dtype=np.float64)
    
    # 创建纹理和材质
    albedo_material = trimesh.visual.texture.SimpleMaterial(image=albedo_image)
    emission_material = trimesh.visual.texture.SimpleMaterial(image=emission_image)
    normal_material = trimesh.visual.texture.SimpleMaterial(image=normal_image)
    
    # 应用纹理
    material = trimesh.visual.material.TextureMaterial(
        diffuse=albedo_image, 
        emissive=emission_image, 
        normal_map=normal_image
    )

although it's a wrong code. But I want to load emission and normal into the mesh
