GLB 纹理不适用于场景形式

Question

我在 android 应用程序中使用 sceneform 1.17.1 并下载 glb 来显示它。我的问题是我有两个 3D 模型，在一个模型中，图像纹理应用得很好。在另一个中，图像纹理不适用。

使用 khronos gltf 验证器，它们看起来很相似。这是工作正常的那个：

                }
            }

    }
}

外观：

这是不加载纹理的那个：

                    "bits": 8
                }
            },
            {
                "pointer": "/images/1",
                "mimeType": "image/png",
                "storage": "buffer-view",

                    "primaries": "srgb",
                    "transfer": "srgb",
                    "bits": 8
                }
            }
        ],
        "animationCount": 0,

        "maxUVs": 1,
        "maxInfluences": 0,
        "maxAttributes": 4
    }
}

这看起来如何：

我在应用程序中没有收到任何错误。如何显示带有纹理的 3D 模型？

Answer 1

问题在于导出 3D 的方式。它被导出为 FBX，然后转换为 GLB。当更改为导出为具有不同比例的 OBJ，然后转换为 GLB 时。效果很好。
