Question

我一直在尝试加载 GLB 文件，但是即使PNG文件位于相同的 assets 文件夹中，它的纹理也似乎无法加载。

代码如下：

val GLTF_ASSET = "model.glb"

ModelRenderable.builder()
            .setSource(
                this, RenderableSource.builder().setSource(
                    this,
                    Uri.parse(GLTF_ASSET),
                    RenderableSource.SourceType.GLB
                )
                    .setScale(0.5f)
                    .setRecenterMode(RenderableSource.RecenterMode.ROOT)
                    .build()
            )
            .setRegistryId(GLTF_ASSET)
            .build()
            .thenAccept {
                loadModel(it)
            }
            .exceptionally {
                val builder = AlertDialog.Builder(this)
                builder.setMessage(it.message)
                    .setTitle("error!")
                val dialog = builder.create()
                dialog.show()
                return@exceptionally null
            }

我在日志中收到此消息：

Answer 1

这通常意味着您在GLTF文件中声明了资源纹理，并且使用该纹理的路径无效。

确认您的GLTF文件已正确打包并包含纹理。

在我看来，您就像在对待SFB文件或DAE文件一样，在图像文件中分别具有纹理。让您的设计师将它们导出为打包的纹理，您应该会很好。

使用Sceneform（ARCore）加载GLB文件及其纹理
