gltf 文件在框架中呈现不正确

Question

谁能帮我调试 glTF 文件？在 https://gltf-viewer.donmccurdy.com/ (though it's pretty different from how it looks in Blender) but most of its pieces are missing when I use aframe to look at it: https://sgouros.com/scorpii/index1.html. The model is at https://sgouros.com/scorpii/data/scorpii3.glb

的 Don McCurdy 的 glTF 查看器中看起来不错

发生这种情况是因为模型的透明节点 in most cases should have 禁止通过其 material 写入深度缓冲区。

引用 Khronos wiki（或引用 Don McCurdy 引用维基）：

The standard method for dealing with translucent objects ... involves disabling writes to the depth buffer and sorting transparent objects and/or polygons based on distance to the camera.

因此您可以只遍历网格并对透明对象禁用 depthWrite：

model.traverse(node => {
    if (node.isMesh) {
           node.material.depthWrite = !node.material.transparent;
    }
});

就像我在 this glitch 中使用提供的模型所做的那样。
