嘿，伙计们，我是three.js的新手，我正在尝试使用Meshmatcap材质更改我的纹理。然而，我面临的问题是，我更改了纹理，添加skinning: true后，我的模型纹理和颜色将消失，这是我的模型保持大小所必需的。有什么办法解决这个问题吗？提前谢谢。当前使用的模型来自https://sketchfab.com/3d-models/tyrannosaurus-rex-9d3a3e42c0054c35aa39c3ee07388d16

用手动加载的纹理替换glTF资源的纹理时，必须将Texture.flipY属性设置为false，以适应glTF的uv约定。
THREE.GLTFLoader的文档页面中也提到了这种情况。
