【中文标题】三.js gltf模型变灰无纹理，改纹理后【英文标题】：three.js gltf model becomes grey and textureless, after changing texture 【发布时间】：2022-01-19 08:30:44 【问题描述】：大家好，我是 three.js 的新手，我正在尝试使用 Meshmatcap 材料更改我的纹理。但是，我遇到了一个问题，我更改了纹理，我的模型纹理和颜色在添加 skinning: true 后会消失，这是我的模型保持尺寸所必需的。有没有办法解决这个问题？提前致谢。目前使用的模型来自https://sketchfab.com/3d-models/tyrannosaurus-rex-9d3a3e42c0054c35aa39c3ee07388d16

【问题讨论】：
【参考方案1】：当使用手动加载的纹理替换 glTF 资产的纹理时，您必须将 Texture.flipY 属性设置为 false 以适应 glTF 的 uv 约定。
THREE.GLTFLoader的documentation page也提到了这种情况。

它现在可以工作了，谢谢伙伴以上是关于三.js gltf模型变灰无纹理，改纹理后的主要内容，如果未能解决你的问题，请参考以下文章
