Question

我最近刚刚开始为我正在创建的网站创建一个3D模型..由于某种原因，角色的一个部分是透明的，但只有部分就像你在里面看到的那样。如下所示： Transparent arm我无法弄明白。我试着追回我的一些代码无济于事，我尝试在blender中渲染它（因为它是.obj导入），它仍然有同样的问题。有没有人碰巧知道这个问题的解决办法？

我此时有点失落，可以真正使用你的帮助！提前致谢。如果您有任何疑问，或者对我的代码中的某些内容不确定，请告诉我。

手臂的脸部法线可能会翻转到背面。您可能知道，如果面法线面向背面，则不会渲染，只会渲染背面，即使在3d建模器中也是如此，例如搅拌器。

您也可以使用FaceNormalsHelper检查three.js中的正常方向。

帮助者的文件：

如果法线方向错误，请在3d建模应用中翻转它们。
