我为 Blender 找到了这个不错的汽车座椅,然后将整个场景导出为 GTLF2.0,并通过 Qt Design Studio 作为 QML Asset 导入。

我遇到了一些时间轴问题,我手动修复了这个问题,但是如图所示,一个材质看起来有问题。

问题1

我使用 GLTF Onlineviewer链接检查了相同的 GLTF2.0 文件,看起来与 Blender 相同。

好的

之后我检查了其他 GLTF Onlineviewer Link,在这里我遇到了同样的问题。

问题2

问题:

  • 有人知道或提示我哪个值可能是麻烦制造者吗?
  • 是不是雷电问题?

问题出在纹理映射属性下的 PrincipledMaterial 中

U 刻度 = 1 V 刻度 = 1

我将两者都更改为0,但没有任何改变。我不得不再次在 3D 编辑器中重新加载场景。

好的

色差不是问题。我必须适应一点光线等。

这里是更正后的 PrincipledMaterial 的提取。

PrincipledMaterial {
