QtQuick3D/Qt Design Studio GLTF 导入 Material 看起来不对

Question

我发现 this 适合 Blender 的漂亮汽车座椅，然后将整个场景导出为 GTLF2.0，并通过 Qt Design Studio 导入为 QML 资产。

我遇到了一些时间线问题，我手动修复了这个问题，但是 Material 看起来不对，如图所示。

我用 GLTF Onlineviewer 检查了相同的 GLTF2.0 文件 Link，看起来与 Blender 相同。

后来我用其他 GLTF Onlineviewer 检查 Link 在这里我有同样的问题。

问题：

有人知道或给我提示哪个值可能是问题所在制造商？
不会是雷电问题吧？

Answer 1

问题出在纹理映射属性下的 PrincipledMaterial

U 比例 = 1 垂直比例 = 1

我都改成了0，但是什么都没变。我不得不再次在 3D 编辑器中重新加载场景。

色差不是问题。我必须适应一下光线等等

这里是更正 PrincipledMaterial 的摘录。

PrincipledMaterial {
                id: cUERO_NEGRO_material
                baseColor: "#ff534d30"

                roughness: 0.389465
                normalMap: Texture {
                    scaleV: 0
                    scaleU: 0
