I can't load Texture with QVariant in QMetalRoughMaterial ? What happened With Qt3D 5.13.1 ?

[GeminiMan]

hello,
I tried to use QMetalRoughMaterial for my cube to see how it's work. i saw the example in QML and i tried to translate it in C++ code That's it :

Qt3DExtras::QMorphPhongMaterial *mat {new Qt3DExtras::QMorphPhongMaterial(this)};
mat->baseColor().setValue(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_col.jpg")));
mat->metalness().setValue(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_met.jpg")));
mat->roughness().setValue(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_rgh.jpg")));
mat->normal().setValue(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_nrm.jpg")));
mat->ambientOcclusion().setValue(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_disp.jpg")));

Not Working, so I say to go the documentation to see how the methods work, the properties are Qvariant type. I looked how to do, QVariant :: FromValue() it does not work either.

My question is how to get textures through qvariant or QAbsractTexture ?

Oh yes, the QTextureLoader does not work anymore? is it deleted in this version?

i tried this too nothing works

Qt3DExtras::QMetalRoughMaterial *mat {new Qt3DExtras::QMetalRoughMaterial(this)};
Qt3DRender::QTextureImage *baseColorTextureImage {new Qt3DRender::QTextureImage()};
Qt3DRender::QTextureImage *metalnessTextureImage {new Qt3DRender::QTextureImage()};
Qt3DRender::QTextureImage *roughnessTextureImage {new Qt3DRender::QTextureImage()};
Qt3DRender::QTextureImage *normalTextureImage {new Qt3DRender::QTextureImage()};
Qt3DRender::QTextureImage *ambientOcclusionTextureImage {new Qt3DRender::QTextureImage()};

MTexture *baseColorTexture = new MTexture(); //MTexture is inherit QAbstractTexture
MTexture *metalnessTexture = new MTexture();
MTexture *roughnessTexture = new MTexture();
MTexture *normalTexture = new MTexture();
MTexture *ambientOcclusionTexture = new MTexture();

baseColorTextureImage->setSource(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_col.jpg")));
metalnessTextureImage->setSource(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_met.jpg")));
roughnessTextureImage->setSource(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_rgh.jpg")));
normalTextureImage->setSource(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_nrm.jpg")));
ambientOcclusionTextureImage->setSource(QUrl(QStringLiteral("qrc:/texture/metal/Metal03_disp.jpg")));

baseColorTexture->addTextureImage(baseColorTextureImage);
metalnessTexture->addTextureImage(metalnessTextureImage);
roughnessTexture->addTextureImage(roughnessTextureImage);
normalTexture->addTextureImage(normalTextureImage);
ambientOcclusionTexture->addTextureImage(ambientOcclusionTextureImage);

mat->baseColor().setValue(QVariant::fromValue(baseColorTexture));
mat->metalness().setValue(QVariant::fromValue(metalnessTexture));
mat->roughness().setValue(QVariant::fromValue(roughnessTexture));
mat->normal().setValue(QVariant::fromValue(normalTexture));
mat->ambientOcclusion().setValue(QVariant::fromValue(ambientOcclusionTexture));
