Sean Harmer helped me with my little problem, thank you very much. There were two problems:

I have to used either diffuseImage->setSource((QStringLiteral("qrc:/diffuse.webp")); or diffuseImage->setSource((QUrl::fromLocalFile(QStringLiteral(":/diffuse.webp" ))); > material->diffuse()->addTextureImage(diffuseImage); > entity->addComponent(mesh); > entity->addComponent(material); >And if I use this: > auto material = new Qt3DExtras::QNormalDiffuseMapMaterial(); > [...] > ... my mesh displays in simple dark blue and I get the same debug messages. For QNormalDiffuseMapMaterial the mesh has to have a tangentAttribute, which mine did not have.
