Qt3DExtras Weird behaviour with materials

BuzzBen

Hi! This is my first entry I hope I can get some knowlegable fellow to help

Release: Qt 6.4.3
Language : C++
Compiler: 6.4.3_msvc2019_64
IDE: Visual Studio Community 2022 (17.4.3)

Required modules:

#include <QApplication>
#include <Qt3DCore/QEntity>
#include <Qt3DCore/QTransform>
#include <Qt3DRender/QCamera>
#include <Qt3DExtras/Qt3DWindow>
#include <Qt3DExtras/QOrbitCameraController>
#include <Qt3DExtras/QSphereMesh>
#include <Qt3DExtras/QTorusMesh>

Problematic Modules :

#include <Qt3DExtras/QGoochMaterial>
#include <Qt3DExtras/QMetalRoughMaterial>
#include <Qt3DExtras/QDiffuseSpecularMaterial>
#include <Qt3DExtras/QTextureMaterial>
#include <Qt3DExtras/QPhongMaterial> // deprecated class
#include <Qt3DExtras/QPerVertexColorMaterial>

Scene creation Code: (example using class QPerVertexColorMaterial)

Qt3DCore::QEntity* createScene()
{
	Qt3DCore::QEntity* rootEntity = new Qt3DCore::QEntity;

	Qt3DRender::QMaterial* material = new Qt3DExtras::QPerVertexColorMaterial(rootEntity);

	Qt3DCore::QEntity* torusEntity = new Qt3DCore::QEntity(rootEntity);
	Qt3DExtras::QTorusMesh* torusMesh = new Qt3DExtras::QTorusMesh;
	torusMesh->setRadius(5);
	torusMesh->setMinorRadius(1);
	torusMesh->setRings(100);
	torusMesh->setSlices(20);

	Qt3DCore::QTransform* torusTransform = new Qt3DCore::QTransform;
	torusTransform->setScale3D(QVector3D(1.5, 1, 0.5));
	torusTransform->setRotation(QQuaternion::fromAxisAndAngle(QVector3D(1, 0, 0), 45.0f));

	torusEntity->addComponent(torusMesh);
	torusEntity->addComponent(torusTransform);
	torusEntity->addComponent(material);

	Qt3DCore::QEntity* sphereEntity = new Qt3DCore::QEntity(rootEntity);
	Qt3DExtras::QSphereMesh* sphereMesh = new Qt3DExtras::QSphereMesh;
	sphereMesh->setRadius(3);
	sphereMesh->setGenerateTangents(true);

	return rootEntity;
}

With the main function:

int main(int argc, char* argv[])
{

	QGuiApplication a(argc, argv);

	Qt3DExtras::Qt3DWindow view;

	Qt3DCore::QEntity* scene = createScene();

	Qt3DRender::QCamera* camera = view.camera();
	camera->lens()->setPerspectiveProjection(40.0f, 16.0f / 9.0f, 0.1f, 1000.0f);
	camera->setPosition(QVector3D(0, 0, 40.0f));
	camera->setViewCenter(QVector3D(0, 0, 0));

	Qt3DExtras::QOrbitCameraController* camController = new Qt3DExtras::QOrbitCameraController(scene);
	camController->setLinearSpeed(50.0f);
	camController->setLookSpeed(180.0f);
	camController->setCamera(camera);

	view.setRootEntity(scene);
	view.show();

	return a.exec();
}

Expected behaviour : Run without issue.. (obviously)

Current Behaviour
With classes:

Qt3DExtras::QPerVertexColorMaterial
Qt3DExtras::QGoochMaterial

The geometry is not rendered at all.

Otherwise, with classes:

Qt3DExtras::QMetalRoughMaterial
Qt3DExtras::QDiffuseSpecularMaterial
Qt3DExtras::QTextureMaterial
Qt3DExtras::QPhongMaterial

The geometry renders correctly but a "memory access violation" exception is raised whenever the app is closed.
(Raised in QATOMIC_CXX11_H in a pile of 37)

N.B. This code is partially inspired from Qt 6.4.3 documentation: Qt3D simple example. Some parts from the original example were not compiling so they have been removed.

Any idea?
