Hi, I have to change to parent to nullptr to make some entities invisible, but when I put them visible back I get a crash.
The crash is a segfault in the method void Entity::setNodeManagers(NodeManagers *manager) because the this pointer is null. Here is the callstack : Qt53DRenderd.dll!Qt3DRender::Render::Entity::setNodeManagers(Qt3DRender::Render::NodeManagers * manager) Line 140 C++ Qt53DRenderd.dll!Qt3DRender::Render::RenderEntityFunctor::create(const QSharedPointer<Qt3DCore::QNodeCreatedChangeBase> & change) Line 562 C++ Qt53DCored.dll!Qt3DCore::QAbstractAspectPrivate::createBackendNode(const QSharedPointer<Qt3DCore::QNodeCreatedChangeBase> & change) Line 198 C++ Qt53DCored.dll!Qt3DCore::QAbstractAspectPrivate::sceneNodeAdded(QSharedPointer<Qt3DCore::QSceneChange> & change) Line 163 C++ Qt53DCored.dll!Qt3DCore::QChangeArbiter::distributeQueueChanges(std::vector<QSharedPointer<Qt3DCore::QSceneChange>,std::allocator<QSharedPointer<Qt3DCore::QSceneChange> > > * changeQueue) Line 120 C++ Qt53DCored.dll!Qt3DCore::QChangeArbiter::syncChanges() Line 180 C++ Qt53DCored.dll!Qt3DCore::QAspectManager::exec() Line 282 C++ Qt53DCored.dll!Qt3DCore::QAspectThread::run() Line 88 C++ Qt5Cored.dll!QThreadPrivate::start(void * arg) Line 380 C++ [External Code] [Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll] I am also curious to know what does the enable flag on QEntity, it seems easier to use it to control the visibility of object and maybe faster. PS: I am using the git branch 5.8 -- Xavier
