Hi, can you file a JIRA with a small test case please?

Yes I had this issue too, but when trying to share my QShaderProgram not changing parents. I simply can't progress as fast as want because of a lot of small bugs like this one and sadly I don't know how the backend is supposed to work to be able to contribute. In our homebrew engine I had similar issue, and the simplest way to solve them was to check ptr in the 3D engine instead of using assert, because it can be much hard from the user view to ensure the validity of all nodes. 2016-10-26 16:56 GMT+02:00 Oleg Evseev <ev.m...@gmail.com <mailto:ev.m...@gmail.com>>: Hi, I had problems similar to what you describe https://bugreports.qt.io/browse/QTBUG-55093 <https://bugreports.qt.io/browse/QTBUG-55093> in qt 5.7. I haven't check it on 5.8. 2016-10-26 16:37 GMT+03:00 Xavier Bigand <flamaros.xav...@gmail.com <mailto:flamaros.xav...@gmail.com>>: 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 140C++ Qt53DRenderd.dll!Qt3DRender::Render::RenderEntityFunctor::create(const QSharedPointer<Qt3DCore::QNodeCreatedChangeBase> & change) Line 562C++ Qt53DCored.dll!Qt3DCore::QAbstractAspectPrivate::createBackendNode(const QSharedPointer<Qt3DCore::QNodeCreatedChangeBase> & change) Line 198C++ Qt53DCored.dll!Qt3DCore::QAbstractAspectPrivate::sceneNodeAdded(QSharedPointer<Qt3DCore::QSceneChange> & change) Line 163C++ Qt53DCored.dll!Qt3DCore::QChangeArbiter::distributeQueueChanges(std::vector<QSharedPointer<Qt3DCore::QSceneChange>,std::allocator<QSharedPointer<Qt3DCore::QSceneChange> > > * changeQueue) Line 120C++ Qt53DCored.dll!Qt3DCore::QChangeArbiter::syncChanges() Line 180C++ Qt53DCored.dll!Qt3DCore::QAspectManager::exec() Line 282C++ Qt53DCored.dll!Qt3DCore::QAspectThread::run() Line 88C++ Qt5Cored.dll!QThreadPrivate::start(void * arg) Line 380C++ [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.
