I've got the same issue with Qt3DExtras::QText2DEntity. But I found the workaround. Look like there is a bug? in implementation of Qt3DExtras::QText2DEntity that prevents internal initialization (QText2DEntityPrivate::setScene is never called). This happens when scene is already visible and Qt3DExtras::QText2DEntity is created with parent entity passed to constructor. The workaround I used to make it work is to pass nullptr (which is default) as parent in constructor and call ->setParent(parentEntity) in separate call. m_text2dLabel = new Qt3DExtras::QText2DEntity(); m_text2dLabel->setParent(parentNode);

I'm not familiar with Scene3D, but I once tried a stress test without QML. I think I think I deleted the entities and their added components with entity->deleteLater(); In the Basic shaped c++ example, the parent of an entity just gets set to nullptr to disable it.

@m.sue That's good to know, thanks for the link!

Hi, You can write to the Qt Interest mailing list, see http://lists.qt-project.org/mailman/listinfo. There Sean Harmer himself may answer the one or other question about Qt3D if you don't talk badly about his baby right in your first mail. -Michael.

Hi THE_MASTER Did you realize your CAD-Project with QT3D? Looking for information about QT3D I found your posting. I have to realize a small 3D-CAD as part of a project. First I wanted to do it with OpenCascade, but the support....

Hi, You can add a light with the following code (for example): Entity { id: root ... Entity { id: lightEntity components: [ DirectionalLight{ color: Qt.rgba(1, 1, 1, 1.0) intensity: 0,5 enabled: true }, Transform{ position: Qt.vector3d(5,5,5) } ] } }

@Aras Hi, any update on the above query? Thank you.

@Dabulla Hi! Would be great if you'd file a bug report for this PointSize RenderState issue. Thank you :)

Hi, Qt3D being still a tech preview and it's API evolving, I'd recommend posting this question on the interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.

Hi, The module being pretty new, I'd recommend posting that question on the interest mailing list. You'll find there Qt3D maintainers/developers. (This forum is more user oriented)

Thanks, I'll do that!
