I am getting the following message when I unload a scene. I am simply deleting the entities I don't have to display anymore. QMetaProperty::read: Unable to handle unregistered datatype 'Qt3DRender::QBuffer*' for property 'Qt3DRender::QAttribute::buffer' What is the proper way to unload meshes in

I don't think that it exist a 3D format that is made to have a fast loading, obj, collada are text based format and even FBX that is a binary format seems to give fat and complexe hierarchy files. If you really need performances the best is to do a custom file format that feet your needs. For exem

[Interest] [Qt3D] OpenCL support

Hi, I found a really interesting SSAO post process (Line-Sweep Ambient Obscurance ), but the reference implementation is written in cuda and it exist a OpenCL port. So I would know if it can be integrated with Qt3D using OpenCL. If it's already possible to do it, do

[Interest] [Qt3D] Crash when using an empty vertex buffer

I am creating dynamic geometries and at some moment a geometry can be empty, that cause a crash. I think that it would be nice if the renderer was safer and avoid the draw call of empty geometries. It's like new and delete that manage correctly the allocation of 0 bytes. Else I'll have to manage t

Re: [Interest] Is there any plan to make property binding working in C++?

Exactly property binding is interesting when we are doing more complex operations, with your examples I don't really see where the connect solve a dependency graph. An example from our code : bool WallEntity::dimentionsVisibleBinding() { if (mWall.get(); == nullptr) // dimenti

[Interest] Is there any plan to make property binding working in C++?

Hi, Firstly I have to thank every contributors of Qt particularly mens from KDAB for such great things as QML and Qt3D. With QML I learn the property binding paradigm, which is a really big thing that can help to solve a lot of complex problems, but I think that it is not enough known. I really

Re: [Interest] Preferred way to create custom look-and-feel GUI

If you want something modern you should use QML. Maybe with QtQuickControls 2.0 to get controls, because QtQuick itself provides only primitives, Rectangle, Image, MouseArea,... but no buttons,... QML is made to be easy to customize instead of Widgets, you will also capable to do nice animations.

I think that is better to used a ShaderEffect instead of QtGraphicalEffects that comes with an FBO. An FBO can take a lot a GPU resources and doesn't works well with some Android phone due to bad drivers. I personally use this : ShaderEffect { visible: Qt.colorEqual(parent.color, "whi
