Scratch that, forgot to set the item size to fill the window. Changing that
fixes it in the standalone example.

Hi guys, I
QRenderTarget nodes in the frame
graph. It is “illegal” to have this kind of graph with Scene3D?
Thanks!

3 different sub-trees in your framegraph. Each one will set the camera to use,
the filters to select the subset of the scene graph to draw and the FBO with
the target texture to render into.

If all you need is to have Scene3D as part of your QML but the entire entity
hierarchy come from C++, then you should be able to do that just by creating
the C++ entities and passing the root to the entity property of the Scene3D
item. You can set properties on QML items from C++ and you can re
some basic OpenGL.
If the frame is totally black, it’s a different problem you’ll need to debug,
but just a heads up that once you do get frames back, they won’t be what you
expect…

Hi Jason, you need to check the handle type on the QVideoFrame. If
input->handleType() == QAbstractVideoBuffer::NoHandle then you can map the
memory directly, as you've tried. But on Mac, the handle type is
GLTextureHandle and you need to write some OpenGL code to get the texture
handle, re
Hi Nikita, if you can visualize the different viewpoints inside a single
Scene3D object with a custom frame graph and viewports, that would be easy.
See the Qt3D viewports example for that approach. But I can imagine some
scenarios that require a more flexible layout.
If you need multiple

Hi everyone, between StencilMask, StencilTest, and StencilOperation QML items

straightforward with a custom framegraph. Specifically, I am trying to render
