Qt3D and post-processing

[kmedghaith]

Hi all,

I have some questions about post-processing in Qt3D. I have a scene built with tools provided by qt3d package (QGLSceneNode, QGLMaterial, ..) and drawn with a QGLpainter. My problem is that I do not see where and how can I do some processing on some objects. I would like to apply some filters, a glow for example on some objects in the scene using shaders. I've take a look on QGLShaderProgramEffect by doing a
@myNode-setUserEffect(...)@

but it seems that it is not possible to use it with the default effect for the same node.
Does anybody faced this issue ?

Thanks in advance.
G.
