Using QML Items as texture for custom QSGGeometry QML QQuickItem

Hi belab, Thanks for the suggestion however I really need to do is to get the image of a rendered QML Item (and its subtree) e.g. using a ShaderEffectSource and then using that image as a texture to use on another QQuickItem derived class which has custom geometry. As I said, I can grab the texture and I have the custom item. I just can’t create the texture in that custom item yet because I don’t know how to assign it from the ShaderEffectSource from QML. Any suggestions appreciated.
