I think I have something close to that there:https://github.com/ossia/score/blob/master/src/plugins/score-plugin-js/JS/Executor/GPUNode.cpp#L284 Line 289 the rendertarget on which QtQuick is going to be rendered. Then the actual rendering is there: https://github.com/ossia/score/blob/master/src/plugins/score-plugin-js/JS/Executor/GPUNode.cpp#L370-L426 Afterwards what's in the render target can be used in further render passes like any other texture to have your overlaid content. It's not perfect as I haven't been able to make Animators work though, but what I'm missing with this is likely not related to QRhi ! Also I haven't been able to do it without private API (https://github.com/ossia/score/blob/master/src/plugins/score-plugin-js/JS/Executor/GPUNode.cpp#L392) - if there's any way to do it I'd love to know. Cheers, hopefully this helps!
Thanks for the reply. There's unfortunately one further twist I forgot to mention: this is for GammaRay, so while that means I'm not afraid of using private APIs, I can't really modify the rendering code itself (e.g. to reroute it through QQuickRenderControl and "manually advance it", like you're doing); I can pretty much only listen to QQuickWindow's signals :)
