I have some operations that I need to do before the scene-graph start the rendering or a least be able to do an operation before a specific node is rendered.
I want to start by building the source code of the uber-shader used by my custom material. So I tried to use a QFrameAction on my root scene node, but the slot isn't called. I have attached the QFrameAction as component of root node and then connect my slot to it, but the slot is never called. My I missed something, or it is simply not the good way to do? -- Xavier
