Render overlay on top of cegui window

[1337]

I'm running out of ideas... So I would like to actually show what I see. Because it's really strange.
At the moment, my code is using a RenderQueueListener and I'm hooked into the Overlay ID on renderQueueStarted().

This is what I expect (image taken with Ogre 1.6 and CEGUI 0.6.2):


This is what I get witout doing anything apart from showing the console:


And this is what it looks like after focusing the first button:


I also checked to see what happens if I hook into renderQueueEnded --> as expected, I cannot see anything at all.

Any ideas how this could happen?

Hi,

Reset the scissor test area?

CE.

That was exactly the kind of answer I was hoping for by posting these pictures! I have (or rather had) no idea what the scissor test was, but I managed to solve the problem.
Thank you very much, I would have never, ever figured it out on my own!

As for the solution, I made a little hack:

Code: Select all

        void renderQueueStarted(Ogre::uint8 id, const Ogre::String& invocation, bool& skipThisQueue)
        {
            if (id == Ogre::RENDER_QUEUE_OVERLAY && invocation.empty())
            {
                CEGUI::System::getSingleton().renderGUI();
                Ogre::Root::getSingleton().getRenderSystem()->setScissorTest(false);
            }
        }


I would suggest to add this to the OgreRenderer as I might not be the only one who still needs the RenderQueue listening.
