Hi all,
I've just managed to solve the second main problem I had been
encountering, and I wanted to share the solution in case it helps
someone else out of the same fix.
A bit of experimentation showed that with the updated camera code, the
only overlay that was still vanishing when shadows were used was my
CEGUI Drawable (CEGUI 0.7.5). The other overlays were actually fine.
In the Drawable that I am using, during drawImplementation, the state is
set up to lead into CEGUI's renderGUI call roughly as follows (please
excuse transcription errors):
osg::State *state = renderInfo.getState();
state->disableAllVertexArrays();
state->disableTexCoordPointer(0);
glPushMatrix();
glPushAttrib();
...
CEGUI::System::getSingleton().renderGUI();
If I was using a ShadowedScene with any ShadowTechnique at all, the GUI
would vanish. Up until that point it would render fine.
The fix ended up being to reset a bit more state (after the
"disableTexCoordPointer" call:
state->setActiveTextureUnit(0);
state->setClientActiveTextureUnit(0);
I'm actually quite surprised that this worked, but it did. I wonder if
there is a better way to do this, but it seems sufficient in my case.
Cheers,
Garth
