So at what point did you store the _activeContextID member attribute?
as it is only valid during a current Draw phase.

Hi Anders,
I remenber having such a problem with CEGUI and multitexturing, here is my
drawImplementation which works fine now :
void CEGUIDrawable::drawImplementation(osg::RenderInfo&
renderInfo) const
{
osg::State *state = renderInfo.getState();
if (state->getContextID() != _activeContextID)
{
return;
}
state->setActiveTextureUnit(0);
state->setClientActiveTextureUnit(0);
CEGUI::System::getSingleton().renderGUI();
state->checkGLErrors("CEGUIDrawable::drawImplementation");
}
But my problem was just CEGUI textures going all white when looking to a
multitextured object, so maybe you have a new one. :)
Good luck !
