So I finally found a workaround for that weird state bug. If I add an
empty shader Program to the top of my scene like so:
Program* rootprog = new Program;
mRoot->getOrCreateStateSet()->setAttributeAndModes(rootprog,
osg::StateAttribute::ON);
Then I don't see the wrong shader getting applied anymore. So it
seems that explicitly telling OSG to turn off shaders fixes the
problem. Hey Robert, is that a good clue to where the problem might
be? I still don't grok all the internals of the OSG state code well
enough to figure this out.
Its certainly another useful clue. In theory you shouldn't need to
set an default Program to switch off GLSL programs, as osg::State
should create one automatically for you when the first Program is
applied.
Robert.
