Added SceneView::Options enum enetries APPLY_GLOBAL_DEFAULTS and CLEAR_GLOBAL_STATESET to control whether a _globalStateSet->clear() and _globalStateSet->setGlobalDefaults() should be called.
The problem seems to be that in osgViewer/Renderer.cpp those new enum values are not respected when sceneViewOptions for the scenes is calculated:
Renderer.cpp:399
unsigned int sceneViewOptions = osgUtil::SceneView::HEADLIGHT;
if (view)
{
switch(view->getLightingMode())
{
case(osg::View::NO_LIGHT): sceneViewOptions = 0; break;
case(osg::View::SKY_LIGHT): sceneViewOptions = osgUtil::SceneView::SKY_LIGHT; break;
case(osg::View::HEADLIGHT): sceneViewOptions = osgUtil::SceneView::HEADLIGHT; break;
}
}
...
_sceneView[0]->setDefaults(sceneViewOptions);
_sceneView[1]->setDefaults(sceneViewOptions);
This leads to a broken Scene in our application. As I've no idea about the internals of osg (I just searched this bug) I hope this is enough to fix the problem.
Thx,
