Hi Jason,
In principle this should work, but looking at the relevant code in
src/osg/CullSettings.cpp and src/osgUtil/CullVisitor.cpp it looks like
the which the settings are inherited, the actual traversal mask of the
NodeVisitor isn't set up, which is what will be required. Adding this
will require a modification to the apply(osg::Camera&) method in
CullVisitor.cpp.
Something like:
bool hasSetCullMask =
(camera->getInheritanceMask() & osg::CullSettings::CULL_MASK)=0;
if (hasSetCullMask)
{
setTraversalMask(camera.getCullMask());
}
Please tweak the code and see how you get on,if it fixes the problem
then please send the working code to osg-submissions so I can
integrate it.
Robert.

I have a scene graph that contains a number of osg::Camera's that are
used to produce shadow maps. There are certain elements of the scene
that exist for illustrative purposes and should not be used to create
shadows. I have tried using the cullMask to disable the drawing of these
elements during shadow map creation with the following:
#define SHADOW_CULL_MASK 0x00010000
int im = camera->getInheritanceMask();
im &= ~(osg::CullSettings::CULL_MASK);
camera->setInheritanceMask( im );
camera->setCullMask(SHADOW_CULL_MASK);
And then for my scene element:
element->setNodeMask(1);
The osgUtil::SceneView is left with its default settings.
This setup does not work however. The element still produces a shadow.
Any ideas why this doesn't work?
Thanks,
Jason
