Hi Yura,

The scene graph state works top down, so parent state affects the
children.  If you set parents NodeMask to 0 then it's children will
not be traversed.  This is fundamental to the design of the OSG and
one of it's great strengths.

The real question I'd have is what you mean by hiding the parent as
it's only leaf nodes that contain osg::Geometry/Drawble that can be
rendered, internal nodes of the scene graph can't ever be seen
themselves graphically.  Given this is really hard to know what you
mean, as it doesn't make any sense in the context of how the OSG

Could you take a step back and describe what you are trying to achieve
rather than how you are trying to achieve it, a higher level
explanation will enable us how you should try and achieve it.
