Hi Joe,
OK, now understood. The inheritance of the osg::CullSettings from the
master Camera is controlled by the inheritance mask, you can switch
off bits you don't want to inherit. Note osg::Camera inherits from
CullSettings.
If you want the slave to be totally independent w.r.t the various cull
settings then do:
slavecamera->setInheritanceMask(osg::CullSettings::NO_VARIABLES);
Before you add it to the View.

Sorry for the confusion - it all made sense in my head!
Here's another stab at it:
In View.cpp line 135 the View::addSlave(cameraX,..) method calls updateSlave().
In View::updateSlave(...) at line 121 cameraX's mask is reset:
slave._camera->inheritCullSettings(*_camera);
so if I do this:
cameraX.setMask(bla);
view1.addSlave(cameraX,...);
The mask for cameraX will be reset to match the mask of view1's camera.
But if I change the order of these calls:
view1.addSlave(cameraX,...);
cameraX.setMask(bla);
The camera's masks will be independent.
thanks!
-Joe

Hi Joseph,
There isn't any code that sets the NodeMask on a slave in core osg or
osgViewer, so I'm a bit confused by your assertion.
Could you explain specifically what lines of code you are talking about.
Robert.
