[osg-users] Using NodeMask...

[Vincent Bourdier]

Hi Art,

I've tried something like that :

   geodeEarth->setNodeMask(0x5);
   pViewer->getCamera()->setCullMask(0x2);

It gives me the result i was waiting for : all is visible, only the earth is
not.
It isn't possible for me to set all other nodes, because I load the
geometries form an IVE file.

If the default mask is 0xffffffff, I'm surprised that is works well...

Thanks,

Vincent.
