You were asking about node masks and picking a few days ago, right? You
can use node masks for that too. Set the node mask of your HUD's root
Group/Transform to 0. This will cause it not to be rendered (and not be
pickable as well).
In OSG, the rendering is a traversal as well, so it has a traversal mask
(default 0xFFFFFFFF). It logical-ANDs that to the current node's mask
(also 0xFFFFFFFF by default) and if the result is nonzero, it goes into
the subgraph (until it gets to the leaves, which are drawn if the result
is nonzero). So by setting the mask of a node (or subclass of Node, like
Group) to 0, you are forcing a result of 0, since (anything) & 0 = 0.
You can get into clever uses of node masks to make something pickable
but not renderable, or renderable but not pickable, etc. Just remember
that it isn't an equality test, it's a logical AND, so you have to put
your binary hat on (assuming you're one of the 0001 out of 0010 who
understand binary). :-)
Hope this helps,
