Hi Michael,

I have just reviewed the code and guess that the problem is that
camera is never set up for the subgraph.  The update code obviously
should be a bit more savy about the test as whether to set up the
camera or not - perhaps some kind of dirty mechansim is required.

Hi everyone,

Since upgrading to OpenSceneGraph 1.2 I've noticed a problem with the
OverlayNodes that I was using.  I was previously using version 1.0.

I'm using an OverlayNode with continuous updating set to false and the
overlay no longer displays.  I am calling dirtyOverlayTexture() when the
subgraph is set or changes so that's not the cause.  Everything works
fine if I set continuous updating to true.

I think the problem is related to the local camera update code in
OverlayNode.cpp being moved into the update traversal.  It appears that
this code will now never be called if continuous updating is set to
false.  Could this be the reason I'm not seeing my overlays?  Or am I
likely doing something wrong in my code that has been exposed by a fix
in 1.2?

Thanks,
Michael
