The rendered image is missing my wallpaper.<br>
If I add the camera as a slave camera to the main camera I just get
an empty black image.<br>
Actually I also don't understand the difference between slave and
child cameras here. I know you explained it recently :-)<br>
Why does the slave camera give an empty image but the child camera
doesn't?<br>
<br>
BTW. I wrote my code here with the background of giving an example
to others looking for functionality like that.<br>

<pre wrap="">Hi Werner,
In principle what you are doing should be possible. What is going
wrong in your instance is impossible to say without seeing how you are
setting up the viewer Camera's and the in scene graph Camera's.
Robert.

<pre wrap="">Hi all,
sorry for so many questions today.
My scene graph has additional cameras as children somewhere in the scene
graph.
For example a hud camera for a background image.
I do screenshots by adding a slave camera to the main camera which renders
the scene to the FB.
Unfortunately this rendering doesn't show the parts of the nested cameras,
i.e. no
background wallpaper.
What is the recommended way to solve this?
Thanks for any help.
