sorry, I was just guessing at possible problems. We have had problems
with overlays and terrain texture units clashing, but I'm not sure it is

Terrain texture units can in newer osgdem be set with layer option.
I think the time laps when CMake was generating erroneous Config file under
Windows was very short, and I had no luck by building at this moment.
But having the ability to force CMake to regenerate this kind of file should
be useful in the future if others modifications come.

We'd run out of bits pretty quickly.

When do you change the node masks? Also, node masks are limited by the

Well you could do it many ways, it seems like you have 2 main states
pickable/not pickable then you have your views, you would not have a
seperate mask for every objects(If you want unique for every then you could

and with osg. It seems like whatever is drawn later occludes what is
already there. When viewer-frame() is called, even what should be clear
Hello Mark,
I've tried messing around with camera settings (and broken my
application in many interesting ways), but I can't figure out how to
avoid losing all of my already rendered stuff when I call
viewer-frame. I would prefer to have the osg objects interact enough

Hi,
I am working on quicktime real time streaming and hope can make it work as the

Thanks in
