Ok, thanks. That means it doesn't work out of the box and the OpenSG
classes have to be extended to support it? It would be nice if the
scenegraph could be synced on both sides.
Is there a working C++ sample with SortFirst which I can examine? Cannot
find one in the Examples directory.
Thanks in advance!

the SortFirst/SortLast cluster windows do something along those lines,
each render node produces part of a final image that is composited on
the client for display. While those work with only transmitting colour
(and depth) data, I don't see anything that would prevent transmitting
additional buffer contents as well - you are going to consume a lot of
network bandwidth though.
Cheers,
Carsten
