If you are doing these slightly non-standard things, you can gain a lot more
control by creating your own viewports and using the TileCameraDecorator to
control things.
The main concept of the ClusterWindow is to have a large Window that is
internally split between the cluster nodes. By default it just does an x/y
split
for simple tiled walls, bgut there is not reason to keep it at that. If you
make
the ClusterWindow configuration to be all horizontal and add as many Viewports
as you have servers with left/right to put them besides each other you can then
add TileCameraDecorators linked to the same Camera to control exactly which
part
of the screen is shown on which server.
Hope it helps
Dirk
