hm, looking through the code of FBOViewport, it looks like something
broke it, sorry about that.
Please switch to using a SimpleStage, see my previous mail for pointers
to examples that use it and do pretty much the same as you want.

the scene as far as the application is concerned would not really have
to change, but you'd put a small tree on top of it:
root
|
+- SimpleStage
| |
| +- VisitSubTree -> ApplicationScene
|
+- VisitSubTree -> ApplicationScene
See Gerrit's mail for more info why you need VisitSubTree here.
If you don't want to update the FBO texture every frame, you can use a
traversal mask on the Node with the SimpleStage core and the RenderAction:
A node and its subtree are only visited if the bitwise-AND of the node's
trav mask with the action's trav mask is non-zero.

SimpleStage has a camera, a background and the left,right,top,bottom
fields let you restrict rendering to a sub-rectangle of your FBO, i.e.
they give you a viewport.
