No bug, you are just trying to do something in a completely wrong way.... As I said NodeMask works just fine, if you want another alternative you can just put a Switch node above the RTT Camera. > More explanation about why I am doing it this way: > > I have a node that will modify any camera that actually targets the node for > rendering. > The node will put any current render camera into RTT mode, and have > post-render cameras as children that will post-process the result.

It really sounds like you are making a relatively straight forward problem really complicated. Have 100 RTT Camera's in the scene graph is not a big issue for the OSG. Trying to reuse Camera can be done but it's really awkward, and is more likely to cause you more grief than you solve anything. Also you having more grief pushes the mailing list to try and help you doing something which is in the end rather counter-productive, personally I have better things to do.
