Hi Rômulo,

You don't say what problem you are having or what specific doubts you
have, so we don't have any clues to if there is problem we are looking
for or whether you just want a 3rd party view of whether the code is

Once you provide so guidance on the problem you are having I'l have a
look at the code.

As general comment, the OSG can nest Render to Texture techniques (so
RTT passes can have other RTT passes that are enclosed in their
subgraphs and these will be rendered first) as well as allow you to
control rendering order explicitly using Camera::setRenderOrder(..).
This means you can chain any number of RTT passes together, it could
handle hundreds if you really wanted it to.
