Hello Mr. Carsten,
Thanks for the program it worked like that.
manager()->getWindow()->activate();
manager()->getWindow()->frameInit();
RenderAction *rAct = RenderAction::create();
m_fbovp->setParent(manager()->getWindow());
rAct->setWindow(manager()->getWindow().getCPtr());
m_fbovp->render(rAct);
m_fbovp->setParent(NullFC);
Thanks again.

From the filename used in the code you posted, I guess you are on
windows? In that case the dailybuilds come with release and debug
(appended D, e.g. OSGBaseD.dll) libraries. Or are you not using one of
the dailybuilds, but a prebuilt version from a different source ?
Unfortunately I can not help with setting up VS to use the debug libs,
but if you try that, please be very careful not to mix any debug and
release libs, it causes very interesting errors at runtime.

hm, could you compare the way you set up the FBO and the textures with
how it is done in testFboVP.cpp (attached), please ?
Comparing the code there with what you sent, there seemed to be some
minor differences, like a missing m_fbovp->setFboOn(true) and
fbotexi->setWidth, fbotexi->setHeight instead of fbotexi->set (the
latter actually allocates memory for the image, so this might be
significant, although in theory the FBO should reallocate the image).
Maybe there is something else I've overlooked.
Thanks,
Carsten
