I assume you set up your CameraNode with the same width and height as
your _capImage? Sorry, I have to ask ;)
Other than that I can't think of much that could be the problem.
Could it be some weird byte alignment problem? I think I'd first try
GL_UNSIGNED_BYTE instead of GL_FLOAT and something less ARBy for the
internal texture format.

Terry,
Sorry, I covered way too many topics. Let's step back a second.
The 1/4 issue:
It appears that when I set up a CameraNode with:
setRenderTargetImplementation(osg::CameraNode::FRAME_BUFFER_OBJECT);
and
attach(osg::CameraNode::COLOR_BUFFER, _capImage.get());
I get only 1/4 of the rendered area. I'm not sure why. The image is
set up thusly:
_capImage = new osg::Image;
if (!_capImage.get())
return false;
_capImage->allocateImage(width, height, 1, GL_RGB, GL_FLOAT);
_capImage->setInternalTextureFormat(GL_RGB16F_ARB);
I had this same problem with OSG 1.0 (but didn't realize it until
later).
Any ideas on were to look? Could it be that glReadPixels isn't reading
enough?

Let's talk about the viewport issue in another thread.
