Hi Neil,
The OSG places the plugins in an osgPlugins-version directory, while
the libraries will be placed in the lib (for .lib) and bin(for dll's)
directories respectively. This should be the same for your build from

Depending on what you need to do, additive blend (as it has already been
suggested) may work fine. Using ping-pong is not an option if you need
to accmulate the output in a triangle basis because it requires a buffer
swap per triangle to guarantee correct results.

For ECEF the vector length should be close to the earth radius. For flat

No you can't use the glare and dof effects without using a shader, you will
have to write your own shader to account for your material properties. You
can use the default shader as the base and then include your own shading
into that.
