HI Vincent, Perhaps everybody else like me is a bit confused by what you are actually after. The OSG supports multi-texturing, and shaders, the plugins are all orthogonal to final readering - all in all is most likely what you are trying to do is very straightforward. I can't really glean exactly what the problem might be, perhaps you are just tackling it in an awkward way that is confusing things.
