You can do that, or you can create a plug-in that intercepts matrix-shaper pipelines and apply the slope limiting. I would try the optimization or the interpolation plug-in types. If you use interpolation you can slope limit every single 1D table-based curve. Keeps in mind many people prefer to *not* slope limit, specially on low gamma spaces. Regards Marti.
