I'm trying to model fixed slats at arbitrary angles that have been covered up by diffusing roller shades. Is there a workflow of radiance routines (e.g. genblinds, xform, etc.) that can make this a simple procedure?

I was working on this question here, but that thread is now focussed on work-arounds in WINDOW.
