I would like the opacity of the outer surface to be around .3 (i.e. opacity=.3) and the inner cylinder to be totally opaque (opacity=1). Given my method in the code opacity only seems to have an effect if it is included in a \psset{} macro in which case both surfaces are transparent. Including opacity=k in the directives for an individual solid has no effect on the individual surfaces.  Does deactivatecolor take opacity into account? Or is something else going on? Thanks, Jon

something like the attached?
