He's suggesting that rather than

    #declare Whatever = isosurface {...}
    ...
    object { Whatever }

you should use (at least temporarily)

    isosurface {...}

as this will allow POV-Ray to give you a warning if it thinks your
max_gradient is a poor choice (whether unnecessarily high or too low).


Alternatively, use the brand-new development release I posted about a
couple of minutes ago, which should be able to do the same stunt without
any changes to your scene file.
