Well, keep in mind that the graphics system used by
XObjView is *completely and utterly* different from
the graphics system used by XInteranimate (object
graphics verses direct graphics). And you can't mix
and match.

To get different colors in XObjView, you are going
to have to investigate the RBG_TABLE* keywords for
the IDLgrVolume object you are passing to XObjView.

Cheers,

David
