Re: pickdata and select again....
As Mark suggested, maybe you can provide some more details?
I played around with this a little bit with texture mapped polygons. I even
threw in a semi-transparent polygon to trick it but to no avail. As far as I
can tell pickdata is returning sane results. How far off are your values
and what are your view settings? How are you using the pickdata method?
