> Not sure if this is a bug. A new program of mine creates a pvti file that
> reference two vti files in the same directory. No errors are produced when
> PV reads the pvti file but the 2nd vti file seems to be ignored.
>
> In the attached image the top object is what the pvti reader produces. A
> slice through just the right half has a min,max of 0,0.
>
> The middle object results when only the "left" vti file is read; and the
> bottom when only the "right" vti file is read. Obviously the "right" file
> contains valid numbers.
>
> The files without the binary parts are below. I hope someone can spot some
> simple mistake I've made.
