I'm trying to render some scenes above my native resolution that use
ambient occlusion, so I am using the external Tachyon renderer. However,
when I try to run the file render, the tachyon dat file is generated OK,
but the post-render fails because "tachyon_WIN32.exe is not compatible with
the version of Windows you are running" (Windows 7 x64, which is strange
because I've never had problems running a 32-bit program on here before).
Very well, I downloaded the x64 binary and tried to rerun it but the
post-processing doesn't generate anything.

My render command generated by the file render script is as follows:
render Tachyon image.dat "C:\Program Files (x86)\University of
Illinois\VMD\tachyon_WIN32.exe" -aasamples 12 %s -format BMP -res 1826 2084
-o %s.bmp

Another strange thing is that if I enter the above manually, the whitespace
in the path gives me fits. I tried escaping the backslashes and the
whitespace and it still did not cooperate. I also used curly braces in lieu
of the quotes and still, no go. Why are the post-render commands nearly
impossible to pass manually in Windows? I don't even know how it's possible
at this point and why the file render plugin can manage to do it correctly,
but I can't.

I've been playing around with this all day but can't get it to work. Been
using Windows shell as well as the Tcl interpreter in case it was a syntax
problem. Also reinstalled VMD. Help!
