[Radiance-general] Rtcontrib question

[Guglielmetti, Robert]

Hmmm, grabbed the HEAD release, compiled, and tried:

gensky 03 21 12 +s -a 40 -o 115 -m 115 | genskyvec -m 1 | dctimestep
./filename%03d.hdr > combined.hdr

But it just prints the usage/help line and produces a zero byte image. The
files exist, and there are noe 146 of them (-bn 146). Not sure what's wrong.
?
