Hi Kyle,
Patch 0 is indeed the ground plane. If you didn't specify a ground in your scene description (i.e., no source with negative-Z) then this will be black. Photosphere doesn't know what to do when you give it a black HDR image.

Date: June 30, 2012 4:37:07 PM PDTI have added the -bn option and now have a good batch of sky subdivisions.
vwrays -ff vw | rtcontrib \-bn 146 @rtc\.opt \-ffc \\ (vwrays -d $vw) -V+ -f tregenza.cal -b tbin \
-o images/patches/p%03d.hdr \
-m sky_glow testroom_whitesky.octand a nice visualization with Andy's previous response to Ji:

I am still a bit confused regarding patch p000.hdr
When i attempt to open in Photosphere, i get : "Cannot map HDR pixels
in MapSubimage"Since the sky only needs 145 patches, the purpose of this p000.hdr is
a mystery. (Although i recall reading something about is purpose late
last night . . . a placeholder for the ground reflection if it is
added . . . ?)-Kyle
