Dear Colleagues,
My sincere thanks to Andy and everyone else who have tried to help me in
the last few days with my light shelf reflection problem. Finally I have
some results which are more convincing:
The directionality (surface normal) of the the ceiling mirror surface seem
to be one of the major things that was throwing me off. My next step is to
import the values of these multiple reflections on to a simulation grid so
that I can plot them as a graph.
Your support meant much to me.
Shamim.

Shaim,
Can you try typing the commands I sent directly at the dos prompt?
That would tell us if it is a problem with the outdated version of
Radiance you are using or if it is a problem with the Ecotect Radiance
Control Panel. I still think it is a problem with the latter as the
commands settings didn't get into the header created by Radiance.I'd rather determine if Ecotect related software is the cause now, rather
than going further assuming that it is Radiance (which I doubt, but I am
biased).Andy

1998 is pretty old--it's possible we're giving you advice for newer
versions.NREL has a newer release of Radiance for Windows. I'm pretty sure you
can hook it up with Ecotect, but I'm not sure exactly how. Anyone done
this?Randolph

I looked at the files generated by Radiance via Ecotect and it looks
like the version of Radiance it is using is 3.1.8. Here is a copy of one

If not, "getinfo foo.hdr" will identify the version of Radiance that
generated foo.hdr.Randolph
