[Radiance-general] RE : Light Shelf Reflections

[Andrew McNeil]

It looks like the changes you make to -dr and -lr are not being passed to
Radiance.
I recommend running radiance yourself from the dos prompt.  You many need
to install Radiance first (I'm not sure if ecotect's version of Radiance is
set up to be used from the command line).  Best bet is to use the NREL
installer (
https://openstudio.nrel.gov/getting-started-developer/getting-started-radiance
)

After you install Radiance, start the dos shell and change directory to the
location of the model files.  Then enter the following commands:

oconv mirror_scorrected_sky.rad mirror_scorrected.rad >
mirror_socorrected.oct
rpict -t 120 -vth -vp 9.628 4.564 6.510 -vd -1.701 0.360 -0.007 -vu 0 0 1
-vh 180 -vv 180  -lr 15 -dr 15  -i -ps 1 mirror_socorrected.oct >
mirror_socorrected.hdr
ra_tiff -z mirror_socorrected.hdr mirror_socorrected.tif
