[Radiance-general] Radiance-general Digest, Vol 159, Issue 12

Tue May 16 11:44:44 PDT 2017

Hi Everyone:
Thanks for the tips; much appreciated.

When I type in echo $RAYPATH, it returns  ".:/usr/local/radiance/lib"
When I type in echo $PATH, it returns "
/usr/local/radiance/bin:/usr/local/radiance/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin"

picture.cal is entered properly in the .rad file (no directory paths in
front of the command)
