You probably have to adjust option -ab when you call rillum (by default -ab 0 is assumed I think)
For instance rillum -ab 1 should be OK

Objet : [Radiance-general] Direct horizontal illuminance
Dear all,
I have a problem on finding the direct horizontal illuminance (DHI) following the steps provided by Dr. Phillip Greenup (Page 253 @ goo.gl/Bw68WQ)
I am able to find the horizontal global illuminance using "rillum.exe". However, I am not able to find out the direct horizontal illuminance. It said:
warning - no light sources found
0
It should not be zero. How can I solve this problem? Hope you guys can help.
FYI, this is my sky.rad.
