[Radiance-general] genBSDF error

[Islam Mashaly]

Hello,
I'm new to the radiance thing so my question might seem an easy one.
I tried generating an .xml file for a window.rad file containing the following:****************************************************void glass windowglass003 .1 .1 .1
windowglass polygon window00120     .625      -1.3750     1.375     -1.3750     1.375     -.6250     .625      -.625****************************************************And in the genBSDF file I used the following command:
****************************************************genBSDF.exe srcwindow.rad > srcwindowbsdf.xml****************************************************
however I get the following error:
***************************************************Illegal division by zero at script/genBSDF.pl line 158.***************************************************
I tried looking any forums related to this error but I couldn't find any.
I would be grateful if anyone can guide me through the process of creating a genBSDF.xml file and adding it as a material.
Regards.
Islam Mashaly.
