Geco to radiance

I have a problem about how to activate the radiance througn geco plug-in. 

Cause the daylight analysis of the Ecotect is not based on direct light on the exact time of a day,so i have to turn to Radiance to continue the analysis.

So here is the problem ,although i can activate the radiance through ecotect, i cannot activate it in the geco plug-in. The analysis of the radiance cannot feed back to the grasshopper.

Maybe there is a way by adding Lua script,but the source code is too difficult for me to edit.

Do anyone know how to solve this problem?Thanks
