Hello David,
Thank you very much for your reply. Actually the sky radiation settings 
I need to edit are: Haziness factor (Linke factor), which has a range 
from 3 to 40, And Scatter factor (Reitz factor), which has a range from 
0 to 1. I found only Cloudiness in the documentation of components in 
Type69. Do you know which input in which Type is suitable for the 
mentioned factors ?
Best regards
Karim
