Incident Radiation: null results

Hi, I have previously used this radiation script successfully for another project, but for this particular file, the results come out as ‘null’ and therefore does not show up in Rhino. Any guidance or support would be much appreciated, thank you!

Screenshot below for reference.

Kind regards,

Hi @Cheunglc98, welcome to the forum!

Looking at the screenshot you need to turn the run boolean input to True

Cheers, Charlie
