My falsecolor keeps running wrong, I can't find the reason, I put the falsecolor code below, I hope to get everyone's assistance, thank you

Hi @Silash,

Try to install Radiance in the C drive. You can find the Windows installer (exe) at the bottom of this page.

Or preferably, in my opinion, install Ladybug Tools through the Pollination Grasshopper installer. You can read more about this in this announcement.
