I ran into a problem. I used the HB Radius component to calculate the annual illuminance, but it was nega

tive. Why

Hi @tangtang,

Have you tried to increase the Radiance parameters with the HB Radiance Parameter component?

I tried to add the HB Radiance Parameter, but there are still negative illuminance values, which are a little less than the negative values without adding the HB Radiance Parameter. How can I set it so that there are no negative values,

Hi @tangtang,

The parameter settings you have on your image usually should do it. Are you able to share your Grasshopper file?
